He is the MVP of the future's hottest sport.

In the year 2502, sex is a spectator sport, and Brian Byrne is its undisputed champion. He plays with a passion for the game, never for the woman. So why does he feel burned out, used up, and in need of a vacation? A few weeks in a simpler time where he doesn't have to think about sex sounds great.

She wants a perfect night of pleasure.

Ally O'Neill is having a career crisis. She is the best-selling author of a series on how to be the perfect wife. She is also recently divorced, so her perfect-wife theory obviously needs fine-tuning. Her publisher now wants Ally to write about a night of sexual pleasure from a single woman's perspective. What does she know about sex and today's single woman? Nothing. Ally requires a consultant with sex-god credentials.

Ally and Brian meet in the present beside the ruins of an Irish castle. And in a world where no one has ever heard of the Testosterone Titans, Brian is about to discover that scoring is a lot less fun than falling in love.
