Sadie Kane's History
Early Life
Sadie Kane was born in California on March 17th, 1997, to Julius and Ruby Kane two years after the birth of their first child, Carter. On her sixth birthday party, she and Carter had a fight about blowing the birthday candles, and when they triggered each other's powers, they accidentally made the birthday cake explode.
Life with Grandparents
Later that same year, Ruby Kane died while releasing Bast from her prison (Cleopatra's Needle) in the Duat while she was fighting a monster named Apophis. Although Julius wished to keep both his children, Sadie's grandparents, Mr. and Mrs. Faust, took him to court and won custody of their granddaughter, with Carter and Julius only able to visit her twice a year.
The House of Life may have manipulated this outcome to keep Sadie and Carter separate. Sadie then began to live in London as an English schoolgirl and eventually lost her American accent for an English one. She has two best mates at school, Liz and Emma. Her father gave her a cat, Muffin, who was, in reality, the host of the goddess Bast.
Sadie would sometimes go into the Egyptian section of bookstores and read books her father wrote so she could feel a connection to him.
The Red Pyramid
Six years after the death of her mother, Carter and her father visit Sadie on Christmas Eve and go to the British Museum. There, Julius attempts to summon Osiris but accidentally summons Set, Nephthys, Isis, and Horus as well. Isis takes Sadie as a host and Horus takes her brother. Set, meanwhile, kidnaps Julius, who is now possessed by Osiris. Soon, her uncle, Amos Kane, takes Sadie and Carter to Brooklyn and tells them of their ancestry and that they are magicians. Not long later they are attacked by longnecks and are forced to flee. She and Carter are able to escape to the First Nome with help from Bast and Zia Rashid. There, Sadie has a vision of Osiris being tricked by Set on his birthday thousands of years ago. In addition to that, she and Carter learn the basics of magic, but their training is cut short when the late Chief Lector Iskandar dies and is replaced by Michel Desjardins, who orders their execution for hosting gods.
Sadie and Carter run away to Paris, evading the House of Life and reuniting with Bast. While attempting to find a way to stop Set, she and Carter travel to the Land of the Dead, where she meets Anubis, who she realizes is the cute boy she had been seeing in her ba visions. After talking in a New Orleans graveyard, Anubis gives her the Feather of Truth after asking her three questions while she held it and made her promise never to tell a lie while holding it and to listen to his mother, Nephthys.
From there, Sadie and Carter reunite with Amos and Zia and set out to stop Set. During the final battle, Sadie is able to act as one with Isis, and forces Set to realize that he was being controlled by Apophis and, using his secret name, makes Set swear to fight Apophis. Sadie then asks Isis to leave her body and returns to Brooklyn with her brother and uncle.
The Throne of Fire
Following the rise of chaos, Carter and Sadie decide to stick to their plan of reviving Ra the sun god by finding and chanting the three sections of the Book of Ra. They choose to isolate themselves from their friends and trainees of Brooklyn House. They have already successfully stolen one of the scrolls by infiltrating the Brooklyn Museum. While in the said museum, Sadie catches two of her trainees, Walt and Jaz, holding hands and talking. Sadie feels a twinge of jealousy because she likes Walt. She had spent five months brooding over Anubis, and now Walt apparently likes someone else. The second scroll's whereabouts are unknown while the other is claimed to be with Russian assassin Vladimir Menshikov who is targeting Brooklyn House. Yet before setting off, Sadie enjoys her birthday in London.
It turns out Sadie had walked into a trap made by Nekhbet, the Vulture Goddess, and Babi the Baboon god, who turn out to be using Sadie's Gran and Pop as hosts. Sadie is chased over London and is given a knife by Anubis, which is to help awaken Ra. Anubis also kissed her while wishing her happy birthday. Sadie is saved by Bes, the dwarf god, and afterward is joined by Carter as the three plunge into St. Petersburg, Russia.
Once there, Carter and Sadie break into the 18th nome to collect the second scroll owned by Vlad himself. They overhear Vlad associating with Set who Sadie releases to assist the siblings. While trying to escape, Carter is bitten by a two-headed serpent. Set gives the destination of Zia Rashid and the last scroll to Sadie for his secret name. Sadie agrees but makes him agree not to hurt the Kane family, and afterward, heals Carter by learning his ren. After Sadie and Carter discuss plans, Carter vows to rescue Zia along with Bes, while Sadie searches along with their trainee Walt Stone for the final scroll.
Sadie finds out that Walt is dying from a family curse, the same that other pharaohs like King Tut were affected by. She is very shocked by this and when telling the story quotes "I think I may have kissed him, or possibly slapped him." They are attacked by golden Roman mummies and a ghost called "Mad Claude" but are saved by the crafts of the god Ptah. Along with the scroll, Sadie and Walt leave to Cairo along with Carter, Bes, and Zia. In a bad dream, Carter finds that Brooklyn House is under siege by the House of Life. Walt and Zia leave to Brooklyn to help while Carter, Sadie, and Bes descend into the Duat to find Ra.
They come across gods and lakes of fire but at a nursery home Bes comes across a woman or hippo from his past, Tawaret the hippo goddess. With her help, they track down Ra and awaken him. When they find Ra, he is senile and a gentle old man acting like a toddler. Yet they find they had already lost and Menshikov had closed the gates to the prison of Apophis and is now loosening the giant snake's bonds. The trio along with Ra come across Carter and Sadie's parents and gamble with the Moon god, Khonsu, for a few extra hours for them to catch up to Vlad. Bes gives up his ren for the two to succeed. Carter and Sadie come face to face with Vlad who is now hosting Aphopsis. Desjardins arrives and banishes Aphopsis for at least a few more months or even weeks to give the Kanes a little more time, yet dies doing so. Carter and Sadie arrive at Brooklyn house to end the battle. At the end of the battle, Sadie summons the wings of Isis to command the magician's attention, this works and she tells them the story of what happened while they were resurrecting Ra.
Bes ends up at the nursing home not remembering who he is. Amos becomes Chief Lector and tries leading the magicians into a new age. Sadie vows to cure Bes and Walt. Ra becomes the leader of the gods again. Zia and Walt are connected to the upcoming war in a big way. By the end of all this Sadie says "I am completely torn between two amazing guys---one who's dying and another who's the god of death. What sort of choice is that, I ask you?"
The Serpent's Shadow
Sadie is at the Nome in Texas. She, Carter, and the other initiates they brought with them are there to steal the book of overcoming Apophis. Apophis shows up at the museum and Sadie must use Ma'at to restore the order. Sadie then passes out and wakes up seeing Isis and her mother. She then sees Anubis who tells her that she has the right idea of looking at what's not there. Anubis comes to Sadie at her school dance to tell her about sheuts and how Apophis' may be the key to defeating him. This causes Sadie to come up with a plan to restore Bes' ren with his sheut. Anubis dances with her, but Shu arrives and takes Anubis away, banning him from seeing Sadie again as he has grown too close to her.
While Carter and Zia head out with the ghost of the evil magician Setne to find and capture Apophis' sheut, Sadie sets out with Walt to find Bes' sheut. Over the journey, the two become closer and Walt tries to tell her something about his nearing death, amused when Sadie thinks its that Anubis will help him cross over. The two kiss and eventually reach the ruins where Bes' sheut is and are forced to participate in a hunt by the goddess Neith. Sadie defeats Neith through trickery and realizes to her shock that Walt is following the Path of Anubis (a Path that has never been followed before,) due to the powers he displays and his friendship with the god. Anubis himself arrives in defiance of his ban on seeing Sadie and asks Walt if he agrees to what they planned as it's their last chance due to Walt being near death. Walt agrees and both he and Anubis express that they don't want to leave Sadie, confusing her. Walt, using the last of his energy, binds Bes' sheut to a shabti, teaching Sadie the spell at the same to time so she can do it to Apophis as he won't live long enough to do it. During this, Anubis comforts Sadie as Walt is so close to death and explains the ban is due to him having no mortal form to interact with her in. Following Walt's directions, Sadie casts the reverse of an execration spell on the sheut returning it to Bes and restoring him to normal. Walt dies and when Sadie looks for Anubis, he is gone too. To her shock, Walt comes back to life and creates a portal to Carter, warning her that Setne has betrayed them and that getting rid of Apophis will simply be a matter of casting an execration spell on his sheut in his presence. Confused by his return and Anubis' disappearance, Sadie looks closer at Walt through the Duat and finally understands his and Anubis' plan: Anubis has taken Walt as a host and they have merged, with the god keeping Walt alive. Confused by the fact that both guys she loves are in the same body, Sadie runs through the portal they created.
Sadie arrives at Carter and Zia in time to save them from Setne and rebinds him and frees her brother and Zia. She then captures Apophis' sheut using the spell Walt taught her, but is soon trapped by an army of demons called for by the sheut. However, to her relief, an army of senile gods from the House of Rest (including Tawaret and the restored Bes) arrive and save them. Bes transports them to the shore of the river where they are picked up by Ra on his boat. Sadie watches as Ra takes Zia as a host and is reborn and shares her confusion over her feelings with Carter.
Upon return to the First Nome, Sadie welcomes Isis back into her body while Carter does the same with Horus, and the siblings join the battle against the rebel magicians, trying to convince them that their leaders Sarah Jacobi and Kwai are working with Apophis and that hosting a god is not a bad thing. When Sadie is nearly killed, Walt/Anubis steps in to protect her, both swearing to do so in the future, impressing Sadie and making her feel safe. Walt/Anubis dispatches Sarah and Kwai, but Kwai, possessed by Apophis, tries to bring the Hall of Ages down on them and Sadie uses Ma'at to stop it. The rebels change sides and Sadie watches proudly as her brother takes his rightful place as Pharaoh of the House of Life.
With the other gods and magicians, Sadie battles Apophis and watches as Ra is swallowed. As the other gods distract Apophis, Sadie, drawing on both her own and Isis' power while Carter does the same with Horus, casts the execration spell on Apophis' sheut, finally destroying him. Ra and Zia emerge unharmed, but Isis and the other gods leave the Earth as a result.
After the victory, Sadie visits the Land of the Dead with Carter and speaks to her mother who helps her sort out her feelings for Walt/Anubis. Ruby reveals to Sadie that Anubis will be allowed to stay on Earth as he has Walt as his permanent host and that it will be good for both as they will finally get to live a real life which was denied to them before. Ruby also helps her realize that she now has the chance to love both at once without having to pick one which is good too. When Bast reveals that she has to leave Earth with the other gods, Sadie is sad to see her go and says a sad goodbye to her.
In the end, Walt/Anubis visit Sadie and she decides to follow her mother's advice on the subject and starts a relationship with both of them and dances with them on the rooftop of Brooklyn House.
The Son of Sobek
Even though she doesn't make an appearance, she is mentioned several times by Carter.
The Staff of Serapis
After a dog statue comes to life while Cleo is examining it and flees Brooklyn House, Sadie chases it down, eventually arriving at the High Street Station where she finds Annabeth Chase on a subway train battling a two-headed monster. Sadie blasts the dog monster into the train and boards it where she and Annabeth briefly assess each other before Annabeth tells her to stop the dog monster from reaching the other monster. While Sadie is initially successful, the dog monster throws her off and the other one sends out a wave of energy that derails the train. Sadie is able to pull Annabeth to safety and capture the dog monster, but the other one gets away.
Sadie is able to heal Annabeth's injuries with a healing potion Jaz gave her and the two explain their respective histories. Sadie is shocked to learn that Carter had fought a crocodile monster with Annabeth's boyfriend a few weeks before as Carter had mentioned the fight, but not the person he fought with.
The two realize that the dog monster is actually a third piece of the two-headed monster and that it is trying to merge with its other part. Annabeth figures out that the monster is actually a scepter for a god who she can't remember, the name of whom is both Greek and Egyptian. Sadie realizes the god is from Alexandria, the capital of Egypt when the Greeks ruled, and they realize the monster is trying to reunite with its master.
The dog monster breaks free and heads for a derelict apartment building that is surrounded by a storm that Sadie can only see through the Duat. After using a paste to show Annabeth what she sees, the two head to the building where they find the god, Serapis, cannibalizing the building to build something. As the staff monster starts to make its way up the maelstrom to Serapis, Sadie uses her staff and N'dah to give Annabeth a shield and orders her to distract Serapis while she stops the staff from reaching him. Sadie pulls out one of Walt's camel amulets, turns into a kite and flies into the maelstrom while also flying through the Duat to protect herself.
After the maelstrom freezes due to Annabeth getting Serapis' attention, Sadie drops the amulet on the staff and activates it, causing the camel to pin the staff to the floor below. As Annabeth distracts Serapis, Sadie prepares a protective circle and a binding spell but is shocked to learn that Setne is behind Serapis' awakening. Eventually, Sadie uses her tyet necklace to bind Serapis and tries to name him with the power of Isis, but he breaks free easily and crushes her ha-di spell with ease. Serapis reveals that Isis used to be his wife and he intends to use Sadie to draw her into the world so he can bind her to his servitude again while he destroys the rest of the gods. As he turns his staff on Sadie, causing her great pain, Annabeth distracts Serapis with a piece of plywood to the face, breaking his hold over her. Sadie uses two suh-fah spells to collapse the building on Serapis but nearly burns up from using so much magic and has to be carried to safety by Annabeth.
As the two try to figure out what to do, Annabeth discovers her magical Yankees cap has returned and teaches Sadie some Greek to confuse Serapis while she tries to destroy the dog's head on his staff. Sadie pretends to cast a death link on Serapis with a mixture of Greek, Egyptian and English magic words and distracts him as Annabeth works to invisibly reach the staff. Serapis eventually sees through the bluff, but Annabeth is able to destroy the dog's head on his staff, representing his future and with his future destroyed, so is Serapis. Recovering from the ordeal, Sadie's injuries are healed by a square of ambrosia and she explains Setne's history to Annabeth. The two realize that Setne set the whole thing up as a test of his new hybrid Greek-Egyptian magic and their capabilities and is going after the crown of Ptolemy to become a god. Both agree to look for the crown from their sides and exchange phone numbers to keep in touch before going their separate ways.
The Crown of Ptolemy
Sadie and her brother arrive on governor's island after Setne absorbs Wadjet's essence. They predict that he headed to the southern part of the island. They formulate a plan involving combining Greek and Egyptian magic to stop Setne. The four managed to stop him from absorbing Nekbet but he still gets the crown. The four then make a plan involving Percy hosting the vulture goddess while Annabeth and the Kanes perform the spell. Sadie gives Annabeth her secret name so she can temporarily become an Egyptian magician. They manage to trap Setne in a snow globe. The four have lunch before the Kanes take the crown and Setne with them. Carter and Sadie transform into a falcon and kite respectively and fly off.
