Jimson had twenty years to live. Or one. Twenty if he stayed in space-normal, where his disease could be treated. One year if he followed the Starcaptain into the Hype - the "not-space" that trip was the only way to the stars, where jeweled voyagers sailed the light-centuries in color-shifting ships; humankind's outriders, star-burned lovers to a Universe heavy with stars... This is the story of that year. (from the back cover of the first edition)
