Purgatory should have been a safe haven for souls that belong neither in Heaven nor Hell, but instead John finds himself in a corrupt prison, one bereft of freedom or pleasure. Along with his decedent friend Dante, John makes a brave escape, only to fall straight down to Hell and into the arms of Rimmon, a handsome incubus. John is soon recruited as Hell's ambassador, visiting the afterlife realms of other cultures to enlist an army strong enough to stand against Heaven. As interesting as his new job is, John's mind keeps returning to Purgatory and the souls still trapped there. Somehow John must stop a war he doesn't believe in and liberate Purgatory, all while desperately trying to attract the attention of an incubus whose heart belongs to another.
