Ashes to Ashes

The long-dead Ensign Lindsay Ballard seeks sanctuary aboard Voyager after being killed during an away mission with Ensign Kim three years ago. She is pursued by an alien race known as the Kobali, whose only reproduction method is reanimating cadavers of other species or "resurrection" of the dead through genetic engineering. They had revived her and taken her as a new member of their race.
