Everyone says Lauren Tranter is exhausted, that she needs rest. And they’re right; with newborn twins, Morgan and Riley, she’s never been more tired in her life. But she knows what she saw: that night, in her hospital room, a woman tried to take her babies and replace them with her own ... creatures. Yet when the police arrived, they saw no one. Everyone, from her doctor to her husband, thinks she’s imagining things.

A month passes. And one bright summer morning, the babies disappear from Lauren’s side in a park. But when they’re found, something is different about them. The infants look like Morgan and Riley?to everyone else. But to Lauren, something is off. As everyone around her celebrates their return, Lauren begins to scream, These are not my babies.

Determined to bring her true infant sons home, Lauren will risk the unthinkable. But if she’s wrong about what she saw ... she’ll be making the biggest mistake of her life.
