Query: An entertaining but not overly deep novel.

As is usually the case with Peter David, the writing style is excellent; as usual, he manages to tell an exciting action-based story without losing his sense of humor, which is rare. As an added bonus, this story has its beginning in the time of Captain Pike, just after the events in "The Menagerie"; after a chapter or two, we move forward to a standard original-series story, set at some point after the fourth movie. ("The Voyage Home")But while the story is exciting, a good read, with action, pacing, and characterization that is all one could ask for, it is, ultimately, a lightweight novel. Which is not necessarily a bad thing; that's going to be true of most stories in any protracted series. They can't ALL be world-beaters; this one is a good light-reading episode with just a hint of the deeper thought-provoking concepts that make some Star Trek stories great. Not enough to be great itself, but just enough to be very good.
