following the supposed theme I'm reading into in Dan's taste, Try the Nightside series by Simon R. Green. They get a bit formulaic after a couple Novels, but they're still pretty good. There's also the Discworld by Terry Pratchet. Besides the obvious there, There's also Anansi Boys by Neil Gaiman, And basically anything else Neil Gaiman writes.
And just for stuff I liked and Dan might also like, Ready Player One by Ernest Cline, Orconomics: A Satire by J. Zachary Pike, and Psychoshop by Alfred Bester & Roger Zelanzy.
If Dan actually looks through these posts, I hope you find something that interests you. I know these have all interested me in the past
