Daughter of chaos - Sarah Rees Brennan

Half-witch, half-mortal sixteen-year-old Sabrina Spellman
has made her choice: she's embraced her dark side and her witchy
roots. Now her power is growing daily ... but will it come at
too high a price?

Sabrina Spellman has just made the hardest decision of her life:
she's leaving behind her beloved friends at Baxter High. Now it's
time to follow the path of night and find her way among the witches
and warlocks at the Academy of Unseen Arts.

Sabrina has always been good at the school thing, but now she
has a whole new world to navigate. Her power is growing daily, but
it comes with a high price. She must always remember her new allegiances
and the cost they have on her friends ... and on herself.

And then there's her new classmates. Prudence, Dorcas and Agatha
are friends, kind of, but can Sabrina trust them? And what about
Nick Scratch? He's as charming as ever, but will his feelings
for Sabrina last?

Based on the hit Netflix show, this original YA novel tells
an all-new, original story about Sabrina.
