Query: Grossly Disappointing

Take all the best parts of this book and you end up with a c-grade short story, at best. Character development is 2-stars, sci-fi development is 1-star. Saddest of all, given the fact that Gentry Lee was so intimately involved in the Rama series, he absolutely dropped the ball. This was, without reservation, one of the worst books I have ever encountered.
