Twelve-year-old Zach is cautiously optimistic. His father Bram, whose business is in dire need of cash, has put together a father-son backcountry ski weekend to wine and dine his biggest investors. Schooled in outdoor survival by his mother, Zach is eager to prove himself to the hypercritical Bram. Maybe if Zach shows how useful he is, he can earn his father’s love.
But Zach knows to be on high alert around Bram, and he sees the way the group ignores the increasingly threatening conditions. For the first time in his beloved mountains, he is faced with the unknown, convinced that something watches their cabin from the treeline. Something that leaves behind strange tracks and picks its prey clean.
As the adults recklessly test the limits of the outdoors, Zach worries he might be in even more danger than he realized. Could the men around him prove more violent than the unforgiving weather, and the strange creature lurking in the dark? Zach will have to rely on his wits if he hopes to make it home safely. But he knows all too well that the wilderness can be unpredictable even at the best of times. And at the worst? Deadly.
Warning Signs is a survival thriller unlike anything you’ve read before. It’s intense, unsettling, and has family drama, long-buried secrets, emotional abuse, and morally corrupt adults. The isolated, snowed-in setting (high in the Colorado Rockies) feels increasingly suffocating as the story unfolds. What makes the story feel so original is the child protagonist. You’re inside his head the whole time, watching him piece things together while the adults around him posture, lie, and let their egos take over—and you can’t help but root for him! The story takes place during a father-son backcountry ski weekend filled with toxic alpha-male energy, where it quickly becomes clear the fathers have motives and private agendas for being there. This is Sierra’s second novel, following her hugely popular debut, Nightwatching. While this book is very different, it’s just as gripping—another slow-burn thriller that finds its stride in the second half.
The story follows twelve-year-old Zach Fisher, who’s dragged along on a backcountry ski trip with his father, Bram, and a group of Bram’s business associates. It’s supposed to be a father-son bonding weekend, but it’s really about Bram trying to impress potential investors and their sons—Shane, Russ, Jon, and Dave—along with their quiet guide, Steve. Almost right away, things start to fall apart. Bram’s assistant, Ginny, vanishes, a deadly avalanche hits, and strange signs in the snow suggest they may not be alone out there.
The story is told primarily via a third-person perspective focused on Zach, giving readers access to a child’s view of everything happening around him. But because of his intelligence, intuition, and high self-awareness, his POV feels much older than a typical twelve-year-old’s. The adults—especially Bram and the other fathers—are extremely unlikable. Bram is self-absorbed and more concerned with his own image than his son, while the other men range from arrogant to ignorant, radiating toxic masculinity. Zach’s deep love for his late mother, who taught him real mountain survival skills, is the emotional core of the story and shapes much of his inner dialogue. His longing for his father’s approval conflicts with what he knows to be true, and the flashbacks to his mother help guide him through the very real danger that unfolds.
The pacing is a bit uneven in the first half. Much of it focuses on Zach and his father greeting the others as they arrive, with motives and hidden agendas slowly surfacing through dialogue rather than action scenes. There are also flashbacks woven in of Zach with his mother and sister that add emotional depth but further slow the momentum. If you’re going in expecting immediate thrills and high-stakes wilderness survival, the first half will test your patience. But it pays off in the second half—and once it does, it’s hard to put down! The short and punchy chapters, often ending on cliffhangers, definitely help keep you flipping pages—especially after the avalanche hits and the threat of an unknown predator intensifies. While the twists may feel predictable to seasoned thriller readers, the final confrontation scenes are intense and emotionally charged, and the ending delivers a satisfying sense of justice that lingers!
Overall, Warning Signs is a chilling survival thriller that weaves together natural disaster, psychological tension, and flawed human relationships into a fresh and unsettling narrative. If you go in knowing you’ll need a little patience before the real suspense kicks in—and you appreciate vivid, elevated writing that goes beyond a typical fast-paced thriller—this one is absolutely worth reading! It’s also recommended for anyone who loves wilderness survival stories, slow-burn psychological dread, and snowed-in settings that turn deadly and keep you on edge right up until the end!
Narrator Performance
The audiobook of Warning Signs is read by award-winning narrator Michael Crouch, who’s known for his emotionally charged performances and his ability to fully embody younger protagonists and make them fully authentic and compelling.
Crouch portrays child protagonist Zach with a thoughtful, slightly guarded tone that captures his age and intelligence. He really makes Zach sound wise beyond his years, emphasizing his introspection and quiet strength, especially in the inner monologues where he reflects on past moments with his mother, which makes him even more likable! In contrast, he portrays Bram with a firmer, clipped edge that highlights his arrogance, selfishness, and ego, making him detestable. Crouch gives each of the other men distinct voices that make the audiobook feel almost like a full-cast production—Shane with a competitive, slightly cocky tone, Dave with a blunt, abrasive sound that fits his personality, and Steve, the guide, with a calmer, steadier voice that contrasts the others. The men’s toxic, alpha-male energy comes through clearly, especially with Bram, who sounds very manipulative during dialogue with the other men.
The action scenes are where Crouch’s performance really shines. After the first avalanche hits, he ramps up the pacing and urgency in his tone, making the chaos feel immediate. The rescue attempts and the growing danger on the ski hill are immersive and intense, putting listeners right there with Zach and the others. In the second half, as the stakes rise, Crouch matches the intensity perfectly, making it impossible to put down. The final confrontation scenes are particularly gripping and keep listeners fully invested in Zach’s outcome!
This audiobook is a great fit for listeners who enjoy character-driven survival thrillers, morally corrupt characters, and single-narrator performances that feel like a full-cast production, with a delivery that builds intensity to perfectly match the story!
