Initially, I was really excited to read this novel. I love the idea of an isolated research expedition, the potential claustrophobia and dangers that caves bring, and mysterious happenings and the suspense and tension that come with that.  I think somewhere in this novel there is a really interesting story to be told, but for me personally, it was not a good fit.

There were major issues with the pacing. At the halfway point, you get the first inkling that something is off and you think, "Ah, here we go!", but nothing really happens after that to build any sense of tension, not until very near the very end of the book. Even then, when we should be hitting the climax, it falls flat because the characters we have been following are really unlikeable; in fact, they all dislike each other. I couldn't feel anything for them.

On a positive note, the setting is really interesting. And at the very end, when the characters interact with each other and talk with each other as a group, there was a better dynamic than them being in their own thoughts hating each other. The mystery of the cave and the lore of the area also had potential that I wish was explored more.

Thank you very much to NetGalley and the publisher. I received an advance review copy, and I am leaving this review voluntarily.
