Chicago obstetrician Mackenzie "Mac" Huntress set her standards for men early on. It's been over twenty years since she fell for a fictional movie heartthrob, and Mac's content to wait for the real version to come along; it's her mother who's not happy with the timeline. So Mac falls back on her lifelong Mom-surviving skill-lying. The latest fabrication: a handsome neurologist named Michael. Pity he's too busy to meet her friends and family. Problem solved. But when Mac's little sister announces her engagement, Mac is expected to introduce her "plus-one" at the wedding, leaving her with only forty days to find a flesh-and-blood stand-in for the imaginary Michael. And the only potential Mr. Right comes with a big hitch. However, it turns out Mac's not the only one bringing secrets to the wedding. With expectations high, and truths to be revealed, Mac's left to find her own happy ending, which isn't as simple as in the movies though it's definitely worth waiting for.
