Serena Holly has a mission. Help her best friend, Keith, find the love of his life before the summer is over.
She and Keith have been friends since they were in school together, and nothing has changed in all these years. After getting through a messy divorce, Serena is now perfectly happy in life with her daughter, her friends, and her job as a high school teacher, but she's afraid that Keith might be lonely. He wants to start a family, and he can't do it until he falls in love. So Serena is going to help him find the right woman, and she's going to ignore all the inappropriate flutters of attraction she starts to feel for him.
Keith Howell has been trying for years not to hope for more than friendship from Serena, so he agrees to her plan to spend the whole summer fixing him up. He does want someone to love. Only he wants her to be Serena. But she's finally gotten to a good place after a difficult marriage, and she doesn't want anything to disturb the life she's made for her and her daughter—especially something as risky as changing the nature of their friendship. But he can't help the way he feels about her, and he won't necessarily be able to stop himself from acting on it.
Serena might think she knows what's best for him, but now Keith has a mission too.
