I really like Bova and have been a fan for years. This book is just not that good. The story is weaker than the first two books and was disappointing. It could have been great. He tries to use the book to tie up some loose ends from his other books and by doing so takes away from his earlier work. I think the god-like abilities he gives his characters is out of place and doesn't really make sense. Overall I enjoyed the trilogy, but this book left me wishing he had stopped after the second book.
