Variable Star

Editor’s Preface

In Robert A. Heinlein’s Stranger in a Strange Land there is a story about a Martian artist so focused on his work that he fails to notice his own death, and completes the piece anyway. To Martians, who don’t go anywhere when they die but simply become Old Ones, the burning question was: should this work be judged by the standards used for art by the living, or for art by the dead?

A similar situation occurs here for one of the first times on this planet. This book is a posthumous collaboration, begun when one of its collaborators was seven, and completed when the other was seventeen-years-dead. Spider Robinson discusses this at length in his Afterword, but a brief explanation at the start may help readers to better appreciate what they’re reading, and to decide by what standards they should evaluate it.

After the passing of Robert Heinlein’s widow, Virginia, in 2003, his archivist/biographer discovered a detailed outline and notes for a novel the Grand Master had plotted in 1955, but had never gotten around to writing, tentatively titled The Stars Are a Clock. Heinlein’s estate executor and literary agent decided the book deserved to be written and read, and agreed that Spider Robinson was the only logical choice to complete it.

First called “the new Robert Heinlein” by the New York Times Book Review in 1982, Robinson has been linked with him in the reviews of most of his own thirty-two award-winning books. The two were close friends. Spider penned a famous essay demolishing his mentor’s detractors called “Rah, Rah, R.A.H.!,” and contributed the introduction to Heinlein’s recently-discovered 1939 first book, For Us, the Living.

It was a pairing as fortuitous as McCartney and Lennon. You are about to read something genuinely unique and quite special: a classic novel fifty years in the making, conceived in the Golden Age of SF by its first Grand Master, and completed in the Age of Cyberspace by one of his greatest students. Variable Star is Robert A. Heinlein’s only collaborative novel—and we believe he would be as proud of it as Spider Robinson is, and as we at Tor are to publish it.
