A grieving mother gets the shock of her life in this propulsive thriller from the bestselling author of Reese's Book Club pick The Last Mrs. Parrish.

No parent should ever have to face the loss of their child . . .

A year after the tragic death of her four-year-old son, Charlotte Fleming is sleepwalking through life, trapped in a spiral of devastating grief. Then, she sees something online that jolts her awake: her son, Sebastion, alive and well . . . in a stranger's social media post.

Charlotte desperately wants to believe that what she sees is real, that her son is out there somewhere waiting to be brought home. After all, Sebastion's body was never recovered from the accident that supposedly killed him. But what horrific circumstances could have led him to another child's birthday party halfway across the country?

Frantic to find out the truth, Charlotte obsessively looks for any indication the accident that took her son from her was not what it seemed. As she bypasses the police and uncovers red flag after red flag, she starts to suspect that something—or someone—nefarious is at play.

Charlotte's relationships with her husband and preteen daughter were already hanging by a thread, and now it's starting to feel like her sanity is too. But someone has abducted her son; she knows it. And she'll stop at nothing to get him back.
