My reading habits, in roughly the order I like them:

FANTASY!  From Harry Potter to DragonLance, I like them.  Not into "gothic" stuff (like Ravenloft), though.  Fravorite authors: Robert Salvatore, Elaine Cunningham
Adventure--favorite author: Clive Cussler
Mystery--mostly murder-mysteries.  Favorite authors: Lilian Jackson Braun (The Cat Who... books), Sue Grafton ("alphabet" mysteries)
Sci-Fi--mostly Star Trek
History--currently reading the history of VMF-214, better known as Pappy Boyington's Black Sheep
True crime--Ann Rule

That's about it.
