"Leigh Brackett's well-rounded characterizations and plots are/were a delight."
—Anne McCaffrey

". . . Of all those many science fantasies which have taken their cue from Lowell's Mars . . . Leigh Brackett's is one of the best, blended and spiced like a splendid oriental dish."
—Brian Aldiss

". . . everything about her early stories—their colour, their narrative speed, the brooding forthrightness of their protagonists—made them an ideal and fertile blend of traditional space opera and sword and sorcery. She was a marked influence upon the next generation of writers."
—John Clute, The Encyclopedia of Science Fiction

". . . one of the true godmothers of the New Wave. Anyone who thinks they're pinching one of my ideas is probably pinching one of hers."
—Michael Moorcock
