Hollow Bones is the perfect short read that can easily fill up an afternoon. Great for the spooky season without asking for too much of your time. I really enjoyed the setting of this story, I feel like I rarely ever see swamp horror (though admittedly I wouldn't say I'm well read in the horror genre) and so it really makes the book stand out to me. It makes the story have a distinct atmosphere, coupled with writing that's clearly done its research, and leaves a strong impression.
As a horror, I wouldn't necessarily say I got too scared by things, but I really loved the concept of the monster; I just think the description could have gone all out to describe just how frightening and grotesque it is. I could feel myself just at the precipice of fear so to speak, it just needed a little more push. That being said, the idea of a creature living in the swamp, coming out whenever the swamp dries, is a really neat concept and I can see it making a wider commentary on climate change should it have chosen to.
The thing about Hollow Bones is that I can easily see how strong it could have been if it had been longer; obviously it's a novella so perhaps I'm being unfair with this point but I can easily see, in a full length novel, chapters exploring the history of the creature and uncovering more about it, especially since its mentioned within the story that it was spotted once before. Because it's so short, things happen quite quickly and as others have mentioned here it gets resolved easily. There's not enough space for the characters to leave too much of an impression, but I will admit that the different points of views adds to their charm and makes the world feel alive. There's a lot of space that could have filled up a full length novel to make it a really strong story had there been the opportunity to do so. This is all to say: I can imagine this as a longer novel and would have loved to read if it was! Reading this makes me look forward to whatever the author might write next.
Overall, I definitely think this is worth the read for the unique setting and casual read! As a novella, it worked wonderfully with what is written and makes a great addition for any spooky season readings.
