Sometimes it's hard to track down a perfect summer vacation book—there's only so much vampire lawyer code-breaking romance that one human can stomach. That's where Charles Stross's Atrocity Archives series comes in: A combination superspy/bureaucrat has been commissioned by a slow-moving but well-intentioned secret organization called The Laundry to protect the earth from math-abusing Nazis and Lovecraftian demons. Stross, who is a prolific and highly intelligent novelist, is clearly having the time of his life on these books; they're witty, thrilling pop-fiction confections. You should read them before the inevitable subpar movie comes along. (University Book Store, 4326 University Way NE, 634-3400, 7 pm, free)
