NEVER READ. What if your most basic beliefs about your life were suddenly revealed to be a lie? As the fact checker for a popular magazine, Gabby DiMarco believes in absolute, verifiable Truths—until they throw the facts of her own life into question. The genealogy test she took as research for an article has yielded a baffling result: Gabby has a sister—one who’s been desperately trying to find her. Except, as Gabby’s beloved parents would confirm if they were still alive, that’s impossible. Isabella Ruiz can still picture the face of her baby sister, who disappeared from the streets of San Juan twenty-five years ago. Isabella, an artist, has fought hard for the stable home and loving marriage she has today—yet the longing to find Marianna has never left. At last, she’s found a match, and Gabby has agreed to come to Puerto Rico. But Gabby, as defensive and cautious as Isabella is impulsive, offers no happy reunion. She insists there’s been a mistake. And Isabella realizes that even if this woman is her sister, she may not want to be. With nothing—or perhaps so much—in common, Gabby and Isabella set out to find the truth, though it means risking everything they’ve known for an uncertain future—and a past that harbors yet more surprises . . .
