The Author clearly has no idea what he's writing about. His knowledge of computers, cryptology and programming probably came from his 14 year old nephew.
He also really seems to hate Spain. He must have had a bad experience there.
The characters are laughably dumb and disgusting despite being the best and brightest minds in their fields. And when I say disgusting, I mean it. Fat, sweaty, over sexualized, repulsive characters. Not a redeemable character in the entire book.
In short, unless you want a good laugh at a really bad book... Do not read this book.
