I liked this book a lot. As a fan of Facebook, I could understand why Madison was so upset after her profile was hacked. In Madison's case, everyone has a Friendverse, and everyone looks at each other's profiles, meaning everyone saw the nasty things the hacker wrote. Even though I think the characters put a little too much emphasis on this social networking site, but it was still realistic for today's teens. I also liked how the book was a mystery and Madison had to figure out who the hacker was. At several times I thought I knew who the culprit was, but I ended up being wrong, so that was a surprise. But what was really cool about this book was that it had Madison's Friendverse profile page and some other people's pages. It also showed I.M's and texts sent between Madison and her friends. I thought these things were a nice touch and made the book fun to read and look at.
