 Based on an outline and notes created by Heinlein in 1955, Spider Robinson has written the novel "Variable Star".Heinlein's posthumously published nonfiction includes a selection of correspondence and notes edited into a somewhat autobiographical examination of his career, published in 1989 under the title "Grumbles from the Grave" by his wife, Virginia; his book on practical politics written in 1946 published as "Take Back Your Government"; and a travelogue of their first around-the-world tour in 1954, "Tramp Royale".The novels "Podkayne of Mars" and "Red Planet", which were edited against his wishes in their original release, have been reissued in restored editions.
