When I wake up with the sun in my eyes the morning after my daughter’s birthday party， I know something is very wrong。 I go straight to her room but feel a surge of panic when I see an empty bed。 Downstairs everything is totally quiet， and the front door is locked。 Why didn’t I hear her scream？ Who took our little girl？

My husband says I’ve been struggling since Skylar was born and that sometimes I forget things。 But I remember every moment of my daughter’s party—including him locking the door after our family and friends left。 Yes， we both had a drink and I slept heavily but I know I would have heard my child cry。 A good mother always does。

My therapist says I need to stand up for myself。 She wants me to confront my husband about the woman I heard him talking to the other night when he thought I was asleep。 And about the child’s toy that I found that does not belong to Skylar。 Is he hiding something？

But as the hours race by I soon realize I was totally wrong about everything that happened that night。 I thought I’d put my past behind me long ago but I was wrong。 All I know is this: I’ll do whatever it takes to save my child。

Will you believe me？

A heart-pounding， unbelievably twisty psychological thriller that will have you sleeping with the light on！ Fans of Gone Girl， Behind Closed Doors and The Stepdaughter will be utterly gripped。
