There has been some criticism of this last book. This is because people want what Alex Rider is, big explosions and action sequences. Though this somewhat has this, it has muchamore (muchamore get it.) It has lovable characters, who feel like real people. There's an image in my head on what each scene is, and even though I've finished, I could describe different places in the book. It was amazing, just like all other CHERUB books. It is also REAL! Sure it's not really real, but realistic. There's no bad guy with an eye patch saying "O so your a spy, let me tell you my entire plan to blow up the world, because you'll never get away... Oh no you got away!" It is realistic villains, some who are even kind of cool, and some are despicable. This book is a perfect set of for Shadow Wave (book 12) and I think it's the best of the series. Warning though this is not book for a nine year old to read. It is awesome, but it does have sex, drinking, some light swearing, weed, and violence. Though I think that makes the book better and more real, this may be some no no's for you strict parents. But if you're too young to read it, or get what's happening then wait a few years and go back to it. CAUSE THIS BOOK ROCKS!
