I've been reading since I was 3 (my first book was "Are You My Mother?" by the late Dr. Seuss), so I've had a lot of reading experience. Some good, some bad, some ok... but here's some of my all-time favorites.

(I guess I have to caution you that I'm a big sci-fi fan - if you haven't already guessed - so consider yourself warned.)

"Ill Wind" by Kevin J. Anderson (an excellent author) and Doug Beason
"The Illustrated Man", "The Martian Chronicles", "R is for Rocket" by Ray Bradbury
"Out Of the Silent Planet", "Perelandra" & "That Hideous Strength" (a trilogy) by C.S. Lewis
"Ender's Game", "Speaker for the Dead", "Xenocide", "Children of the Mind" by Orson Scott Card (a very gifted local author)
"The Songs of Distant Earth", "Imperial Earth", "The Wind From the Sun", "Reach for Tomorrow", "Expedition to Earth" by Arthur C. Clarke

Some X-Files references:
"The Truth Is Out There: The Official Guide to The X-Files" and "Trust No One: The Official Third Season Guide to The X-Files" by Brian Lowry
"The Unofficial Guide to the X-Files" by N.E. Genge
