I liked the first couple chapters, but then it started to feel forced. It didn't help that I looked up Mieville and saw that he categorizes himself as new weird fiction, a la HP Lovecraft. The squid cult then felt like he was checking a box on a list. Then the protagonist (somewhat randomly, I felt) asked his interrogators if they were accusing him of insanity. Checking another box on the Lovecraft list. Meh. 
 Things snowballed from there into a big incongruous mess. Characters felt extreme impact from things that I thought nothing of. They didn't react to things I thought were rather ridiculous. Oy, and the dialogue. I could see what Mieville was going for, but the execution seemed lacking. Either that or this is really just not my thing. 
 If it had only been 300 pages, I might have pushed through, but when I saw that it was 500, I decided to cut bait. I have too many other things I want to read right now.
