"I'm here. It'll be okay." It was the last thing I said before my best friend's little sister went supernova in the second-floor girls' bathroom, taking me with her.

A month ago, Mo Fitzgerald risked her life to stop an ancient prophecy and avenge her best friend's murder. Now, she only wants to keep her loved ones safe. But the magic – and the Chicago Mob – have other plans.

Mysterious, green-eyed Luc is back, asking for help – and a second chance. Colin, her strongest protector, is hiding a shocking secret. And inside Constance, the magic is about to go terribly wrong. Tangled in a web of love and betrayal, Mo must choose between the life she's dreamed of and the one she's destined for.
