Seriously, you ever try some Vonnegut? Pretty old school, but terrific works. He's the Rowling of his time. Sci if, fantasy, humor, etc. He does it all. I strongly recommend checking into Kurt Vonnegut.
Another author I enjoyed was Chris Moore. His work is incredible. Very funny, with severe undertones. They appear to be aimed at younger audiences, but I know you'll enjoy it. A few to check out;
Coyote Blue
Practical demon keeping
A dirty Job
Many more.
Very awesome stuff. ,most of his works take place in one realm. The main character of one book fits into another's. Sometimes just a different perspective. Hard to explain, really. Just read, you'll see. A Dirty Job was my favorite.
