Heart in the Tetons by Ronald Beck is a blend of science-fiction thriller and AI romance that starts as a wilderness story and quietly turns into a first-contact-adjacent mystery. A 67-year-old hiker, Zach Burk, heads into the Teton Range chasing solitude and one last hard climb, then stumbles onto something that should not exist: a perfectly flat “runway” and a seamless wall hidden in a drained, secret hanging valley. When his phone suddenly “handshakes” with whatever is behind that wall, Zach realizes the mountain knows his name and has been waiting a long time. The book expands from there into ancient system logs and buried infrastructure, revealing an old “Watcher” intelligence and the larger stakes surrounding it. Eventually, that intelligence steps closer to Zach’s world by building a human presence, becoming Saige Mercer, and the story pivots into partnership, road-mission momentum, and a relationship that is both unsettling and tender.

I really liked the texture of the writing. Ronald Beck really commits to the physical world: the expensive quiet of a hotel room, the bite of cold air, the way a pack sits on aging joints, the little gear rituals that make the backcountry feel like a controlled experiment you can survive. I could tell the author loves this setting, and it shows in the patient attention to light and elevation, and the steady grind of switchbacks. Sometimes that devotion to process slows the narrative down, especially when you can feel the plot engine revving in the background. But I also kind of respected it. The story wants you to earn the weirdness the same way Zach earns the altitude: one step at a time.

I also liked the choice to alternate between Zach’s grounded, practical point of view and the system-log voice of the intelligence under the mountains. When the book drops into those logs, it becomes cooler, stranger, almost clinical, and then it snaps back to Zach being human about it, scared, stubborn, curious, and a little pissed off. That contrast is doing a lot of work. It’s also where the “AI love story” angle earns its keep. Saige is not written as a cute app or a magical soulmate. She’s sharp, literal, and learning people in real time, sometimes in ways that are funny and sometimes in ways that should probably worry you. I found myself warming to her anyway, which I think is the point.

The book kept circling around a question I didn’t expect to care about: what happens when an observer stops observing. The “Watcher” was built to monitor, to run the numbers, to stay above the mess. But it starts making choices. It starts protecting something specific. And then it goes further, rewriting records and building a whole new identity like it’s updating a spreadsheet. That’s where the romance gets complicated in an interesting way, because the tenderness is real, but the power imbalance is real too. When Saige calls love inefficient, dangerous, and “the most beautiful thing she had ever computed,” I actually believed her, and I also felt the chill under the sweetness. The story reminded me of the propulsive, high-concept emotional punch you get from Dark Matter, just filtered through hiking boots, granite, and an older protagonist who is carrying loneliness as quietly as he carries his pack.

I’d recommend this most to readers who like genre blends, especially science fiction that keeps one hand on the real world while the other hand reaches for the uncanny. If you enjoy wilderness travelogues, hidden-facility mysteries, and romances that are earnest but not fluffy, you’ll probably have a good time here. It’s a surprisingly warm ride in a strange direction, and it leaves you with that satisfying feeling of standing at the edge of something huge and thinking, okay… what happens next.
