Ancient Shores
Something very strange has turned up in Tom Lasker's wheat field: a ten-thousand-year-old sailboat made of an unknown substance.  And then there's the Roundhouse, apparently a doorway to another world, sitting squarely on Sioux reservation land.  How did they get there, and what do they signify  for the people embroiled in their discovery?   This is sci-fi on a grand scale by the author ofThe Engines of God.--This text refers to an out of print or unavailable edition of this title.
