I actually found this book on another library's book blog, and it was quite different than I expected. It's a very quick read, as the chapters are very short and the story moves along at a rapid pace. It's a bit darker and more intense than I anticipated; it is not a children's/young teen book at all. It also isn't as predictable as many YA books , so it was fun to be surprised by the plot developments. The ending will certainly leave you hanging, so make sure you have the next book, I am the Mission, ready and waiting!
(Note: I am the Weapon is the first book in the Unknown Assassin series. It was first published as Boy Nobody, but later republished as I am the Weapon once the book turned into a series.)
