"Having escaped AEtheria, Aral and Rex take refuge on Cthonia near the impact site of AEtheria's power plant. At the same time, a team of armed Cthonian scouts sets out to recover their dead from the destruction.

Upon her arrival, though, Rex recognizes Maire as his mother, who was forced to leave him with a foster father sixteen years before"--Provided by publisher.
