I got a used first edition of Arkham House's Shadows Over Innsmouth, which is a compilation of Lovecraft-inspired stories featuring the Deep Ones. It's hit-or-miss, which is to be expected from a Lovecraft-inspired comp. I was happy to see one of the better stories is exactly the kind of pulp detective/cosmic horror mash-up that I'd convinced myself must exist *somewhere.* The last story, which I haven't gotten to yet, is by Neil Gaiman, which always is a good thing.
At the same time I got a cheap copy of Mason & Dixon, which despite being my favorite Pynchon novel is one of the only ones I didn't own. The younger clerk seemed surprised I was attempting to read it while the older one sighed, "I don't go to parties anymore so I won't have to talk about Gravity's Rainbow."
Current summer (re-) reading is Foucault's Pendulum, under the woefully misguided assumption that if Dan Brown's awful conspiracy-theory books are good beach reads, then an eggheaded postmodern take on the same must be that much better.
