To make clear why past winners deserve recognition as pro-freedom sf/fantasy and how they fit the Prometheus Award, Appreciations of past winners have been written and posted. Here’s the Appreciation for Ken MacLeod’s Learning the World, the 2006 Prometheus Best Novel winner:
MacLeod’s inventive first-contact novel explores the politics and uncertainties involved from two perspectives: the natives of the planet and the “alien” (human) visitors.
In some ways modeled on classic Heinlein juveniles and a departure from his other future-Earth-solar-system novels exploring the implications of libertarian and Marxist ideas, Learning the World offers as a primary viewpoint character a teen girl living on an interstellar colony ship about to enter a new solar system.
