Cemetery World and Destiny Doll 

Brave explorers encounter a dangerous new world and a terrifying future Earth in these two classic novels by the pioneering SFWA Grand Master.Cemetery World After a disastrous planet-wide war, Earth is nothing more than an elite graveyard—but Fletcher Carson is venturing back in search of a vital bounty. Fletcher, a former artist, is joined by a sentient machine, an ancient, powerful robot, and a treasure-seeking beauty. They soon discover that Earth harbors more than the carefully groomed tombstones. In the wild land beyond the cemetery there are dangerous machines, mutant creatures, and even humans who never left their home planet.Destiny Doll When a team of explorers is beckoned to a strange planet, it closes around them like a Venus flytrap. Assailed by strange perils and even stranger temptations, the small group struggles to survive as, surrounded by creatures of myth and mystery, they are stalked by a deadly nemesis. Even more peculiar is the little wooden painted doll that offers them salvation . . . or damnation.
