When you read as many thrillers as I do, it’s hard to be not to feel as though you’ve read it already. Tracy Sierra’s debut Nightwatching definitely offers a few surprises for discerning readers.

Our unnamed narrator wakes up in the middle of the night to the realization that “There was someone in the house.”

It’s a terrifying notion because she is alone with her two young children and a snowstorm is raging outside. When she steps out of her room to investigate, she sees him at the end of the hall.

He was tall. His arms hung loose and long. His presence had the distantly familiar rancidness of something wrong and rotten she’d tasted before but couldn’t quite place.

All this woman knows is that she needs to keep her children safe. And thus begins a very long night of cat and mouse. The woman knows something about the house that she is quite certain the intruder does not know, and that’s the existence of a secret room. But even that will not guarantee long-term safety, so there are hard decisions to be made.

As they hide, the woman mulls over the details of her marriage, past trauma, and her acrimonious relationship with her father-in-law. These sections were perhaps not as exciting as other parts of the book. This book also has some interesting things to say about trauma and whether or not women are believed. I don’t want to say too much about that, but I have to admit to feeling like I was being gaslit. Is the woman a reliable narrator? Could I trust what I was being told?

While some parts of the book were a tad slow, there were lots of moments when the pages turned themselves and, at the end of the day, I felt like the book really delivered on its promise. Sierra is definitely a writer to keep your eye on.
