Dan and Liss are witches. The Black Book granted them that power. Harnessing that power feels good, especially when everything in their lives makes them feel powerless.

During a spell gone wrong, Liss's boyfriend is snatched away by an evil entity and presumed dead. Dan and Liss's friendship dies that night, too. How can they practice magic after the darkness that they conjured?

Months later, Liss discovers that her boyfriend is alive, trapped underground in the grips of an ancient force. She must save him, and she needs Dan and the power of The Black Book to do so. Dan is quickly sucked back into Liss's orbit and pushes away her best friend, Alexa. But Alexa has some big secrets she's hiding and her own unique magical disaster to deal with.

When another teenager disappears, the girls know it's no coincidence. What greedy magic have they awakened? And what does it want with these teens it has stolen?
