This is a tough one to review, because a lot of people won't like this book. It's a first-person surreal journey from the POV of an unreliable narrator into a section of expanding land that's literally dissolving into madness. I loved it, but folks lacking a tolerance for the weird will probably be put off. For comparison, I would tag it as very similar to Lovecraft's style, both in weirdness and in florid prose, and also to one of my favorite horror books ever, "The House on the Borderland". In a nutshell, if you liked "House on the Borderland", you'll probably like this. It also reminded me quite a bit in tone and narration of the early 70's horror film "Messiah of Evil", an underrated gem. 
 What you don't get: A concise plot, vivid characters, snappy dialog, or the usual :Answers in the climax" structure. 
 What you do get: A totally immersive journey into crazyland in the shoes of an emotionally isolated woman whose own personality traits both make her the perfect fit to the environment and also dangerously vulnerable to it, from a sanity perspective. 
 I loved it. Depending on your tastes in fiction, your mileage may very definitely vary.
