From the internationally best-selling author of An Enchantment of Ravens comes a breathtaking fantasy story of magic, power and slow-burning love. This is the perfect story for fans of Cassandra Clare, Leigh Bardugo, Alexandra Bracken and Holly Black!

All sorcerers are evil. Elisabeth has known that as long as she has known anything. Raised as a foundling in one of Austermeer’s Great Libraries, Elisabeth has grown up among the tools of sorcery—magical grimoires that, if provoked, transform into grotesque monsters of ink and leather.

Then an act of sabotage releases the library’s most dangerous grimoire, and Elisabeth is implicated in the crime. With no one to turn to but her sworn enemy, the sorcerer Nathaniel Thorn, she finds herself entangled in a centuries-old conspiracy. Not only could the Great Libraries go up in flames, but the world along with them.

As her alliance with Nathaniel grows stronger, Elisabeth starts to question everything she’s been taught—about sorcerers, about the libraries she loves, even about herself. For Elisabeth has a power she has never guessed, and a future she could never have imagined.
