Catalina Sanchez and Santiago Castillo have despised each other for years, but the only thing that can save their reputations now is a fake relationship... even if it brings out some very real feelings.

Catalina has one goal and one goal only this season: win her first Grand Slam title and become the number one women's tennis player in the world. At least until she gets caught in a scandal and the only way out of it is to pretend she's dating the man she hates the most: Santiago Castillo. Being the golden boy of tennis, Santi has to uphold a certain image, but his partying and playboy ways are threatening to ruin it, making them the perfect candidates for each other in this ruse.

They have one season to clean up their reputations and achieve their professional goals, but Santi has a personal one at stake, too.

When he discovers why Catalina hates him, what he's done, he vows to do everything in his power to make it up to her, including groveling on his knees if she wishes. Moment by moment of tenderness has Catalina's walls breaking down until she finds herself as drawn to Santiago as she was when they were still kids playing doubles.

The only thing standing in their way is their past and Catalina's fear that somehow they will find a way to ruin what they've so carefully built, just like it happened years prior. Only this time, Santiago is determined to make sure Catalina will never regret giving him a piece of her heart.
