Alel is a demon, and he is good at lying. The image he wears is a lie—no one can see his wings or barbed tail, nor can they see the horns peeking from a shag of hair salted with strands of white and pale gray. Half-starved, Alel is short and gangly and has lavender freckles dusted across his nose and cheeks. Lust created him along with all other incubi and succubae for one reason—to encourage humans to sin while feeding off of their sexual energy. Anything more than carnal acts is forbidden, but Alel yearns to be kissed, to bury his face in the crook of a lover's neck and hold them until dawn.

When he meets a human named Jackson, who's more interested in snuggling on the couch while watching movies and making out instead of one-night stands, Alel realizes dating Jackson would leave him famished, but he can't resist the temptation.

As their relationship builds, Alel and Jackson explore the boundaries of both sexual and romantic intimacy. The more they're together, the more they fall in love, but Alel knows if another demon ever catches him, he'll be dragged back to hell for breaking taboo.
