He made one promise. She was the one woman who could make him break it.

Dean has spent eleven years being the dependable one.

The loyal friend. The man everyone trusts. The one who never crosses the line.

So when his best friend asks him to help his newly divorced ex-wife clear out the lake house, Dean says yes without hesitation. It's just one weekend. A favor for the man who's been like a brother for half his life.

He never expected Mara.

He never expected late nights surrounded by the ruins of a marriage, quiet conversations that feel more intimate than they should, or the impossible realization that the woman he's spent years pretending not to love has been hiding the same secret.

Giving in would cost him everything.

His oldest friendship.

His reputation.

The life he's spent years building around doing the right thing.

Because some promises are meant to be kept.

And some women are worth breaking them for.

My Best Friend's Ex is a scorching, male-POV standalone romance filled with forbidden attraction, emotional tension, explicit love scenes, and a guaranteed happily ever after.
