Full disclosure: I'm one of those people who think there are way too many vampire books and movies, and that the whole vampire sub-genre has become pretty stale and tired. I know, millions of people love Twilight and its sequels, so I concede it's a me thing.
That all said, despite my jaded preconceptions about vampire novels, I thoroughly enjoyed Peeps. I thought the book's conceit was original and intriguing, and the rest of the story held-together pretty well. Peeps is targeted at young adults but will be enjoyed by adult readers as well. I know, as I'm one of those adult readers who liked it!
