Obsidio

Kady, Ezra, Hanna, and Nik are trapped on a crowded container ship with thousands of refugees and almost no resources. Their only hope is to return to the planet where their nightmare began, but they have no idea what the occupying forces have done to Kerenza in their absence. On the ground, a resistance fighter and a soldier from the invading army find their past connection tested as the final battle for the system begins.
