I liked the book. I am told the movie wasn't so great but most of the book was inner dialog which is difficult to in movies. I was impressed by the amount of thought that went into these situations. I was a huge fan of MacGuyver and this was somewhat reminiscent of him. Things might have worked but odds were stacked against everything going right but you care enough about the character that you will it to work. I thought that it was a good combination of technology and math and science. It was a great book from a first-time author.
