Westerfeld, made famous lately by his Uglies/Pretties/Specials trilogy, first caught my eye with this novel. It was the first of his that I read. After reading it, I read So Yesterday, and then started the trilogy. Now I need to read The Last Days, the sequel to Peeps, and the Midnighters trilogy. All of his books are liked by my students.
The PHS book club just finished this one, and some of the students are already interlibrary loaning the sequel. This is not your typical vampire novel.
Cal Thompson has a parasite in him that he contracted through unsafe sex. He craves meat, can see in the dark, can climb buildings and has hypersensitive hearing. He's parasite-positive, or a peep. But he has a different strain. He doesn't go crazy like the peeps he hunts and captures. He is a super-peep and works for the Night Watch, tracking and removing dangerous peeps from New York City.
Cal can't fall in love, well, at least he can't act on it, because then he'd infect his girlfriend. So he fights his urges with a rubber band on his wrist, and still falls in love with Lacey.
The book is interspersed with scientific facts that are fascinating and really add to the novel. I love this book!
