Centuries ago, one small town in Germany disappeared and was never resettled. Tom, a historian, and his theoretical physicist girlfriend Sharon, become interested. By all logic, the town should have survived. What's so special about Eifelheim? Father Dietrich is the village priest of Eifelheim, in the year 1348, when the Black Death is gathering strength. To his astonishment, Dietrich makes first contact between humanity and an alien race from a distant star, when their ship crashes in the nearby forest. Flynn gives us the full richness and strangeness of medieval life, as well as some terrific aliens.
