Building Harlequin's Moon

A marooned spaceship crew makes a desperate and ruthless decision with far-reaching repercussions in this hard SF saga. Bound for the distant planet Ymir, colony spaceship John Glenn is stranded with engine trouble in the wrong solar system. Over the next 60,000 years, the crew builds a moon, Selene, orbiting the gas giant planet of Harlequin, and populate the moon with their own children. These descendants, the Moon Born, are trained to manufacture the fuel that the John Glenn needs to continue its journey to Ymir. What the Moon Born do not know, however, is that the crew, or Earth Born, have no room on the ship for the Moon Born, and intend to leave them behind on Selene, which is incapable of supporting a permanent colony.
