Query: Very good book--well plotted, well-written.

A captivating read filled with believable characters and fascinating scenarios successfully woven into a great adventure story. The characters are far from one-dimensional and their reactions and attitudes engage the reader in a very thought-provoking manner that continues even after the story ends. And the ending is well worth the read. This is a journey thru space and spirit. Highly recommended. A+++
