Season Two Main Cast

"Would you sacrifice freedom for survival?"

I've survived a war with the Grounders and near death, only to find myself stuck inside a fortress with no way of escape. Out of the 100 of us delinquents sent to Earth, 48 of us remain. Sure, Mount Weather was our intended destination, but everything about this place seems a little to good to be true. I shouldn't be complaining, after all, their medical staff saved my life and the lives of my sister and friends. However, five of my friends and the man I love, are still out there somewhere. As I soon fear this place isn't all it's cracked up to be, I find myself at a fork in the road; leave with my sister and find help or stay with my people and protect them until help arrives. Either way you look at it, I have to step up once again. Only this time, I can't be afraid of the decisions I have to make. I have to be stronger and harder. I just may have to embrace the darkness that comes with being the Princess Commander.
