Shiver by Allie Reynolds: A Snowbound Thriller You Can't Put Down

Five friends. One abandoned ski resort. A snowstorm closing in. And a secret someone will kill to uncover.

Allie Reynolds' debut novel Shiver is a locked-room thriller set in the French Alps, and it delivers everything you want from a winter mystery: isolation, paranoia, old secrets, and a group of people who definitely are not telling each other the truth. If you love Ruth Ware or Lucy Foley, this one is for you.

The Setup

Milla was once a competitive snowboarder, spending a winter in the French Alps training for an elite competition with a tight-knit group of friends. That season ended in tragedy when Saskia, the enigmatic sixth member of their group, vanished the morning of the competition and was never seen again. Now, ten years later, Milla receives an invitation to a reunion at the same remote resort. She drops everything to go.

But when she and the others arrive, something is very wrong. The resort is completely deserted. The cable cars have stopped working. Their phones are missing. And no one actually sent the invitations they each received. Someone has deliberately stranded them on the mountaintop, and a massive snowstorm is rolling in.

What Makes It Work

Reynolds structures the novel with alternating timelines, a brilliant choice. In the present, we are trapped with the group in the increasingly sinister resort, watching trust erode as the situation deteriorates. In the past, we travel back ten years to witness how these friends met, how rivalries formed, and how the competitive world of freestyle snowboarding pushed people to their breaking points.

The flashbacks are where the character work really shines. The relationship between Milla and Saskia is the emotional core of the book, a twisted friendship built on admiration, jealousy, and fierce competition. Saskia is one of those characters who haunts every page she is on, even though she has been missing for a decade by the time the present-day story begins.

The Snowboarding World

One of the most refreshing things about Shiver is its setting. I have never read a thriller set in the world of competitive snowboarding before, and Reynolds, a former competitive snowboarder herself, writes it with authenticity and passion. The descriptions of the mountain, the sport, and the physical danger of extreme conditions are vivid and immersive. You will feel the cold.

It also makes the stakes feel real. These are people who lived on the edge of physical danger for sport, which means the line between an accident and something more sinister is dangerously blurred. The mountain itself becomes a character, indifferent and lethal.

A Few Thoughts on the Ending

No spoilers here, but I will say this: the ending pays off. Reynolds plants clues carefully across both timelines, and the final reveal ties the past and present together in a way that feels earned. Some thrillers fizzle at the finish line. This one does not.

I will also admit that I got genuinely emotional at a couple of points near the end. Reynolds makes you care about these people, even the ones who seem unlikable at first, and that investment is what elevates Shiver above a standard locked-room puzzle.

Who Should Read It

If you love locked-room mysteries, winter thrillers, or stories about complicated friendships, Shiver is a must-read. It is the kind of book you start on a quiet evening and finish at 2 am because you physically cannot stop turning pages. It is compulsively readable, perfectly paced, and genuinely chilling in more ways than one.

Best read with a blanket, a hot drink, and absolutely no plans to go skiing anytime soon.

On a personal note: I don't like how the author goes back and forth in the book. She writes in the present and 10 years in the past and then goes back to the present.
