Armageddon Sky

Commander Worf is sent on a covert mission from Deep Space Nine to investigate a string of raids, only to find himself and the crew of the Defiant stranded on a world sliding toward global catastrophe. Waiting there are Klingons exiled generations ago for their loyalty to Worf's disgraced House of Mogh, whose only hope now rests on the honor of the man who bears that name. The second Day of Honor novel turns a sacred Klingon holiday into a test of what loyalty actually costs.
