Book Description: Four days alone in the desert. Except they’re not as alone as they think.
A year ago, Katie and her cousin Aster survived a night that left their world and easy friendship fractured. Desperate to heal and leave the past behind them, they tackle four days of hiking in the Utah backcountry. But the desert they’ve loved for years has tricks up its sleeve. An illness, an injury, and a freak storm leave them short on confidence and supplies. When they come across a young couple with extra supplies on the trail, they’re grateful and relieved―at first. Riley exudes friendliness, but everything about her boyfriend Finn spells trouble.
That night, after some chilling admissions about Finn from Riley, Katie and Aster wake to hear the couple fighting. Helpless and trapped in the darkness, they witness Riley’s desperate race into the night, with Finn chasing after. In the morning, they find the couple’s camp, but Riley and Finn? Vanished. Katie is sure Riley is in trouble. And with help a two-day hike away, they know they are the only ones who can save her before something terrible happens. The clock is ticking and their supplies are dwindling, but Katie and Aster know they have to find Riley before Finn―or the desert―gets to her first.
Review: Thank you to Sourcebooks Fire for sending me an ARC of this novel!
I truly think that Summer, while not a favorite season of mine, has a book vibe that I really like to adhere to. Much like Fall feeling like the perfect ambiance for a horror story or a cozy fantasy, for me Summer feels like the best time to tap into various kinds of thrillers. One of those sub-genres is survival thrillers, especially if they are set in the wilderness. So I was very excited to read “49 Miles Alone” by Natalie D. Richards, which follows cousins Katie and Aster on a wilderness hike that goes pretty sour and they are suddenly in the web of a killer. This is my FAVORITE kind of wilderness survival tale, and I hopped on in ready for a wild ride!
I’ve mentioned before that I’m not an outdoorsy kinda person outside of the occasional hike through a state or national park, or for some landscape photography excursions. Certainly not multiple days of camping or hardcore hiking and off trail backpacking. But I do love seeing that premise used in a survival/wilderness thriller, and “49 Miles Alone” does a great job of highlighting the real dangers of the wilderness even without having a killer in the vicinity. As Katie and Aster start their journey, it’s already tense due to an incident in the near past that left Aster wracked with guilt and Katie traumatized, and things just keep going wrong and make the tension build all the more. Whether it’s weirdos on the trail, or a storm that manifested out of nowhere and makes the trail that much more unpredictable and dangerous, or Aster suddenly falling ill, many small things keep piling up to turn into one big troublesome and dangerous situation. I’ve known people who do this kind of hiking and camping who have BEEN in these sudden life or death situations where you have to make quick decisions that could end very badly, and watching Katie and Aster have to contend with these things on top of Katie’s trauma and Aster’s guilt made for a lot of really well done suspenseful beats.
But the main point of suspension, when Aster and Katie meet a couple on the trail and Katie suspects the man, Finn, to be dangerous, didn’t hit as hard as i had hoped it would. I normally really like this trope of wilderness savvy people meeting dangerous psychos and having to navigate the wilderness with them, as when it’s done well (like in “The River Wild” or “Desolation”, two films I really like) it can be SO nerve wracking. But I think that in this one it gets a little tripped up, partially due to the timing of meeting Finn and his hiking partner/girlfriend Riley, and partially due to not really getting much insight into the two of them outside of some interactions from Aster’s and Katie’s POVs. To make things worse, by the time we do get to the main driving conflict of potentially being hunted down, it felt a bit more rushed as opposed to the slow build of the earlier parts of the book. I also kind of called one of the big twists pretty quickly, which always kind of pulls the wind out of the sails of a thriller.
So it was a bit of a mixed bag. But that said, “49 Miles Alone” has some really good bits of realistic wilderness survival thrills. It’s a good summer read to be sure!
Rating 7: I loved the tense build up of the perils of an unpredictable hike between tension filled cousins, and I wish it had stayed more in that realm as the dangerous killer on the trail was a little underwhelming.
