The 2nd book in the series spares little time getting to the meat of the plot. While book 1 spent a lot of time establishing the factions and environment before getting to much of a plot, book 2 is action packed and doesn't let up until the story is resolved, although it does so with a whimper.
I very much enjoyed a story revolving around the Traveler line, which has been grossly overlooked in Star Trek Fiction. However, giving so much power to one character really deflates the rest of the characters. I greatly prefer the Traveler from the TV series, that was more of a stowaway than some cosmic Superman.
From time to time a character would be a bit off, usually Troi. However, I didn't feel like it impacted the overall feel of the story. I also would have appreciated a bit of a tone down on both Data and Wesley's prowess; they seemed borderline comic book superhero from time to time, and hard to picture in a Star Trek environment.
The overall premise behind the mysterious vessel was a little too simple. Although the idea could, and has passed in several TV episodes, I was hoping for a bit more thought put into it. Also, several of the romances in the book were a little too over the top and at awkward moments.
The overall resolution was nothing more than a few pages of "it all worked out," and didn't really explain much of anything. So, that was a bit disappointing.
I mostly gave the book 3 stars because the writing style was pleasant to read. Reply
