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.

Thorn is paying a hefty price for saving Nightworld. Not only has the darkness come calling, but so has her coven… After catching the attention of witch trackers, Thorn brokers a deal with the devil again and is thrown into another supernatural investigation with the irresistible—and infuriating—fae prince. Dead bodies are turning up at Shade, and there’s no doubt that vampires are responsible. But Vampire King Hugo is making more than a play for territory this time. While a new danger lurks in Chicago, the shadows creeping through Thorn grow stronger. The more she uses her death powers, the deeper she sinks into madness. As secrets and betrayal threaten to tear the partners apart, Caleb and Thorn are left at the mercy of enemies. If she can’t regain control of the death raker, not only will Thorn’s soul be forfeit, but Nightworld could become a true hell on Earth.
