This series is really gripping. With every passing page, I tend to compare it with Harry Potter series because of the similarity. Its as if the story is happening in a modern Hogwards with all the state-of-the-art gadgets. The story goes in a fast paced mode most of the time without a single boring chapter. Anyone would be able to finish it off in two-three days. And as the story goes mysteries deepen. I would go with a 3 for this book. Compared to the first book of the series, this one has many cliched scenes and characters and it really tempted me to skim through it. So one star less.
