From the #1 New York Times bestselling coauthor of The Wife Between Us comes a twisty short story about a chance encounter that tests the boundaries of a mother’s love. Blair Martin’s days rarely vary: she gets up, goes for a run, and then heads to work at a Manhattan literary agency where she nurtures authors through the publishing process. Her nights, spent alone in her too-large apartment, are similarly predictable. Then on an ordinary Wednesday, Blair enters her office building and spies a lost wallet. When Blair tracks down the owner, they arrange for a simple exchange. But the young woman, Maya, seems so vulnerable, much like Blair’s own daughter, Faith, who died tragically just last year, and Blair is unable to simply walk away. Tentatively, Blair takes Maya under her wing. Both women are all too familiar with loss, and they find solace in spending time together. But as their connection deepens, they discover that each of them is harboring secrets much darker than grief.
