Ash and Dust (The 100)

It's been 97 years since a nuclear war destroyed the earth and rendered it unliveable. Twelve space stations came together to create the ark, a massive space station that holds the surviving human population. There, every crime is punishable by death after you turn 18, to keep population levels consistent.

Bree Burke is a notorious rebel on the ark, having been locked away for her various crimes by the time she was 12, she's three weeks away from her 18th birthday; the day she will be tried for her crimes and sentenced to death.
Bree is young, but she has above average intelligence, and exceptional fighting capabilities, and when these are paired with a strong rebellious streak and an overall stubborn personality, she is notorious for giving the guards a hard time.

But three weeks before her 18th birthday, the one thing that she wasn't prepared for happened.

She was sent to earth.
