Five years ago, Tessa Marshall turned her back on everything she once knew. She left behind her friends and family hoping they would be better off without her in the way. Now, after being diagnosed with dissociative identity disorder and determined to set her life straight, she is going back. She doesn't expect her best friend growing up, and the only man she has ever loved, to be waiting for her. Charlie Mackenzie never knew the real reasons why Tessa left, but because of the promises he swore to keep, he feels responsible. He has spent the last five years staying distracted, and trying not to chase after her and drag her back to him. Now that she is finally back, he won't allow her to push him away without knowing how he has felt about her all along. The only problem? He's not just dealing with Tessa anymore. The two of them must decide if their love is worth fighting for and Tess has to learn to just let go, because Charlie won't let her go. He won't let any one of her go.
