Adam and Callie live in a world recovering from devastating plagues that have killed billions. In their rigid society everyone must be ranked as Leet, Mid or Sub. As High Leets, they enjoy all the privileges that this superior rank can offer. But something is terribly wrong.

And what if they are fabricants themselves?
