Heh... wow. It's been a while since we had one of these threads.
My favorite book was, and still is, The River Why. It's odd, considering I'm somewhat fanatical about science fiction and The River Why is so far from it, but it's absolutely the best thing I've ever read. HUZZAH!
I've also become a great fan of Howard Phillips Lovecraft. For my B-day, my mom special-ordered a copy of The Library of America's Lovecraft collection. It's over 700 pages, and it's thick and black and has a little blue ribbon bookmark thing sticking out of the spine. It's as beautiful in appearance as its contents are horrifying and macabre. ^^
I also enjoy the Discworld series and practically anything that could be considered classic science fiction, and I'm a fan of Douglas Tennapel and Jhonen Vasquez, graphic novelists extraordinaires.
I read too much.
