Penny Albright has burned night after night to keep her soul free of Malin's contract. Now, she's at the stake again, and this time, it's her freewill about to burn. As the ashes settle over the temple inferno, Halstett faces the Samhain ball and attendance is mandatory​. At midnight, when the veil between Life and Death is at its thinnest, the Warden means to destroy magic and the witches who wield it. With her family missing and her friends lost, Penny turns to the Sorcerer chained on the mysterious ninth floor of the library for aid.

He offers a deal: a legion to fight the Warden in exchange for her blood.

Just one drop into the eternal fires will end the Warden's reign and set the Sorcerer free. But as Alice's visions fail and Malin fights the lifeline bond Penny forged to save him, one drop of blood might destroy them all. And with the Warden using Penny's circle of Resistance witch friends as a shield, Penny is forced to choose between the friends she loves and the covens she belongs to.

A single night might spark a war that will tear the world--or Penny's heart--apart.​
