A very good read, but dark, very dark. Although there is an underlying story, it's more a view on a side of life few of us will see, if we are lucky. It's one of those books that is addictive in a very subtle way, every time I put it down I was looking forward to picking it up again.

An excellent read, especially if you are a techie. Enough twists and turns to keep you intrigued without losing you. If sure people will find holes in some of the tech assumptions, but then think of how when star trek started the tech was unthinkable. I could easily see this book being turned into a movie.
