I thoroughly enjoyed this book. The underlying science is solid and well-researched, which is important to me in a sci-fi novel. Preston's pacing is excellent and made it very hard to put the book down.
He offers an action-packed plot which shows us the dangers of allowing religiosity to persist unchallenged, (although his religious characters are a bit one-dimensional). While doing so, he manages to invent a God that even an atheist could believe in, and demonstrates how strong the pull to believe in something can be. Through the magic of suspension of disbelief inherent in reading fiction, I found myself wanting this God to turn out to be real.
If you read Stephen Hawking, Richard Dawkins, and Stephen Wolfram (and I highly recommend you do), you will enjoy this one. If you're looking for intense characterization, romance, and unexpected plot twists, this one is not for you.
This book follows the same kind of story arc as many of the Preston / Child books - in fact the characters are far to similar to the stereotypical roles that appear in others. However, it's an interesting premise and an entertaining book. Preston calls into question what shapes belief and religion....whether you agree or disagree, there is plenty to consider as you read. Recommended for Preston/Child fans.
