I make it no secret how much I love the Haven’s Rock series, and I’ve been with this crew since they were first introduced in Rockton. As the fourth installment in this spinoff series, First Sign of Danger delivers the same tense, wilderness-set mystery I’ve come to expect, nothing more, nothing less. But while that may sound like business as usual rather than anything standout, it’s still a satisfying read.

The story picks up six months after the previous volume, Cold as Hell. Casey Duncan and Eric Dalton are new parents! Their home, the off-the-grid settlement of Haven’s Rock hidden in the wilds of the Yukon, continues to serve as a sanctuary for people looking to disappear, and this is where they are content to raise their family. Even the nearby mining operation has, for the moment, fallen into a workable truce. Boundaries are being respected, and both sides are keeping to themselves, at least for now. Everything feels relatively calm and balanced, just the way the town’s residents would prefer as they head into winter hoping for as little drama as possible.

But that fragile peace is abruptly shattered when Casey and Eric encounter two hikers who have wandered far too close to Haven’s Rock’s borders, raising immediate concerns about exposure. Thinking quickly, they point the interlopers away from town, towards a safer direction. But when they return the next day to make sure the hikers have moved on, they instead find one of them dead and the other missing without a trace. With no clear idea who these people were or why they were in the area, Haven’s Rock goes on high alert as Casey and Eric begin digging into the mystery. At best, the hikers’ presence is an unfortunate coincidence, but at worst, it could mean a new threat has found its way to their doorstep. Given everything this town has already endured, there’s too much at stake to take any chances.

One of the things this series does well is atmosphere, and that still holds true. The setting once more plays a starring role, the Yukon providing an active source of tension. Between the isolation, the harsh conditions, and the ever-present danger of nature and wildlife (speaking of which, there is a truly harrowing scene involving a bear in First Sign of Danger), there’s just this constant awareness in the back of your mind that things could go wrong at any moment. It gives the story a survivalist edge that perfectly complements the police procedural elements.

In terms of character development, Casey and Eric are now navigating a completely new phase of their lives with their six-month-old daughter, Rory. There’s a clear adjustment period as they figure out how to balance parenthood with their law enforcement responsibilities, but the book takes a refreshing approach here. Instead of playing up the usual themes of stress, exhaustion, and guilt in stories about new parents, it highlights how a strong support system can make all the difference, even in a remote place like Haven’s Rock. Here, the side characters step up. While overall they are in more background roles this time, their presence is still felt in meaningful ways, reinforcing the town’s sense of community. Sure, Casey is tired, but she’s never forced to choose between her job and her child. Rory, meanwhile, is growing up loved and cared for by a network of honorary aunties and uncles pitching in when needed, giving mom and dad the space to do what they need to do.

The mystery itself is engaging, though inevitably it feels familiar at times. Some of the plot points are recycled, easy to anticipate because we’ve seen them before. That said, I come at this as someone who genuinely loves this series, and there’s an undeniable comfort of returning to something I know. At the same time, I’m realistic. Between this series and the original Rockton run, we’re pushing close to a dozen novels in this world, and it’s starting to feel like we’re nearing the natural end of the road. And maybe that’s why I’m not all that upset about the author’s news that the next book will be the last. As much fun as I’ve had, quitting while you’re ahead is never a bad thing, and in this case, I’d much rather see the series wrap up on a strong note than stretch things out unnecessarily.

At the end of the day, First Sign of Danger is another dependable and easy-to-enjoy installment of the Haven’s Rock sequence. I also had the pleasure of listening to this in audio, and narrator Therese Plummer as ever does a fantastic job as Casey, bringing a natural and down-to-earth tone to her voice that fits the character completely. While this book doesn’t quite reach standout status for me, it still delivers a satisfying mix of mystery, character development, and wilderness tension, which are the exact ingredients that have always made this series so enjoyable.
