Far in Earth's future, in a post-utopian hell-hole, Hanson works ten solid back-breaking hours a day, shoveling endless mountains of coal, within sight of the iridescent wall that separates what’s left of humanity from their gods. One day, after a tragedy of his own making, Hanson leaves York, not knowing what he will do, or how he will survive in the wilderness without work. He finds himself drawn to the wall, to the elusive promise of God. And when the impossible happens, he steps through, into the city beyond. The impossible was only the beginning.

Gardiner Dozois is widely regarded as one of the most important editors in the history of science-fiction. His editorial work earned more than 40 Hugo Awards, 40 Nebula Awards, and 30 Locus Awards, and he was awarded the Hugo for Best Professional Editor fifteen times between 1988 and his retirement from Asimov's in 2004, having edited the magazine for 20 years! He also served as the editor of The Year's Best Science Fiction anthologies and co-editor of the Warrior anthologies, Songs of the Dying Earth, and many others. As a writer, Dozois twice won the Nebula Award for best short story. Michael Swanwick has received the Nebula, Theodore Sturgeon, World Fantasy and Hugo Awards, and has the pleasant distinction of having been nominated for and lost more of these same awards than any other writer. He has written ten novels, over a hundred and fifty short stories, and countless works of flash fiction.
