[Dark Sun] demonstrates the same ambition; literary skill; unrelenting research; talent for portraiture; understanding of the links between science, war and politics; willingness to stand up to large historical questions; and sound judgment that distinguished Richard Rhodes's 1988 book, The Making of the Atomic Bomb.
