ORTHOGONAL BOOK TWO: THE ETERNAL FLAME. San Francisco: Night Shade Books, . Octavo, cloth. First edition. "Relativity and other aspects of physics are dramatically altered in the alternate cosmos of the Orthogonal sequence, comprising THE CLOCKWORK ROCKET (2011), THE ETERNAL FLAME (2012) and THE ARROWS OF TIME (2013), much of the action set on a generation starship. A core concern of almost all his fiction is the philosophical role of science and scientific inquiry in human society and psychology. Along with Ted Chiang, he is perhaps science fiction's most rigorous and challenging author of speculations." - SFE (online). A fine copy in fine dust jacket. (#164040).
