“At heart a romance of the high frontier, and its most gripping – and moving – parts depict the satisfactions, beauties, complexities, difficulties, and especially the dangers, of working in space . . . . Falling Stars is, even more than the earlier books of the series, a reworking of some of the motifs of Heinlein’s ‘The Man Who Sold the Moon,’ and like its illustrious ancestor, it is about not only vision but heroism and sacrifice. It’s old-fashioned, sentimental, and moving.” —Locus
