If I could spell that big word in 'Mary Poppins' I would say that you know the 'Super;istic... whatever.
The book is great, more grown up than Cherub, very informative (Thats a big word) a little bit of humor, I never thought I would say it, but it's better than Cherub, as good as Jason Steed and way better than Alex Rider and Jimmy Coates.
If you imagine the young James Bond books, this is set just after those started but in France. The only bad thing is that like Alex Rider, Young James Bond, Harry Potter, Tom Sawyer, Oliver Twist and all the Cherub characters, these characters are ALSO orphans. Its just Jimmy Coates and Jason Steed who seem to have a parent. I guess it makes them vunrable and us feel sad for them.
So as you can imagine it starts off in an Orphanage run by a big fat guy who eats all the foof, at one point I thought I was reading Oliver Twist again, until it got going.
Overall, a fantatsic book, great story and exciting. I will now read the next two Hendersons Boys books, 6 stars out of 5, lol
