The Keseburg once boasted a complement of fifty thousand. Generations of hardship, space hazards and disease have whittled it down to just under thirty thousand. That was the number when a small crew of resource miners departed on a routine asteroid run three months ago. But when they return home to the ship, all traces of their friends and family are gone. The Keseburg is silent, adrift, and running out of fuel. As they search the massive ship for survivors and answers, something else stalks them. Something that does not belong on the Keseburg.
