Mother Lode

Plot

After a five-year mission to the edge of the known universe, Erin returns home to find that she has inherited a Mule class mining tug and a set of coordinates that might open the way to vast wealth--or disprove her late father's foolish dream. And when Erin sets out to search for the "big strike", she cannot anticipate that at her journey's end waits a mystery far older than the human race itself.
