The Book The Witchcraft of Thorns by Margaret Rogerson

All wizards are evil. Elizabeth has known this truth for as long as she can remember. She had grown up in one of the Great Libraries of Ostermere, among the works of sorcery—dangerous magical grimoires that whisper on shelves and rattle iron chains. One careless move and the grimoire would turn into a deadly monster of ink and leather.

When a sabotage unleashes the Library's most sinister grimoire, Elizabeth is framed for the crime. Orphaned, with no connections or support, she can only turn to her archenemy, the sorcerer Nathaniel Thorne, and his demonic servant for help in escaping and unraveling a centuries-old conspiracy.
