In an underworld ruled jointly by a vampire prince, a wolf clan heir, and a human mafia godfather, debt-ridden dropout Elliot is nothing more than an insignificant casino bartender—until clues about his mother's bizarre death point to all three factions, forcing him into a deadly game. Vampire Dante wants him as an eternal treasure; wolf Rafe claims him as a forbidden possession through violent protection; arms dealer Luca lures him with freedom into a soul contract. Elliot plays along while secretly gathering evidence among the three monsters, determined to find his mother's killer and reclaim full dominion over his own body—even if it means setting all three hells ablaze.
