I was skeptical about reading this book due to all the hype surrounding it but I was not disappointed! Great characters and a fast-moving plot make this one you won't be able to put down.
My only criticisms would be the over-the-top description of the technology, I mean who needs to know what speed the main protagonist's computer is running at or where he downloaded a specific programme? Also, some of the translation is a bit pedantic but you can forgive that as the story moves along at a great pace.
Half way through the second installment now and enjoying that just as much!
