For centuries Cupid longed to be more than Venus's arrow boy. When he's sent to eliminate "Happily Ever After by Amelia," the matchmaking business threatening Venus's status as the goddess of love, Cupid tries to steal Amelia's methods but accidentally shoots himself with his own arrow and falls in love with her. Amelia doesn't believe in Roman gods and she's certainly not looking for romance. She's too busy perfecting the patented personality profile that's made her Hollywood's favorite matchmaker.

Disguising himself as a financial advisor, Cupid manages to break through Amelia's guarded exterior. As their passion deepens so does Cupid's guilt about deceiving her. His interference causes her business to falter, leads to a sterile spring, and shatters the longstanding peace between the Roman and Greek gods. With the fate of the natural and underworlds at stake, Cupid must decide whether to reveal his true identity and risk losing the chance to live happily ever after with Amelia.
