If you stayed with the series this finale was worth the wait! I say that because the individual books were obviously not well constructed stories in and of themselves. Instead they were simply the “book” of their titles’ part of a continuing story of the series. While a bit annoying at first, once you expected it, that feature of M. R. Forbes story structure did not detract from the joy of the series’ overall story. Specifically to this book, it had an unexpected and very interesting revelation or two that tied up the various threads well and ended this tale most satisfactorily. Highly recommended for sci-fi military and general sci-fi/fantasy fans.
