London Falling

This started a little slow and procedural for me, but picked up amazingly.
Pro Tip - read the glossary in the back at the beginning if you are not totally familiar with British slang and police terms.

This starts out as a gritty and dark police procedural, but after about 70 pages takes a supernatural turn. The horrors in the book are strange and some how work into your psyche.

I during the last 150 pages I couldn't put the book down.
