Radioactive. The 100 Fanfic.

A nuclear war destroyed earth about a 100 years ago. The rest of the human race were sent into space in different space stations. As the years went by the stations decided to come together and call themselves the ark. Due to the limited resources people could only have one child and were given small portions of rations. Even the petty crimes were sentenced to death unless you were under eighteen. Then you'd be locked in a solitary cell. The plan was to wait a 100 years until going back to earth to check if it was survivable. However, the ark was quickly running out of air causing them to send 100 children prisoners to the ground.
