Description: Ra is a 21st century prison camp that also acts as facility for harvesting metals—from the Sun. The prisoners have all been banished here for extreme crimes, but none of them remembers anything from their past. As a lethal disease slowly spreads through the camp and the prisoners are abandoned, Ian Hutchings must find a way out if he and his people are to survive. But dark secrets lurk, and as they try to survive both the illness and the inferno they live on, they will discover a truth even stranger than their own circumstances.
