Star Trek Voyageur, tome 5

Hope flares for Captain Kathryn Janeway and the crew of the USS Voyager when their sensors detect a signal that could lead them to a way home. But as the starship Voyager races to the source of the signal, the crew find themselves in the middle of a raging battle between two warring races, a battle that has lasted for hundreds, if not thousands, of years. Now, to find a way home, Captain Janeway and her crew must make their way through the most violent space-born conflict ever known—with both sides determined to destroy them!
