There’s someone at your front door – should you let them in? Find out in a riveting new psychological thriller from global sensation and #1 Sunday Times bestselling author of The Housemaid.
Who knows what the storm will blow in… Casey's cabin in the wilderness is not built for a hurricane.
Her roof shakes, the lights flicker, and the tree outside her front door sways ominously in the wind.
But she's a lot more worried about the girl she discovers lurking outside her kitchen window.
She’s young.
She’s alone.
And she’s covered in blood.
