Ever since Steph’s husband walked out after a thirty-year marriage, home hasn’t felt like a safe haven. Her daughter Bea thinks she’s imagining things. But Steph knows that the noises in the night, the open windows she knows she left closed, the strange smell in the kitchen – none of it feels right.

Then her house is broken into, and a young man named Noah helps her fix the front window. He’s fallen on hard times and Steph impulsively offers him a place to stay. At least if he is there, she won’t be home alone.

Before long Noah is living in Bea’s old bedroom, paying rent, and getting his life back on track. Steph’s ex-husband and Bea are furious. But Steph feels secure at last.

Until the strange things start happening once more.

Until it becomes clear someone will stop at nothing to make her never, ever feel safe again.

The most twisty and unputdownable thriller of the year – perfect for fans of Lisa Jewell, Mark Edwards and Gone Girl.
