Deep inside a vast debris field in space lies the tiny asteroid of Scrapland — a world once reduced to ruin by a now-extinct race and rebuilt by the robots who now call it home. These robots created a gleaming metropolis and a functioning society of police, bankers, priests, and civil servants, stabilized by the Great Database, which allows any expired robot to be revived. Death became a thing of the past — until outsider D-Tritus arrives amid a string of bizarre murders. Landing a job investigating the killings, D-Tritus finds himself entangled in a web of conspiracy that only his quick wits and a few trusted friends can untangle.
