“I just didn’t know what to do with my stuff until I stumbled into science fiction and fantasy,” Le Guin says. “And then, of course, they knew what to do with it.” “They” were the editors, fans, and fellow-authors who gave her an audience for her work. If science fiction was down-market, it was at least a market. More than that, genre supplied a ready-made set of tools, including spaceships, planets, and aliens, plus a realm—the future—that set no limits on the imagination. She found that science fiction suited what she called, in a letter to her mother, her “peculiar” talent, and she felt a lightheartedness in her writing that had to do with letting go of ambitions and constraints. In the fall of 1966, when she was thirty-seven, Le Guin began “A Wizard of Earthsea.” In the next few years—which also saw her march against the Vietnam War and dance in a conga line with Allen Ginsberg, when he came to Portland to read Vedas for peace—she produced her great early work, including, in quick succession, “The Left Hand of Darkness,” “The Lathe of Heaven,” “The Farthest Shore,” and “The Dispossessed,” her ambitious novel of anarchist utopia.
