“Please don’t worry, Ava. Your baby is safe with me. I’m going to take care of her like she’s my own…”

Ever since my daughter Isa was born, I’ve been struggling. I can’t remember anything, and my brain is in a fog. So when my husband Ned suggests we hire a night nanny, I leap at the chance.

As soon as she walks into our home, I feel a wave of relief. I smile at her and notice her eyes are the color of amethysts. A memory flashes across my brain, but before I can grasp it, it’s gone.

But something isn’t right. Ned is acting strangely and every time I ask him why, he tells me I’m being paranoid. But I’ve seen him whispering to our nanny and it makes me nervous. He was the one who wanted to hire her, and now I’m wondering why…

Then my engagement ring goes missing. Ned is furious—it cost a fortune—but I know I haven’t misplaced it. I always hide it in the same place, and no one knows where except him.

But then it gets worse. Our nanny accuses me of leaving my baby face down on her stomach, struggling to breathe. I might be exhausted, but I would never do that. But when I look to Ned for support, I can see he doesn’t believe me.

I feel like an outsider in my own home. Am I going mad, or is someone trying to destroy me?

The totally gripping psychological thriller with twists that will leave you guessing. Perfect for fans of Freida McFadden’s The Housemaid, The Girl on the Train and Colleen Hoover’s Verity.
