Dick, Philip K.
A new teleportation technology makes travel by spaceship redundant. A new colony, Whale's Mouth, is the destination for forty million colonists, but it is a one way trip - no teleportation back to Earth is possible. The only way to return is by spaceship, an eighteen-year journey. Rachmael ben Applebaum, whose spaceship business has been ruined by teleportation, decides to make the journey to Whale's Mouth in his own ship, Omphalos. Driven by visions that the utopian vision may be false, he chooses to make the trip in case a colonist may decide to return. Powerful figures oppose his journey.
