Shadow of Honor - The Droseran Saga, #3

The war he fears may be the very one he's been called to start. Held captive, tortured by monsters of a nightmarish alien race, Marco Dusan clings to a final goal: keep these beasts from the Quadrants, even if it means orchestrating his own death. But his dreams betray that singular design. In them his bonded calls to him across lightyears. Does he leave her to fight Symmachia alone, or risk bringing an unwinnable war to every planet in the Quadrants?  On board the alien dreadnought, Eija Zacdari flounders, torn amidst military machinations, prophecies, and an inexplicable bond with one of the fearsome creatures who have imprisoned her friends.
Only by uncovering the truth about an ancient conflict now shrouded in deception will she find her place. Faced with her true identity, Eija sees her purpose snap into focus, and she realizes the war Marco fears may be the very one he has been called to start.
