CAN THEY SURVIVE IN A WORLD RUINED BY INTERSTELLAR DUST? An interstellar dust cloud has covered the Earth with particles containing biologically active molecules similar to mRNA. Many humans have died from the dust's effects. Others have mutated into creatures that hunger for flesh, and very few seem immune to the changes. What happens when a lower-caste boy meets a high-caste girl in the middle of a dustfall, and there is an immediate attraction between them? Will they survive? Even prosper? Or will they find that the dust has changed them, too?
