Sixteen-year-old Jack Ironwood knew exactly what he wanted. Until he got it. Jack was content to stay unnoticed by pretty and popular track star, Natalie Segetich, until her best friend Emma disappears. Natalie swears something took Emma, and though most people write Natalie off as traumatized and confused, Jack is a soulshifter and he knows the human-stealing Enuuki—hell's messengers—are real. As a soulshifter, Jack can cross into the underworld so he sees Emma's rescue as an opportunity to prove himself a valuable member of his transcendental sect—and a way to secure a future otherwise out of his reach. Although he needs Natalie's help to prepare for the mission, Jack intends to go to the underworld alone. But as a viable plan takes shape, it's clear the best chance of success means Natalie must accompany him. On the eve of the quest, when Jack is promised the hand of a respected elder's daughter—a dream come true—he realizes he's no longer sure what he wants. But it's too late to back out, not with the sect and Natalie counting on him. Pursued by the dark lord's henchmen and ghastly mutant creatures, Jack and Natalie struggle to come out ahead in a battle and barter for souls. In the end, Jack will have to decide his own fate, because nothing short of a deal with the devil will get all three of them out of hell alive.
