I am a freshman in high-school and my mom recommended me read this book for an assignment. (I am no reader at all). As soon as I read the first 10 pages I was hooked. Read the whole thing in 3 days and loved it. Wasn't a cringe story and had you on your toes the whole time. It was filled with action and excitement. This has to be the one book u read that was intriguing on every page it had. After that I had read the rest of the series and was even more baffled and amazed at how consistent this series was every book of it was great. Which is really hard to find to the point that I can't really rank any of them because they all were so good. Strongly recommend this book for all ages over 11 because it is a little long but I didn't mind it being 420 pages because I was having fun reading it. Which is really hard for me to say about a book. The whole series was great I don't think there will be a more consistent and great series than this.
