Daughters of the Terran Revolution

From the Introduction

You've been branded a traitor. With Earth too crowded to accommodate yet another prison, they herded you onto a spaceship and launched you into exile. Meanwhile, beneath the surface of an obscure asteroid, robotic drones were already hard at work preparing your new home.

One crash landing later, things are really fouled up. Thanks to a radiation leak, the handful of you who survived the impact have at most a fortnight left. Your SOS over the ansible was met with dead air. The only survivor will be the AI who was supposed to oversee the colony; your only chance to leave something behind is to tell her your stories.
