Apocalypse law 2

A plague of mysterious origin has swept around the world, killing most of the human population. An ex-Ranger and his thirteen-year-old son are left alone on their farm with no government to rely on. They have taken in refugees, so they may all have a better chance to survive. Together, they farm the land and struggle to feed themselves while guarding against murderous raiders who choose to take from others rather than work for survival. Their farm is in danger and they face starvation without it.
