   Summary

   Ryland Grace is just starting to get used to his new life on Erid, and he does not miss Earth, or humanity whatsoever. At least, that's what he tells himself. Until Eridian scientists discover a signal, a message, coming from a strange moon around a dead star.
   Ryland Grace does not want to go back to space, but there is something about this signal that seems so important, that both intrigues and frightens him. It's just a scouting mission, and he'll have Rocky there the whole time if something goes wrong.
   What's the worst that could happen?
