The viewpoint character was Arthur Dent, from the Hitchhiker's Guide to the Galaxy. The plot seemed to revolve around thwarting some plot to destroy the earth by dropping an enormous rock (significantly larger than the moon) on it. Fortunately, the point of the rock was missing, and that was the loophole that made it possible to thwart the plan.
Somehow, my old friend Andrew Urquhart was involved too, near the endgame.
No, I don't claim that it makes sense.
