Favorites are tough to pick out as it just depends on the mood…
Clive Barker is always a good read (Weaveworld one of my preferences) for fantasy
Rick Moody - most people liked The Ice Storm, I prefered Purple America
Andrew Klavan is good for some light reading, try Dynamite Road or True Crime
Alan Moore is such a good writer of graphic novels that he makes most popular novelists look like hacks.
Brian Greene is probably the best writer of ‘science for the layman’. My wife even liked The Elegant Universe and she doesn’t care for science at all.
I have many others to bring up but I’ll just skip to the end…
Best book I’ve read in the last 3 years is The Club Dumas by Arturo Perez-Reverte. Its a mystery in a similar vein (sort of) as the Davinci Code and it makes it clear that Dan Brown has the writing skill of a fourth grader (I really hated that freakin book, not for the religion but for the sheer stupidity).
Most important book I’ve ever read… Newton’s Pricipia. Probably the most influencial non-religous texts ever written.
Oh yeah, I try to read holy books in my spare time.
