"A gorgeous exploration of family, secrets, and love." —Teen Vogue   From the bestselling author of the beloved Sisterhood of the Traveling Pants series, comes a “must-read” (PopCrush) novel about two teenagers who have never met but share the same room on alternating weeks during an unforgettable summer. Previously published as The Whole Thing Together. 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?   "A gorgeously written novel on love, loss, and family." —Nicola Yoon, #1 New York Times bestselling author
