Katie Kim has her life on track. She’s just been promoted, she has a sweet, new boyfriend, and she’s finally recovered from the heartbreak of her past. All is well until the day Tyler June walks into her office; he’s her new intern, and he’s also her ex-fiancé.

To make matters worse, Katie hasn’t seen Tyler since she caused the car accident that stole his memory five years ago, and his parents pushed her out of his life.

Tyler has no idea who Katie is; to him, it’s as if she never existed. Katie, on the other hand, has an entire relationship’s worth of memories and unresolved feelings trapped inside of her.

As she’s reminded why she fell in love with Tyler the first time, should she resist him out of guilt for her actions, or out of loyalty to the new man she loves? And when Tyler finds out who she really is, will he even love her at all?
