On a midsummer's night Paula Hook lies awake; Mike, her husband of twenty-five years, asleep beside her; her teenage twins, Nick and Kate, sleeping in nearby rooms. The next day, she knows, will redefine all of their lives.Recalling the years before and after her children were born, Paula begins a story that is both a glowing celebration of love possessed and a moving acknowledgment of the secrets on which our very identities rest. Brilliantly distilling half a century into one suspenseful night, Tomorrow is an eloquent meditation on the mystery of happiness.
