Can a one-night-stand become a forever love? 

Graduate student Carly Elsen doesn’t do relationships. Abandoned to the foster care system as a child, commitment isn't for her. People just leave anyway. When she has a one-night stand with a sweet, handsome, clean-cut man—definitely not her type—she doesn't need more than his first name. That's a feature, not a bug. So she’s surprised when he turns up in her college library. More surprising? He’s a professor at her college. 

Nate Collingswood, professor of neuropsychology, is a serial monogamist, always dating the perfect woman, the kind he can take home to his successful parents. But choosing Ms. Right always seems to go wrong. Fresh off a broken engagement, a friend suggests he try something different. A one-night-stand with salty, sassy Carly, with her ever-changing hair and sleeves of tattoos, is as different as it gets. He's thrilled when Carly offers to help him make his ex-fiancée jealous by pretending to be in a relationship. 

Carly’s confident and independent. Nate’s not a guy to step outside his comfort zone. So why’s he really sticking around? His idyllic family is so different from her shattered one. When their pretend relationship gets all too real, can Carly trust Nate to stay? A relationship just for fun might turn into love forever.
