One of my most favorite novels, filled with suspense and keeps you on your toes constantly. It follows the life of young Cadel Piggott, a computer genius who has a mysterious past which even he doesn't know about. His simple life consists of living with his neglectful adopted parents and using his intellect for hacking into high-security networks, soon he is taken to a therapist Thaddeus Roth. This leads to learning about his past and the shocking truth about his past. The character development was incredible, and the protagonist is definitely likable. However, there were a lot of characters to keep track of, some of which weren't even necessary for helping the plot forward. There was plenty of climax near the end of the book but I hated the lack of closure. However, there is a sequel.

Great book, definitely read it

It's insanely good - just sayin. You should read it!!! ~ Gaspar, age 11

I love this book, and I sometimes wish I could be as smart as Cadel.

Good book, good book

The first book in a trilogy. Barely worth reading. =P

Even though most of words in the book I didn't understand, for example the word "binary", the book is still good. Keep me reading day'n' night!!

Wow. Great start to an amazing series. Catherine Jinks hits the jackpot

i can symmpathise jedi. for some unknown reason this book cannot be put down easily. this book reminds me alot of artemis fowl. although i have to admit cadel piggot is nowhere near as engaging as the young artemis fowl.

This books surprised me. I've seen better writing, better developed characters, and better plots, but rarely has a books kept me reading it for six hour stretches, and this book did.
While some of the research behind the book is of dubious quality, and there's something about it that just doesn't quite hang together, this is just such a fun read that you can ignore all that, and enjoy it anyway.
