What's the worst book you've read?

Truecrime by Jake Arnott has to be THE worst book in fucking existence.

In The Name of Conscience by Nikolai Khokhlov is a close second. It's the only book I stopped reading due to it's massive amounts of fail.

Franz Kafka: "The Metamorphosis"
We had to read it in school, never read such a bullshit before, never after. I can't understand why Kafka is known as such an extraordinary writer. Extraordinary garbage I would say.
