The Royal Trade — Erin Hayes

Cara thought she was living the fairy tale life. After all, she is engaged to the man of her dreams, who just happens to be the prince of an island nation in the Mediterranean. But when he publicly cheats on her, her life is turned upside down and she doesn't want to come back to reality. Then Eric, her ex-fiancée's brother and a playboy prince himself, offers her the chance to run away from it all. Because he fell for her first. And he's going to prove to her that she fell for the wrong prince.
