Escape From Eden

Sage has been living within Eden's high walls for several months now, but an unexpected visitor has her scrambling for an escape. She must get back to Colt and the others no matter the risks.
But the outside world has changed, as have the people, and not necessarily for the better. Someone close to Sage has committed the ultimate betrayal, and to stop them, she's going to have to go back to the one place that nearly killed her.
