From publisher blurb: There is a war in heaven. Posthumanity has fallen. Something found them out void, and its shadow fell across them. Now they are fell demons of the black, bloody-handed avatars of madness. Humanity cowers behind the Tangle and the meagre protection it provides. But the sickness that dwells within the gods drives them endlessly, and there are many cracks their avatars can slip through. Know them, child, and fear their signs.
