FMS NIGHTINGALE Anthology 4

The fourth collected anthology of the FMS Nightingale saga brings together Books 16-20 of the continuing science-fiction medical adventure series.
Captain Elsa Mantis and the crew of the Federation Medical Starship Nightingale return for five more missions where medicine, time, memory, and morality collide.
A stranger appears on the ship's hull with no suit, no vessel, and memories of a thousand timelines. An ancient galaxy has been turned to salt by a law older than civilization itself. A pyramid in ancient Egypt reveals itself not as a tomb, but as a dormant hospital designed to rewrite humanity. A dying star becomes a weapon against the world it once warmed. And a nineteenth-century steam train drifts through deep space, trapped in a collapsing time loop with history itself riding aboard.
Across these five missions, the Nightingale faces impossible patients, cosmic mysteries, and ethical choices with no easy answers. The ship is not a warship. It is a hospital, a refuge, and a promise: go where others cannot, help those who are suffering, and keep moving forward when every rescue has a cost.
