3Morgan Thompson likes her life just fine. She has a tight-knit family, two opinionated cats, and her job as office manager for her brother Perry's medical practice. Perry's an eligible bachelor, but his divorce left him gun-shy, so Morgan has fun tweaking his responses to potential dates online, using her affinity for words to make him sound impressive. When new pharmaceutical rep Zoe Blake walks into his office, though, he's smitten, and he needs Morgan more than ever.

Zoe is beautiful and a little mysterious and doesn't seem terribly interested in Perry. Morgan decides she'll need to get to know Zoe before she plays matchmaker. But soon, she's talking books and movies and writing to her as Perry, and the more she knows, the more she wants to know, until she begins to wonder: Is she wooing Zoe for her brother? Or for herself?
