Query: A very good and relevant book

This book raised some disturbing questions about the future of human medical experimentation that don't have simple answers, which I guess was the author's point. Having said that, it's not a dry philosophical treatise. I became involved in the lives of these characters, and as others have said, saw a similarity to A Christmas Carol. It's a whole new take on Dicken's famous story, with a successful experiment playing the role of the Christmas Spirits to teach Professor Marlowe (the Scrooge of the story) a few invaluable life lessons. You'll be disappointed if your idea of a good SciFi novel is non-stop action, since Wakely's book is more deliberately paced and thoughtful. Instead of fast food literature, this is a sit-down kind of meal that- in the end- is not only more satisfying, but more nourishing (and better for you) than anything from a drive-through window. An Audience for Einstein is a very good, intelligent book that deserves to be discussed.
