At his death in 1988, Robert A. Heinlein left a legacy that almost single-handedly defined modern science fiction. But one of Heinlein's masterpieces was never finished. In 1955, he began work on Variable Star, a powerful and passionate tale of two young lovers driven apart by pride, power, and the vastness of interstellar time and space. Now, the Heinlein estate has authorized award-winning author Spider Robinson to expand his outline into a full-length novel. And the result is vintage Heinlein.
