Runaway witch Thorn Rosalee has a deadly power. And if she falls into the wrong hands, her soul will pay the ultimate price… After the war among fae and witches, seventeen-year-old Thorn hides in the one place her coven will never find her. Enemy territory. But when the Unseelie King discovers her lethal secret, she’s forced to partner with his son to uncover the culprit behind Chicago’s newest serial killer. Working with Caleb Blackwood turns into a daily battle of wills—one the prince plays dirty to win—and between bloodthirsty vampires, vicious shifters, and sinister demons, their search for answers only leads to more trouble. Fae aren’t the only ones who notice the witch’s hidden talents. And before long, Thorn will have to face the monsters of her past to survive another day in Nightworld.
