The Intruder

There's someone at your front door – should you let them in? Find out in a riveting new thriller from global sensation and #1 New York Times bestselling author of The Housemaid, Freida McFadden!

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.

The girl won't explain where she came from, or loosen her grip on the knife in her right hand. And when Casey makes a disturbing discovery in the middle of the night, things take a turn for the worse.

The girl has a dark secret. One she'll kill to keep. And if Casey gets too close to the truth, she may not live to see the morning.

In this taut, deadly tale of survival and desperation, #1 New York Times bestselling author Freida McFadden explores how far one girl will go to save herself.

"The Intruder has all the ingredients of a terrific thriller: A dark and stormy night. An isolated cabin in the woods. A runaway child with a mysterious past. And (of course!) one surprising plot twist after another. With this fast-paced and engrossing novel, Freida McFadden demonstrates (yet again) why she is one of our most popular storytellers. Buckle up, thriller fans!" ― Jason Rekulak, New York Times bestselling author of The Last One at the Wedding

"McFadden has done it again. The Intruder is everything I want in a thriller: bingeworthy from the jump, deeply twisted, and impossible to put down. My smartwatch told me to calm down half a dozen times while reading this book. I did not." ― Noelle W. Ihli, bestselling author of Such Quiet Girls

"A grim yet gleefully gratifying tale of lost innocence and found family...McFadden lulls readers using a seemingly straightforward thriller setup before launching headlong into a series of progressively seismic (and increasingly bonkers) plot twists. The visceral first-person, present-tense narrative alternates perspectives, fostering tension and immediacy while establishing character and engendering empathy. Ella and Anton’s relationship particularly shines." ― Kirkus Reviews

"McFadden brings her usual tight plotting and twists to this massively absorbing work of psychological terror, which will be a winner with her fans and all who enjoy a tense, character-driven read." ― First Clue
