In his desperation to find a date in time for the annual Helloween bash, minor-rank demon Kev summons a coworker he once hooked up with. But when the smoke and sulfur clears, it isn’t demon Ira standing in the ring, but a very perplexed, very human mortal named Archer.

Archer is cute, confused, and willing to consider going as Kev's date ... for a price. Turns out this isn't the first time Archer's met a demon, and he wants his soul back.
