Variable Star Hardcover - 2006

Robert A. Heinlein is universally acknowledged as modern science fiction's greatest author. At his death, in 1987, he left a legacy of books and stories that has profoundly influenced the course of the field for generations.
But one of Heinlein's most ambitious works was never finished. In 1955, he began work on a novel to be titled "Variable Star, " completing a detailed outline and making extensive notes for the book, only to set it aside to focus on other novels, including "Tunnel in the Sky" and the Hugo Award-winning "Double Star." For more than half a century, the work lay forgotten among Heinlein's papers. Then, on its rediscovery a few years ago, the Robert A. Heinlein Trust selected an author to finish the work.
The author chosen for the project was, appropriately enough, a writer "The New York Times" has hailed as "the New Robert Heinlein"--Spider Robinson, the Hugo and Nebula Award--winning author of such modern SF classics as "Stardance" and "Melancholy Elephants." Faithful to the spirit of Heinlein's original vision, and laced with contemporary touches that will appeal to modern readers, "Variable Star" is a rare treat for the Grand Master's many fans.
Profits from the book will help fund the annual $500,000 Heinlein Prize for innovation in commercial manned spaceflight, a goal Mr. Heinlein considered crucial to humanity's long-term survival.
