Joseph and Isabelle Winters seem to have it all: a grand home in Holt, New York, a trio of radiant daughters, and a sense that they are safe in their affluent corner of America. But when five-year-old Ellie disappears, the fault lines within the family are exposed: Joseph, once a successful businessman, succumbs to his demons; Isabelle retreats into memories of her debutante days in Savannah; and Ellie's bereft sisters grow apart--Madeline reluctantly stays home, while Caroline runs away.
