What if souls were a form of currency? What if our potential could be bought and sold? What is the value of a memory?These economic questions and more are explored through twenty-three science fiction and fantasy stories, appearing for the first time in this collection.This anthology also includes economics discussion questions accompanying each of the stories, written by professional economist Elisabeth Perlman, and an afterword/essay exploring the relationship between speculative fiction and economics, written by guest editor Jo Lindsay Walton.
