Schoen was a complete unknown to me, so I do not know if this is his usual style.
As stories go this one does not, to me, have a real plot. The closest to a story line is the search for archeological evidence.
The story feels like a series of disjointed images with an extremely loose connection. there is the search (see above), then an image of a generation ship (crash) landing on a moon, and finally a connection to a great machine, apparently near the center of the galaxy.
I found the conclusion a bit anticlimactic, oh, yes, this seems to be about a species (probably humanity) leaving a planet (probably Earth).
While I do not particularly like the story, I respect the author going where few have gone before, even if this did not work out for me. It must have worked for other people, since it was nominated for the Award.
3/10 from me.
