Have you read the Dresden Files by Jim Butcher? It's speculative fiction with a sort of urban fantasy slant--Harry is the only wizard listed in the Chicago phone book. ;)

Also, The Eyre Affair and the other Thursday Next books by Jasper Fforde are great. They're intelligent, literary humor set in an alternate England where people care as much about art and books as people in our world care about sports. I have to love that.

There are more I could recommend, but holy cow I'm tired. I can't wait til the house is ready to list!
