For everyone who has received an invitation to their high-school reunion and broken out in a cold, clammy sweat, Berg nails the experience: the dread that morphs into downright fear; the bouts of self-doubt that coalesce into prolonged periods of self-loathing; the internal inventory that comes up short in the bragging-rights column. Of course, there’s just as much potential for life-affirming and life-altering revelations. Glory days can be relived, damaged reputations repaired, lapsed friendships restored, lost loves rekindled. As Dorothy, Pete, Mary Alice, Candy, and Lester consider returning to Clear Springs for their fortieth high-school reunion, each contemplates the chance for redemption and revenge, renewal and retribution. Ultimately, they are then surprised to discover how much they have yet to learn about human nature and their own capacity for joy and forgiveness. Luckily, the zestfully wise Berg is the perfect teacher for such tender lessons of the heart, and her sublimely authentic and winsome characters are apt students. Book groups are clamoring for upbeat yet significant works that are entertaining as well as enlightening; Berg’s latest novel satisfies and succeeds on both counts.
