Dark Thorn

When an enemy from the past arrives with a request for assistance that only the Herodotus can give. Thorrin and his crew must decide if this once enemy to not only the Federation but to this very universe can be trusted. When the ship goes gravely through the looking glass they find that not all thorns can be removed. For the Empress of the Terran Empire has stolen temporal technology from the Krenim. This Empress is none other than Katherine Janeway. Can the Herodotus restore the proper order of things and save the other side of the mirror before it shatters entirely?
