This is about how a group of people sacrifice everything (including their humanity - they become cyborgs) to try and stop the asteroids in an asteroid field from hitting the Earth. So far, so good. The problem is that it wont hit for 500 years, and it will take several centuries to reach the asteroid field. During the voyage, they lose focus and become increasingly despondent. The story is about how they find new purpose and complete the mission.
This is supposed to be a serious story, but we'll see.
The next one after that is "Quark 2: a Cat and his Boy" which I plan on making incredibly silly :-)
