I had this book for Christmas one year as I thought it might be interesting. It certainly started well and at one point it was hard to put down, but Mieville appears to have a weird writing style, inventing words and phrases out of nowhere, and using ' big clever words' to describe a situation or object unnecessarily. This gets old very quickly, and its not exactly a small book!
Basically a squid goes missing from a museum and our hero, Billy Harrow, museum curator, gets drawn into a world of weird god worship, strange rituals, and magic, with a potential end-of-world scenario.
Still sounds interesting and the story is, but the writing style I found awful, heavy and meandering. Not a keeper!
