Everyone has secrets. Even best friends. Mo Fitzgerald knows about secrets. But when she witnesses her best friend's murder, she discovers Verity was hiding things she never could have guessed. To find the answers she needs and the vengeance she craves, Mo—quiet, ordinary, unmagical Mo—will have to enter a world of raw magic and shifting alliances. And she'll have to choose between two very different, equally dangerous guys—protective, duty-bound Colin and brash, mysterious Luc. One wants to save her, one wants to claim her. Which would you choose?

Constance started to keen as the air around us began to thrash and twist, the caustic scent of ozone burning my nose. As I watched, her dark gold hair began to lift and kink into knots. “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.

“I beat you. Twice. No magic, and I still beat you. And that was when I didn’t know what I was doing.” I smiled, cold as the winter sky outside. “Imagine what I’m capable of now.” Mo Fitzgerald has made her choice: A life in Chicago. A future with Colin. To leave behind the enigmatic Luc and the world of the Arcs. But every decision she’s made, from avenging her best friend’s death to protecting the people she loves, has come at a terrible price. As her father returns from prison and the Seraphim regroup, war breaks out in both her worlds. And Mo isn’t the only one with secrets to hide and choices to make. The more she struggles to keep her magic and mortal lives separate, the deadlier the consequences. In the end, Mo must risk everything – her life, her heart, her future—or lose it all.
