Galactic Sibyl Sue Blue
Sibyl Sue Blue, better known under its paperback title, Galactic Sibyl Sue Blue, is a science fiction detective novel by Rosel George Brown, originally published in hardcover by Doubleday in 1966. The retitled paperback reprint appeared from Berkley Books in 1968. A German translation, Die Plasmagötter, followed in 1971.
Sibyl Sue Blue, Brown's first novel, is also her first of two novels featuring the title character, "the interstellar adventures of a tough female cop and her teenage daughter". In the initial story, Blue investigates "a foreign virus that caused suicides", leading to a confrontation with "the mass vegetable mind of a menacing planet, an aspirant dictator, and an ex-husband who has become part of the plant life".
