The living cannot be allowed to infect the dead. Adam Binder has lost what matters most to him. Having finally learned the true identity of the warlock preying on his family, what was supposed to be a final confrontation with the fiend instead became a trap that sent Adam's beloved Vicente into the realm of the dead, where none living are meant to be. Bound by debt, oath, and love, Adam blazes his own trail into the underworld to get Vicente back, and to end the threat of the warlock once and for all. But the road to hell is paved with far more than good intentions. Demons are hungry, and ghosts are relentless, and what awaits Adam in the underworld is nothing he is prepared to face. If that weren't enough, Adam has one more thing he must do if he and Vicente are to return to the world of the living: find the lost heart of Death herself.
