When I have the time, in general you'd find me between sci-fi, psychological thrillers, and American Civil War period. At the moment, as I look at my bookshelf, you would probably find me somewhere between a Thomas Harris novel , a Robert Heinlein novel (I have about 30+ of his), or one of the novels by Michael and Jeff Shaara, with Douglas Adams, Tom Clancy, William Gibson, H.P. Lovecraft, (and as soon as I actually have more time to catch back up) Neal Stevenson, and J.R.R. Tolkien thrown in for spice.
(I also have a copy of both "The Art of War" and "The Bhagavad Gita" packed away somewhere I need to dig out and finish as well.)
(Yes, I have a weakness for bookstores and good books, but don't let them know that...)
