This book gave this two part series a fitting end. 2000 was a good year for Voyager and Deep Space Nine in the books so why not put them all together in a action packed adventure taking place in an Alternate Universe? Seven of Nine does a wonderful job this time when she teams up with Trek's leading ladies; Kathryn Janeway, B'Elanna Torres, and Beverly Crusher. For you New Frontier fans, you'll enjoy the Mirror Cameos of Dr. Selar and Robin Lefler. This was action packed and one heck of a ride. Deanna Troi and Kira face off finally and who wins and how is quite enjoyable. Everyone in the novel falls into place with every thing explained. The author did a wonderful job of pulling in all of our favorite characters from the three modern day Trek series plus NF. You see Lwaxana's Mirror Counterpart, Ro Laran, Koloth, Tom Paris, Harry Kim, Chakotay and many others that'll make you smile and laugh when you see them all in one place, interacting. If they wanted a sure hit and tip off to the Trek movies, this would have made a rather fitting movie with all the series' contributing their best characters. Every Trek fan needs to read these books. They are some of the best books of 2000 for Trek in my opinion, hitting it high with DS9's Millenium series, the New Frontier come back and Voyager's Dark Matters. Start your new year off right by reading a book that places all the favorite and admired Trek females in one universe and with each wanting to achieve one goal. Not everyone will survive and you know it, but you still will get a kick out of reading about Agent Seven of Nine's most dangerous and eye opening mission yet.
