Mothstorm
by Philip Reeve
A sinister cloud had appeared on the edge of the Solar System, and seemed to be moving closer. Rather than sit idly by, my family and I decided that we should investigate whatever monstrous force of darkness hid within. But how could we have known what mothy horrors lay in wait? Unbelievably, Mother had Met Her Match (which, for a Superior Being of four-and-a-half-thousand-million years old, is quite something), and with the Empire in dire peril, it was up to me to summon all my guile and courage to try to Save It.
