As a counterpoint to the favorite book thread, what are the worst books you've ever read?
I have two nominations:
The entire
Survivalist series by Jerry Ahern. I used to read them on the bus over my last few years at school (and first few years at work).
The series starts off well with the main character's journey across the US to find his family after Nuclear war breaks out. However, by the time I'd stopped reading (around No 22), there were mutant biker gangs, cryogenic Nazis, underwater Communists and all sorts of crazy going on. Plus, most of the content was gun porn. Ahern could spend an entire page detailing a custom pistol, and only two sentences describing the actual gunfight.
My second nomination is a book that I can't even remember the title of.

I was stuck in Kabul for 5 days in a tiny transit room with nothing to do. I found a trashy cyperpunk novel about a female assassin who used a pistol with a phallic silencer to 'pleasure' herself before going on a hit. It was terribly written, but all I had to pass the time was eating, sleeping and reading this book until my plane turned up, so I read it 3 times.
