The Seven Deadly Sins. Vices meant to tempt and devastate humanity. Now, they are one man's singular hope for rescuing his sister. Six months ago, Rebecca was abducted-taken in the night by entities that shouldn't exist, and after months of searching for her and no leads, her brother Robert begins to lose faith. Yet, Robert's luck changes when Dez appears. She baits him with knowledge of Rebecca's whereabouts and offers him a partnership. Robert accepts her help and that of her colleagues, two of the current embodiments of the Seven Deadly Sins, beings who were once human but are now gifted powers that stretch beyond infernal or angelic abilities.

Robert finds himself an unknowing participant in a war of biblical proportions, where demons can be allies, angels are the enemies, and the Seven Deadly Sins fight for humanity's freedom. Through it all, Robert must repay a life debt owed to his sister, discover the secrets behind her abduction, and why they have become pawns in a millennia-long battle.
