For Sasha, summer means time at her family's sprawling old house out on Long Island. For Ray, it's the same. Sasha and Ray aren't related--and they've never met--but long ago, before they were born, Sasha's dad and Ray's mom were married. Then came a bitter divorce, remarriages, and a new generation of children. Now, the two families have an arrangement: use the summerhouse at your designated time and never cross paths.
Sasha and Ray do connect, though, by email--joking around, confiding in one another, forming a friendship. They've shared so much already . . . what would happen if they met in real life?
