Attempting a mission to save humanity from destruction from a comet on a collision course with Earth, Dusty finds the mission, his own future, and that of Earth, compromised by his erstwhile fellow astronaut. Really compromised. With his co-pilot having crashed their ship in the comet, preventing them subtly nudging it off onto another route, things are bleak, with only the proxy AI of his religiously motivated ex-colleague to keep him company in his final days. It’s an enjoyable page-turner.
