Publisher's Summary

Eighteen years ago the Starship Enterprise thwarted an alien invasion from another universe, and Captain Robert April took possession of the interdimensional transfer device that made it possible. Since then each captain of the Enterprise, from Christopher Pike to James T. Kirk, has guarded this secret with his life.

Now Romulan agents have succeeded in stealing the device and are using it to banish Ambassador Sarek and Councillor Gorkon to an unknown realm in the midst of their groundbreaking Federation-Klingon peace negotiations. With time running out as interstellar war looms in one universe - and alien forces marshal in another - will Captain Kirk and his crew preserve the tenuous peace and reclaim the key between the dimensions?

Weak

Good narrator, interesting story, terrible dialogue. I heard they wrote these books on a very tight deadline. It shows.

Struggled to Finish

As a fan of the original Star Trek TV series it was just okay overall and I struggled to listen to it all the way through. (The first book in the series was really good, the second is the same as the third.) The story is okay, but you have to be fan to really like it. Robert Petkoff's performance is the best part. He has each Star Trek character down and is near spot-on with the accents. I would only recommend this book to Star Trek fans.

Worth a listen

Book three ties up everything nicely. Moves along a little faster than the second. It’s worth a listen if you are a fan. Robert P does a stellar job as always. He helps put you in the setting.

good listen

Very good conclusion to a good story. Haven't read many original Star Trek books but this series is worth a listen.

jumps around too much

it's great, it's original Star trek. But this story has so many sub stories, I just never was immersed; probably also a problem as I listen to it at night before I go to sleep. Really great narration!

Refreshingly Enjoyable

Since I listened to the series out of order, this was the first Star Trek audio book I have listened to and I found it very enjoyable. It was fun to listen to the descriptions of the familiar characters and heard about a new adventure. I look forward to listening to more.

Great Story in Classic Timeljne

I'd love to hear more. Especially by authors like Greg Cox who wrote the first in this series. He very well gets Star Trek.

Narrates like a solid episode

What made the experience of listening to Purgatory's Key the most enjoyable?

Advancing the story line - a little disappointing that it was wrapped up so quickly like an original ST series episode.

The last book in the series was

the best! The journey of the Enterprise is never easy. The third and final chapter is the conclusion of an 18 year secret that previous captain's of the Enterprise knew. Robert Petkoff the narrator performance of all the characters on the Enterprise was excellent. Read all 3 books and enjoy the journey.

The voice acting was fantastic

The voice acting was fantastic! This was one of the best audiobooks I have listened to when it comes to the voice acting. They did a great job making the reader sound like the character that was supposed to be speaking. I really want to find out what happens when they go in front of Starfleet.

sometimes you can read or listen to a Star Trek book and think, "is that it", but not this one, i enjoyed it throughly ....
and you have the rare joy of it being unabridged ....... i wont give away any plot twists, but surfice to say its well worth getting ...... 😎

terrific reader

Robert petkoff's ability to mimic the voices from the original series is spot on. This story is typical Star Trek: great if you're in to it, otherwise a bit cliché. However, it IS pure escapism and the reading is engaging; it's easy to lose oneself for a number of hours without needing to pay close attention.

A wild ride

This the third and final book was just as good. And I still could not see how this would end.
Think I listen to it again 9/10
