Flawless by Alyson Reynolds

Book 4 in The Relentless series

Emerald Carter Davis is a hot mess. After her divorce from her high school sweetheart, she thought that starting over with an amazing job in New York City would be the best medicine. And it probably was, until she found out that her ex never filed the divorce papers, which makes the fact that she’s dating one of the most eligible bachelors in NYC a problem.
Mason Davis was always supposed to be her future, but he wrecked her asking for the divorce ten days after they got married. Adam Parker is a wildly successful doctor who has a heart of gold and was there for her when she needed it most. Now Emmy has to choose between her past and her present, and it might just be the hardest decision of her life.

A beautiful writing with real emotion. – Amazon Reviewer
