I was given a copy of this book in exchange for an unbiased review by the author through the MM Romance Group Don't Buy My Love program. My thanks to the author and the organizers of DBML. So this was a little disjointed but the sex was so hot that I moved it from a 3.5 to a 4. Blake and his best friend Ali run a LGBTQ friendly hiking group that specializes in hikes in Yosemite National Park. Blake, and the story is told from his POV, meet Zac who is the only singleton on the tour. Now I know this is a short book, but the movement from Zac, the shy guy, who doesn't meet anyone's eyes, who is seemingly very pensive to the guy who suggests let's play the 1000 questions about sex in a tent was just a little jarring. I kept re-reading passages thinking I missed something. It was very wait, what? Steamy, though!! The entire book is about the hike to various points in the park, and I must say the author has done his/her/ze (sorry, not sure) homework. Lots of detail about the park, about animals, the geology, etc. There are other couples along, some drama and a clearly lead-in into what will probably be another book featuring another character. But back to Blake and Zac - it was almost insta-lust, insta-like, insta-boyfriend but I could sort of feel the connection between the two. My issue was that I wanted more background, more depth. Hard to do in a short book, I realize, but if I had gotten some insight into Blake and why he was all about the casual and Zac, who has broken up with someone but seems to get over this person a little too quickly, I think this would have been a 5 star for me. Now for the smexy - dayuuum - camping and sexin' it up in a tent was hot. Zac and Blake just click sexually and you can feel the sexual chemistry. Now that scene at the slots with Chris - just a little creepy!! Not much goes on, other than the deepening connection between Blake and Zac . With the perilous hiking, I was waiting for something tragic to happen, but nope. Book just sort of meanders along with lots of jizz flying around and then it ends as sort of an HFN for Zac and Blake. This is a new to me author and will check out other reads.
