Sam J. Lundwall was a Swedish fan, critic, and writer. ACE editor Donald Wollheim explains in his introduction to these stories that after contracting for one book, Lundwall got the idea of treating the situation in two very different ways - and the Ace Double format is the perfect medium to present such different "takes." The situation of these stories in common is planet fall on a long-abandoned world.
