Chilling Adventures of Sabrina: Daughter of Chaos by Sarah Rees Brennan

Sabrina Spellman thought choosing between her mortal life and her witch heritage was the hardest decision she would ever make. But after signing her name in the Book of the Beast, chaos begins to follow her everywhere. The coven is restless, dark omens cloud the skies, and Sabrina’s own powers are growing beyond her control. When her mortal friends begin suffering strange accidents and a mysterious demon targets her loved ones, Sabrina must face the dark truth about her destiny. Torn between loyalty, love, and an ancient evil rising in Greendale, she learns that every choice carries a price — and some debts can only be paid in blood.
