Let me begin by saying this is a weird book. I generally enjoy wired book because books are supposed to take you into an alternate reality right?
This book however makes Kafka look tame by comparison. The premise is that A man in hired to go undercover to see if a prison guard is really a Nazi Camp guard in hiding. It delves into the world of drug addicts and prostitution and other underbelly activities. It takes twist and turns that no reader could have anticipated. It has dark undertones throughout the book. It also has a good psychological bent as it explores the dark side of human nature. It was entertaining to be able to see that whole spectrum without actually being in any harm. He also injects humor into his subject so you don't feel as if he is dragging you down. Some books after you have read them leave you feeling more depressed than you were before reading them. Not so with Pain Killers.
When I arrived at the end of the book I was like what?! huh? That is a good thing in my opinion. Not many books have that ability. A book that takes you on a ride has accomplished its purpose.
