The Husbands by Holly Gramazio

Lauren has a big problem. She comes home from a night of partying to find her husband at home--but she's not married. She soon discovers that something bizarre is happening in her attic. It is able to produce an endless supply of husbands. If she doesn't like the husband she's been given, she can just send him up in the attic and he disappears and is replaced with a new one, each having his own history with her. Uncovering the backstory of her life with each current husband can be exhausting at times. In addition, even though time is moving forward, Lauren sometimes finds her close friends' and family's lives have changed too. The Husbands is an interesting and original look at one woman's journey to find a life that works for her.
