Publisher's Summary

A debt of honor: One brave woman ventures alone into a parallel universe to save her old shipmates exiled there decades earlier by a mysterious device called the Transfer Key. She soon learns the alternate universe harbors not just an alien invasion force but a secret that underpins its very existence.

A mission of peace: A long-awaited Klingon-Federation peace conference convenes, led by Ambassador Sarek of Vulcan and Councillor Gorkon of Qo'noS. But both sides have enemies who would prefer the two great powers remain at war - and who will do anything to make certain hate wins the day.

An errand of justice: Captain Kirk and his crew seek the stolen Transfer Key that opens a door between universes, but their hunt is cut short by Ambassador Sarek's plea for help. The Enterprise crew soon become targets in a deadly crossfire - one whose outcome will decide the fate of two universes.

IT IS AS FAR AS IT IS

SHE HAD LET HER MIND WONDER, SO HAD MISSED A TRANSITION
Wow, the characters in the book had the same problem I had. My mind wondered, no matter how hard I tried to concentrate. Book one, was good, maybe they should not have changed authors?
HER SMILE WAS AS COLD AND DEADLY AS FATE.

The series ends here for me.

Large drop off from 1st book in the series

What could David Mack have done to make this a more enjoyable book for you?

Write an engaging story vs just move along a plot line. It truly seemed like he was trying to get from point A to point B in this book and that's what he did . It was journey without any great moments along the way.

Which character – as performed by Robert Petkoff – was your favorite?

Dr McCoy was perfect, his narration is all that saved this one for me

Do you think Best Defense needs a follow-up book? Why or why not?

Great question. When I started this book I had every intention of getting the third to finish the series. By then end of this book I was done and had no interest in wasting a credit to get the third book. I debated the purchase then told myself that I really did not care what happened as I had to work too hard to get to the end of this one. Too bad as I am a big Star Trek fan.

Great continuation of this Star Trek 50th Anniversary Trilogy

David Mack does an excellent job of continuing this story of intrigue, loyalty, and deception. His characterizations are both accurate and yet startling as the conflicts continue to rise and raise in tempo and intensity (specifically the Kirk/Sarek and McCoy/daughter relationships). I'm amazed how two different writers (first Cox and now Mack) seamlessly construct a story that unites a theme and an overall vision for the trilogy. I highly anticipate reading the next one and enjoying the conclusion to this fantastic Star Trek trilogy.

Great sequel

Definitely an edge of your seat action packed adventure. Not as many plot twist as the last book but definitely more action and still felt true to the characters.

Disappointing trilogy

Given the numerous books written about the Star Trek universe and the dearth of unabridged audio versions available to fans, it's surprising that this trilogy was considered worthy to be among the unabridged Star Trek audiobooks offered by Audible. The writing was not anywhere near as well-done as works by many other authors of Star Trek fiction. The dialogue of the main characters felt juvenile and stilted. PLEASE, can't we get more unabridged Star Trek audiobooks?

Maybe a little slow but still good.

Like some of the other reviews this book may have been a little slow moving. Regardless a lot of characters, and an intriguing other universe. Worth hearing if you are a fan.

Trekkie fun again. Better than the first book.

The first book was OK. This middle book in the trilogy was better. Writing is tighter. Action is stronger. The larger mix of characters keeps the tension and interest up, even if the Klingons are (as always) a bit one dimensional.

Again a great narration by Robert Petkoff. He struggles a bit with the female voices, but excels with the iconic Star Trek characters.

Excellent book 2 of a

3 book series. The continuing tale which started in book one. In book two the Enterprise must balance the need to get the transfer key back. And ensure the peace talks between the federation and the Klingon happen.

A story worthy of Trek

Two books in and this story is worthy of Gene Rodenberry's title. I'd say it could make a film Trilogy of a story. Action, politics and exploration abound. Cannot wait until the conclusion in book 3 next week.
