About

The heart-stopping second novel from the author of Nightwatching, in which a father-son ski weekend becomes a desperate fight for survival

At twelve years old, Zach admires his father almost as much as he fears him. When Bram takes him on a father-son ski trip in the Colorado backcountry with a few select others, Zach feels brave, cautiously optimistic-his mother taught him the ways of the mountain, and the hushed whiteness should quiet Bram's complaints, his temper.

But Zach knows his father well enough to always be on high alert: to the shifting dynamics inside the cabin, to his father's every move, to what lies beyond the warmth of the fireplace. Because something is out there, on the mountain. Something that's killing animals and picking them clean.

And when the trip takes a turn for the worse, Zach fears he's in more danger than he realized. He'll have to rely on his own survival skills if he hopes to make it home alive-but will that be enough? Praise for Nightwatching:

"Phenomenal. . . thrilling."

-Jimmy Fallon

"[Nightwatching] guarantees you will stay up, as I did, way past bedtime, tearing through pages to find out what happens, or you'll be too petrified to sleep, or maybe both."

-Mary Louise Kelly, NPR

"Horror meets thriller in this pulse-pounding locked-room suspense, playing off the dread (and claustrophobia) of being trapped in your home with an intruder. . . Sierra manages to integrate complex ideas about perception, trauma, guilt, and women's autonomy...without once loosening her grip on the reader's nerves."

-Elle

"How many of us have had the experience of hearing an old house creak in the night and wondering if it was something more? That uneasiness becomes terror in Sierra's riveting debut. . . . What happens next falls between horror and suspense, landing with almost unbearable intensity. . . Nightwatching [is] among the best debuts I've read in years."

-LA Times

"[Nightwatching] truly terrified me. . . this was literally catnip for my intrusive thoughts. My heart never stopped racing."

-USA Today

"The reader is thrust into a scenario of unadulterated fear in Tracy Sierra's stellar debut. . . To describe this novel as nightmarish contrasts with the vividness of this night, as Sierra escorts the reader beyond metaphor: Is it a nightmare if it's real? Nightwatching is a terrifying cat-and-mouse thriller in which the creak on the stairs is an overture to a fight for survival."

-Washington Post

"Nightwatching is one of those reads I devour: a thrilling mystery with an actual message and larger societal commentary contained within. . . Sierra's plot is propulsive and is literally heart-pounding. . . Along the way, she raises important questions about who gets to be a victim and how hard it is for women to be believed. It will enrage you, it will scare you, and it will definitely make you want to discuss it."

-Glamour

"Nightwatching grows in stature and becomes not just a nerve-shredding page-turner but also an ingenious guessing game and an absorbing account of a woman's struggle to make her voice heard."

-Minneapolis StarTribune

"The extreme tension . . . triumphs in a gripping and convincing finale. Not for the faint-hearted."

-The Daily Mail



"So terrifying that it can easily be considered horror-adjacent. . . The intense plunge into the main character's traumatic experience feels incredibly real and immediate, and the suspense doesn't let up until the last moments of the novel."

-BookPage

"Tracy Sierra has done the impossible: changed my mind about the home invasion thriller. . . Gripping."

-CrimeReads

"This is an intelligent, excoriating and almost unbearably tense look at what can happen when men choose to assume that a woman is hysterical rather than taking her seriously."

-The Guardian (London)



"The most gripping thriller I have ever read.
