It was oookay! There was a lot I liked. The cosmic horror aspect was fantastic. Very spooky, very claustrophobic. 
I didn't really like any of the characters.  They all kind of blended together,  no one really stood out, and i didn't really care about their individual situations. 
The ending was a bit lackluster after all that.  Kinda just dumped a lot of info anti-climatically. 
The writing wasn't great. A lot of short chapters.  You know when in shows they're like "something is going to happen. "And then it goes to commercial and it has to recap the last bit like,  something is going to happen,  and it's this! Now something else is going to happen.... and it goes to commercial again?  It kinda read like that.  It was a bit irritating. 

I'm also not huge on animal body horror, and there was a lot of that. 

Not the worst horror, but I'm not going to be running out to tell everyone they gotta read it.
