What this book is about
Scott Westerfeld's YA sci-fi/horror follows Cal, a nineteen-year-old from Texas who came to New York, hooked up with a woman, and discovered she gave him a parasite — one that usually turns its hosts into the cannibalistic, light-fearing creatures called peeps. Cal is one of the rare carriers who gets enhanced senses without the madness. Now he hunts the infected while tracking down everyone he may have exposed. Each chapter alternates with real parasitology facts that are genuinely fascinating and disturbing. The sexually transmitted nature of the parasite is integral to the story.
