Demands of Honor is the second of three novels in the Errand of Fury novel series.
The United Federation of Planets and the Klingon Empire stand on the brink of war. Captain James T. Kirk and the Star ship Enterprise are sent back to System 7348 – site of a previous skirmish with the Klingons – for a confrontation with the IKS D'k Tahg under the command of Captain Koloth.
Even as the two powerful ships face each other, trouble is brewing among their crews. On the Enterprise, Lieutenant Leslie Parrish, had a baby with a half-Klingon child and must face a critical decision about her future, while Section Chief Fuller still carries the wounds of the twenty-five-year-old Battle of Donatu V, of which he was one of the few survivors – not to mention his grief over the death of his son, recently killed in battle against the Klingons.
On the D'k Tahg, First Officer Karel finds himself having trap between the scheming, Captain Koloth. While the stakes only seem to be the possession of a single Star System, the ramifications may spread throughout the Klingon Empire, as they find themselves between conquest and honor.
