The Sweetheart Deal by Mary J. Williams

The boy next door is now the Sexiest Man Alive.
The same boy who shared your first kiss—
Then broke your heart into a million pieces.
Sometimes life just sucks.
Bryn Larson couldn’t catch a break. On the same day she loses her job, she gets an offer she can’t refuse—from the last man she ever wanted to see again.
Declan Young once worshiped the ground on which Bryn Larson floated through life. When he discovered she used him, he left town and never looked back.
Twelve years later, Declan is a movie star and Bryn is barely getting by. When a friend asks him to give her a job, neither is thrilled at the idea. When Bryn moves in, sparks fly.
First love. Forced cohabitation. Uncontrollable sexual attraction.
What could possibly go wrong?
