From the front flap of the Gregg Press edition: "Two Worlds brings together in one volume two unrelated short novels, Question and Answer and World Without Stars. Question and Answer involves a serious movement by the scientific establishment to stop space exploration on the grounds that man is not good enough to go out in space. It is a novel that invites us to take a long, hard look a issues of political, social, and moral import. World Without Stars, which the author considers one of his best novels, is set on a distant planet in the far-future. A spaceship has been shipwrecked, and it crew is determined to find their way home. The planet and the aliens who inhabit it are drawn in glorious detail, but it is the human relationships (including a love affair that has lasted 3000 years) that have endeared this novel to discriminating readers of science fiction since its publication. ... This first hardcover edition includes the complete lyrics to "Mary O'Meara," a love ballad sung by the hero of World Without Stars, and a new introduction by the author."
