Sebastian Stone has a wedding to stop. His best friend's sister is planning to make an epic mistake in six months, but no one else seems to get it.

So when Lainey Morris needs a place to stay in Cleveland for a four-month long research project, Bash offers her his house. As a pro hockey player, he's on the road a lot, but when he's home, he makes his case against her marrying Shane-or anyone else.

She's stubborn and often has her head in a book, but Lainey is also beautiful, funny and sweet. Plenty of men would like to lock her down, but she needs to focus on herself. Take her time. Wait until she's at least thirty.

Bash plans to use logic and reason to persuade Lainey to stay single, but everything falls apart when he finally figures out the truth: he's in love with her. But is it too late to hope she might feel the same?
