Russian Roulette, The story of an assasin (372 Pages)

This is the final Alex Rider book in the series by Anthony Horowitz. I've read most of them and really liked most of them. Even while realizing that there is no way a fourteen year old could become an working part of the British MI6, each book is gripping and the reader can't help but "root" for Alex, as he develops his espionage skills. So here comes the last book and it focuses, not on Alex, but on Yassen Gregorovich. a trained assasin and the mortal enemy of Alex. They may be mortal enemies, however, as the reader begins to realize, these two are mirror images of one another. This brings the reader to the question, "When a child experiences dramatic loss of lives in his family, what makes him decide to accept the path of good or evil?" The only thing I'd add to this text is that the reader should first read Stormbreaker, the first book in the Alex Rider series. This is a great example of circular organization, and I wonder if Horowitz had this in mind as he built the series.....hmmm.
