I also read it based on your recommendation (I think - don't remember clearly) and I really really liked it. The near-future science is overwhelmingly convincing in a good way. What's funny is that I thought the characters were pretty shallow and the constantly peppy attitude of the hero not believable and somewhat grating; usually the quality of characters and their development is a must for me, their shallowness ruins any book. Somehow it didn't happen here. There was just so much of this juicy mind-opening fascinating engaging sciency stuff that kept me at the edge of the chair. I'm really glad I read this book - thanks!
