Warning Signs by Tracy Sierra
My rating: 4 of 5 stars
Tracy Sierra impressed me with her debut novel, Nightwatching, when I read it back in 2024. It was disturbing in such a realistic way, and played off one of my own personal fears, which is being in my house as an intruder breaks in to cause harm.
That horrifying scenario is something I think about a lot actually, I write whilst being home alone for the weekend.

Warning Signs is Sierra’s Sophmore novel and follows 12-year old Zach as he joins his Dad, somewhat reluctantly, on a father-son ski weekend. Before you jump to conclusions and think, how nice, a Dad who wants to spend time with his son, I’ll just let you know, that’s not the case here.
Bram, Zach’s Dad, has his own strong motives for this trip and it has nothing to do with father-son bonding time. Bram’s business is currently in financial distress, and the weekend was planned as a way to woo potential investors.
Bram and Zach are being joined by some rich men, and their sons, in the hopes that Bram will be able to make some deals on the mountain. Because nothing says, let’s spend some money like apres ski drinks.

As you would expect in a Winter Thriller, things begin to go wrong with the group pretty quickly. There’s tensions among the adults and Zach feels like something scary is watching their cabin from the woods.
As the dangers escalate Zach’s unsure who to trust, but he’s sure thankful that he was trained in outdoor survival by his Mom. He might need to utilize all of that valuable knowledge in order to make it off this mountain alive.

While this may have started out feeling like a standard Winter Thriller, a ski weekend gone bad, it took a sharp turn in a direction I wasn’t expecting. Sierra knows how to get a Reader’s pulse racing and I was gripped until the end.
The initial sections of this doesn’t have the same intensity as Nightwatching, which got cooking right from the start, but this story definitely gets there as the story progresses. I wouldn’t necessarily say it’s a slow build, but it does take some time to really get humming.
I wasn’t sure either how I would feel about following the perspective of a 12-year old boy in this type of story, but it really worked. I feel like his perspective was the best way to convey the level of danger and I did grow attached to him. I was on the edge of my seat on his behalf.

At times it felt hopeless, and it definitely made me anxious, but in a good way. I flew through the second half and ended up enjoying the heck out of it. I would recommend this to anyone who loves an intense Winter Thriller, or anyone who had fun with Sierra’s previous book.
Thank you to Pamela Dorman Books for providing me with a copy to read and review. There’s no denying that Tracy Sierra is such a talented writer. I’m really looking forward to whatever she releases next!
