I bought only 20 books today (last year I bought twice that on opening day). There are fewer options this year, and very few boxes of books stuffed under the tables. We only spotted a couple of book sharks, and people were only rude and tense in the sci-fi/fantasy section. (There tend to be a lot more blank, menacing stares and blatant poaching in that section on any day.)
Anyhow, I am happy with my smaller haul. My best find of the day: Whose Body? by Dorothy L. Sayers. Mystery lovers will know this as the first of her Lord Peter Wimsey books, but when I first saw it I thought it might be a hysterically inappropriate children's story.
I also found The Fairy Tales of Oscar Wilde, a literary analysis of the Narnia books, The More Than Complete Hitchhiker's Guide (for $1!), and an L.M. Montgomery book I've never seen before which doesn't even appear to be about a wistful orphan. Score!
