From the back cover: "It started as a routine patrol for the crew of the Chandley class USS Niwan. For weeks, the vessel had been picking up only normal subspace radio traffic along the route near the Romulan Neutral Zone. Then came the distress signal from within the zone. Help was needed because the senders said they had less than 24 hours remaining in their life-support system. If the Niwen pushed its limits of warp speed, they might make it in time-- maybe."
