The Civilization Lost In The Stars

You look through the porthole in your room, as the many galaxies pass with brisk speed. It's been 3 years since the Earth went, as your older brother called it, "Ka-Boom!" Your family was lucky enough to be the last ones on the ship before the Earth exploded. On the small television screen, it said that only the 300 out of 399 ships were able to lift up off the ground, into space, towards the space station that was ready for the last of the human race. All of a sudden, you're thrown off your feet. Alarms start blaring, and a voice came over the intercom, "Everyone Please Stay Calm. Go To The Closest Strap-In Seat. We Have Been Thrown Off Course. Please-" The intercom went out, and then everything went black... {Welcome to space, reader. When you went off course, the stabilizer went out, causing all systems to fail. You're now at the mercy of black holes, other ships, and of course, the more than occasional blackouts. Will you survive, or will you fail your mission to make it back to the fleet, before it's too late?}
