What's an attractive, successful, all-around-together girl to do when she's dumped at 65 miles per hour on the way to a romantic getaway? If you're Deneen Wilkerson, you retreat to your mother's suburban home in St. Louis for a solitary orgy of snacks, talk shows and mental hygiene. Deneen's crash--and her wildly funny, improbable rebirth--is the basis of this new novel by the acclaimed author of "Somebody Else's Mama" and "Live at Five."
