This is a book that truly transcends age, it manages to both accurately portray life as a kid/teenager whilst also not dumbing down the content because it's classed as YA.
It's a phenomenal start to a series that continues through all 12 books.

This Book (the series actually) make for a nice Change in the world of Children's Books, which are often either Fantasy or Realistic. Whilst this is set in our world as we know it, it is rather improbable that such an Organisation could exist. But it's close enough to reality to remain interesting for Kids who don't enjoy Fantasy so much.
I think Robert Muchamore has done a wonderful Job at creating this world that could be but isn't. Each Story is unique, as is each character. Thank you very much for the treat!
