'Mollie’s missing.' As I look at my husband, I struggle to take in his words. For years, I’ve been so focused on our son, who needed me to care for him. I’ve sacrificed so much to make him feel safe. But have I put my own daughter’s life in danger?

When we discovered we were having twins, a boy and a girl, I couldn’t believe our luck. Within months we would have the perfect family we’d always dreamed of.

The first few years were so happy. Our house was chaotic but full of love, just as it should be. But as the years passed, we had to acknowledge that our son Ben needed a lot more support than Mollie. I had no choice but to put his needs first. I wanted him to have the best life possible. But it came at a devastating cost.

Now, Mollie is missing. Clasping my husband’s hands for the first time in years, we start to piece together any reason for why she disappeared. Mollie was a straight-A student, a perfect daughter, a loyal friend. As my husband looks at me in fear, I’m forced to confront a truth I have spent years trying to hide.

They say it is impossible to choose a favorite child. But years ago, during a house fire I had to do just that. I had to push one child to safety ahead of the other. I chose my son. Now I’m forced to question whether my dear daughter has always remembered what I did. Am I the real reason she disappeared? And will I ever see her again?

An absolutely heartbreaking and tear-jerking story about the strength of a mother’s love. Perfect for fans of Jodi Picoult, Kate Hewitt and Diane Chamberlain.
