I've only read the sneak peek but this book really pulled me in quickly. It's not like anything I've ever read before so I can't give it a comparison to another book. I suppose it's a little like Outbreak or Virus, but this story is much more clever and intriguing since the "Tox" affects each person in a different way. I enjoy the gorey details and even found my face twisted in a look of disgust at one point. The girls' stories have not developed yet but I expect they will and look forward to learning more about them. I also have lots of questions about the virus and the government's efforts to help these girls (or perhaps it's their ulterior motives). This is something very different then the books I usually read. It's fun and gross and I can't wait to read the rest.
