An out of practice reader discussing the books I get around to reading.
Overall, I really loved this book. 100% would read it again. The atmosphere was awesome and I really enjoyed the character developments in Gyre and Em, as well as their development in relation to each other. The pacing felt awesome as well. There were enough highs and lows where I didn't feel like the book was rushing along or dragging. It could be slow at times but never in a way that made me reluctant to pick it up again.
As far as things I would have liked, I feel like there were some missed opportunities in regards to the horror element of the book. I really would have enjoyed more in regards to the technical nature of caving. When I pictured it in my head, it felt more like walking through a mine/rock climbing than caving itself, which kind of lessened the effectiveness for me. Having worked with and been friends with cavers, I know about maneuvers and risks that literally happen as part of typical caving that would have amped the horror up in this book to a whole new level. Seriously, look up Jam Crack in the Glenwood Caverns and that alone demonstrates what I mean.
Final rating 5/5: I truly enjoyed this book and highly recommend it.
Final thought: It'd be cool to have this adapted as a video game. That's kind of how it played out in my head and I think it'd be a lot of fun to play a game as Gyre.
