I don't know if I can account for all my books. They're all over the house; we don't have bookshelves. Seriously, you can walk into any room and books are on tables, in drawers, under beds... I do try to keep them off the floor, at least.
I have a huge sci-fi/fantasy collection. I'm looking up at the top of my computer desk and I see:
The Wrinkle in Time quintet by Madeleine L'Engle
The Mysterious Benedict Society, Trenton Lee Stewart
Strunk and White's The Elements of Style, Pearson Longman
Waiting for Godot, Samuel Beckett
The Minority Report, Philip K. Dick
several Trinity Blood volumes, Sunao Yoshida, Kiyo Kyujyo, Thores Shibamoto
various Stephen King books, mostly from The Dark Tower series
the Hitchhiker's Guide series, Douglas Adams (I think they're all up there)
a couple Fullmetal Alchemist volumes, Hiromu Arakawa
The Missing Manual: Photoshop Elements 7, Barbara Brundage
and two coffee table books, one on Skyscrapers and one on American Lighthouses
My husband is the non-fiction reader; he has political interest stuff everywhere. He also likes military history and biographies. I have a lot of true crime and mystery/detective stuff, too. I'm currently reading through my Agatha Christie collection again, in order of publication (I do this every few years). On the side I'm also reading
Watership Down. Haven't read that in ages.
