Cockroaches and American Existential Pulp

I just read a really interesting and clever book titled "Kockroach" by Tyler Knox. The story is sort of a reversal of Kafka's The Metamorphosis in that the main character is a cockroach turned human. The novel is written in a very dark, noir tone reminiscent of the old Raymond Chandler novels. At the back of the book, Knox includes an interesting article where he describes his own self-defined genre, American Existential Pulp. I found the short essay pretty interesting as he compares great French existential works with the pulp classics of American literature. I also highly recommend the book. It's a little disgusting, but overall very witty and clever.
