Holly and Gerry are the kind of perfectly happy married couple that others envy. Then, at the age of thirty, Gerry is diagnosed with a terrible illness. Months after Gerry's death, Holly receives a package of letters that he's left for her, instructing her to perform a series of unexpected tasks. With the help of the letters - and her fun, quick-witted girlfriends and a raucously endearing family that smothers, loves, and drives her crazy - Holly wobbles, weaves, and jokes her way toward a new life, even larger than the one that she's been forced to leave behind.
