A few months into her retirement Mary Alice Roth does not know how to fill her days. At least there's Ellie, who stops by each morning for coffee and whose re-emergence in Mary Alice's life is the one thing soothing the sting of retirement. Mary Alice and Ellie were a pair since the day Ellie moved in next door. That they both were single mothers - Mary Alice widowed, Ellie divorced - with sons the same age was a pleasant coincidence, but they were forever linked when they lost the boys, one right after the other. Years later, the two are working their way back to a comfortable friendship. But when Mary Alice's sister arrives on her doorstep with a staggering piece of news, it jeopardises the careful shell she's built around her life.
