Ghost of a Chance

Badly damaged after a brush with a dwarf star, Voyager finds a world tearing itself apart from volcanic stress below, and a second ship, the Televek, offering help that doesn't sit right with Janeway. Prime Directive concerns collide with the urge to save a doomed population, and a string of spectral warnings turns out to be pointing at a real threat the crew can't afford to dismiss as ghosts.
