I recommend American Gods as well. One of Gaiman's better pieces.
The follow up it is Anansi Boys. It's not a sequel, but a story along similar lines as American Gods. Anansi Boys seemed a bit more humorous.
I love Gaimans style. Another author you might like is A. Lee Martinez. His work is more on the lighter side of sci-fi humor. Quirky and very good. I thoroughly enjoyed Monster and Divine Misfortune
Smile if you've got wood.
