Neighbors Betsy Callison and Kat Ellis were oil and water when they met thirty-five years ago. Betsy was a prim, neat freak, Republican wife, and Kat was a wild, irreverent, hippie Democrat. But they soon discover common ground that creates a bond that lasts for decades. Until Betsy's husband leaves her for his secretary, then comes sniffing back around two years later and convinces newly widowed Kat to marry him! Not that Betsy wants him back, but it’s hard to move on when the newlyweds are flaunting their love right across the street. But there’s trouble brewing in Paradise, and no one knows philandering Greg better than his ex-wife Betsy. Can Betsy get involved in her best friend's marriage—even if it means helping her wife-in-law figure out the same man she shared a bed with for thirty years?
