I received an ARC of this book from NetGalley in exchange for my unbiased opinion. 
 Gwen is a nurse in NYC during WWII. Her roommate, Alice, is married to a man in the army and has a baby. One day, Alice tells Gwen she is leaving and leaves the baby, Mary, behind with Gwen. Gwen comes to love Mary as her own child. Then, on V-J Day, Gwen comes home to discover Mary's father, John, waiting on her doorstep. First, John goes out to California to try to find Alice. When he is unable to do that, he comes back to New York and works with Gwen to get to know his daughter and how to be a parent instead of just ripping Mary away from the only parent she remembers. As they get to know each other, they fall in love. 
 This was a sweet story. I liked the side story of Gwen's new roommate, Dot, and her husband, Dennis. While theirs was not a happy story, the PTSD Dennis experienced was something that affected a lot of men coming home from World War II. I recommend this book to anyone who enjoys charming, clean romances.
