Memories of You by Jess Mastorakos

Sometimes your soul remembers what your mind has forgetten…

US Marine Travis Brooks is ecstatic when his wife wakes up in the hospital after a horrific car accident. His joy quickly fades when he discovers that she’s suffering from post-traumatic amnesia and has an incomplete memory of their relationship. As far as Cat’s concerned, they’re broken up. Not happily married.
Catherine Brooks has no memory of the last ten years. She’s mystified as to why her ex-boyfriend would be sitting vigil at her bedside. The last thing she remembers is breaking up with him right before he left for bootcamp. Now he stands before her as a decorated Marine, rings on both of their fingers, telling her they’re in love.
Travis is willing to do anything to help his wife put the pieces of her memory—and their marriage—back together, whether she likes it or not. He has to. He took a vow to love her in sickness and in health. But will Cat want to fight for their marriage, even though she can’t remember pledging the same vow?
