Shadow is just that. The Shadow where a good story could have gone, thrown by a publishing idea that doesn't understand its subject.
The story follows the crew of the USS Voyager, stuck thousands of light-years from home. Diverting from their journey to observe the majesty of a stellar collision, where they discover another ship -- the remnants of the civilization of this star system. They are running away, but will be unable to get to safety before the explosion of the stellar collision destroys them. All this, while a member of the crew, Seven of Nine, narrowly avoids death with alarming frequency.
The pace and literal ticking clock of the novel set a pace that, even short at 272 pages reads more like a script for an episode. A civilization faced with its own extinction gives fertile ground to how you face failure with hope. And a mother looking after her child among the chaos of a disaster also setup not just hope, but determination.
Unfortunately everything is either off-tone or unused. The first problem is that Star Trek: Voyager is the sunniest, most hopeful version of Star Trek. The idea of Section 31, birthed by the darkest Trek sheep, Deep Space Nine, flies directly in the face of it's hopefulness, to the point that the captain, upon learning of it, does nothing. The pacing while fast like an episode, leads to glossing over important details or ideas. Millions of people simply abandon old-held ideas, a civilization deals with upheaval as if it's just another monday.
The familiar characters are not quite right, Tom Paris, is just a little too argumentative. Tuvok is just a little too-rigid, the Seven/Torres dynamic is heightened just a bit too far. Chakotay is the only spot on... largely ignored, just like the show. The alien's ship is segregated, setting up the classic Trek homily of eliminating class/racial distinctions, is ignored. Instead this Section 31 angle is shoe-horned in to the story as the complication, almost as if the main story was conceived separately.
Perhaps the fact that there are two authors are to blame. But the story is short, forgettable, and not worth the time unless you are a completionist.
