"Until that moment, I hadn't realized how much I'd been needing to meet someone I might be able to say everything to."

They met at a party.  It was hate at first sight.  Ruth was far too beautiful, too flamboyant.  Not at all Ann's kind of person.  Until a chance encounter in the bathroom led to an alliance of souls.  Soon they were sharing hankies during the late showing of "Sophie's Choice," wolfing down sundaes sodden with whipped cream, telling truths of marriage, mortality, and love, secure in a kind of intimacy no man could ever know.  Only best friends understand devil's food cake for breakfast when nothing else will do.  After years of shared secrets, guilty pleasures, family life and divorce, they face a crisis that redefines the meaning of friendship and unconditional love.
