For the first time in trade paperback, one of Robert A. Heinlein's final novels, completed by Hugo-winning author Spider Robinson

At his death in 1988, Robert A. Heinlein left behind a legacy of novels and short stories that almost single-handedly defined modern science fiction. But one of his 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, only to set it aside to focus on other novels. The detailed outline and notes Heinlein created for the project lay forgotten for decades, only to be rediscovered almost a half a century later. The Heinlein Estate authorized Hugo and Nebula award-winning author Spider Robinson to expand the outline into a full-length novel. The result is vintage Heinlein, faithful in style and spirit to the Grand Master's original vision.
