When your entire family is caught up in a world war with flesh-eating fog and robotic monstrosities, the only question that matters is: what are you willing to do to survive?

Siblings Kris, Albany, and Millie each inhabit a different part of the war – special ops and cannon-fodder at the front and codeworks behind the line – which transforms and transmutes how they think of themselves and their allegiances. They dump everything they know – confessions and consolations alongside poems for fallen friends and battleground sketches – into letters.
