About This Issue

*Eisner Award Nominee for Best Digital Comic* No man is an island, but Dr. Michael Fisher, a disgraced planetary geologist living on Mars, has never felt more isolated. The situation worsens when both he and Dr. Bex Egunsola, the station's newest biologist, accidentally break through the floor of an unstable lava tube into an ancient subterranean world… and they are not alone.
