Passage at Arms — Glen Cook

The ongoing war between Humanity and the Ulat is a battle of attrition that humanity is unfortunately losing. However, humans have the advantage of trans-hyperdrive technology, which allows their climber fleet, under very narrow and strenuous conditions, to pass through space almost undetectable. Passage at Arms tells the intimate, detailed and harrowing story of a climber crew and its captain during a critical juncture of the war. Cook combines speculative technology with a canny and realistic portrait of men at war and the stresses they face in combat. Passage at Arms is one of the classic novels of military science fiction.
