One hundred thousand years in the future, the solar system as we know it is gone. In its place, billions of slowly-failing fragments of a shattered Dyson Sphere haunt the sun, holding the last remnants of humanity and and its daughter races. Gossamyr is an apprentice shaman of a small transhuman tribe on one of the last functioning habitats, until contact with the advanced human society of the Known Nations changes everything she thought she knew about her world. Plunged into a perilous odyssey across the vast cosmic ruins of the Sphere, she is forced to decide the destiny of her people...and perhaps that of all humanity. Enter a world of megastructures and nanotech magic, of superscience and transhuman intelligence, of love and terror and sacrifice, in this epic science fiction adventure!
