I liked this one, it really felt like characters jumped out fully realized.
The dialogue was perfect although there were times that I felt that Spock spoke a bit too much. When that happened it usually was in the service of some humor. So I found my self forgiving him.
One of the things I love about these books is how little details from the TV show or movies are used and expanded to create interest.
The MacGuffin in the story is a special key that activates an alien machine which has the ability to send a person into another dimension.
The part of the story that stretches plausibility is that this device has been hidden on the Enterprise for a very long time. Two captains ago actually.
The story then travels back in time, to the era of Robert April, the first captain, and the adventure that brought the key to be hidden in the captain's quarters. And, this is the part I liked, it was hidden behind a piece of art that was in the television show.

What I found implausible was that after finding the key Robert April kept a promise not to reveal it's existence to his superiors. Then told the next captain, Christopher Pike, about the key and the reasons not to divulge it's existence to Starfleet Command. Then Pike did the same with Kirk. And none of them turned the key over!
Well, to be fair, they never were put in a situation where the key was a factor. Until now...
But that is my only complaint.
I found the story a bunch of fun and I can't wait to listen to the next installment in the trilogy.
