God's Demon by Wayne Barlowe - Truly, this novel presents the most interesting version of Hell I've ever seen. I'm sorry literature buffs, but he kicks the crap out of Dante, who I have also read (that is to say, The Divine Comedy was still pretty good). Barlowe does a great job of creating a compelling fantasy world out of the image of Hell, and scores (ok, maybe not THAT many) compelling characters to inhabit it. Now that's saying nothing about the plot (which I awesome, by the way). It's supposed to be the first of a series, and since he hasn't yet released the second one I interpret this to mean that you people need to go out and buy it. Please, give this man the proper motivation!
Thud! by Terry Pratchett - This is the first and only Discworld novel I have read, and if this one could be called "average" amongst his works then I would like to know where his Pulitzer Prize is. I'm almost certain those art snobs would never give that award to an interesting book. Yeah, it's full of good ol' British humor, an eclectic and expansive cast of characters, and some symbolism and social satire that's witty and not to hard to decipher.
Wolf of Shadows by Whitley Strieber - Your mileage may vary on this one, folks. I liked it, but then again I really like wolves, so that may have been a big part of it. It's one of those Cold War anti-nuclear books, and it takes place right after a nuclear holocaust where a mother and daughter befriend (or at least follow around) a pack of wolves, told from the perspective of the wolf pack leader, the titular "Wolf of Shadows." It's a pretty light read, too. I finished it in two days.
Of course, you're looking for suggestions, right? Well, I'd like to throw in just about anything by H.P. Lovecraft, Ender's Game by Orson Scott Card, Fahrenheit 451 by Ray Bradbury, Dracula by Bram Stoker, and The Moon is a Harsh Mistress by Robert A. Heinlein. I've also just started reading The Golden Compass, first of the His Dark Materials trilogy by Philip Pullman. While I'm just nearly halfway through with it, I like what I've seen so far, and I hear that somewhere along the line they kill God. Good stuff.
