First-class entertainment (The Sunday Times) from a classic SF author. En route to an interplanetary research mission, a scientist is abducted by a strange, shadowy race of aliens and taken to a previously uncharted planet, a storehouse of information that would be invaluable--even to an Earth so advanced that time travel allows goblins, dinosaurs, even Shakespeare to coexist.
