Eons from now, Man will hurtle through the void in gravity-defying ships across light years of distance to far-flung planets . . . And more staggering yet, he will colonize these islands in the unimaginably vast ocean of space. There will be world, such as:

LANI III -- a glacier-land warmed by man

XOSA II-- a shining desert made green by man

LOREN II -- an inferno of beasts, tamed by man

The fascinating and heroic story of a trail-blazer to the unknown -- outer-space service officer Bordman, who uses incredible knowledge and skill to make the star-flung outposts of civilization ready to receive new, vast surges of humanity!
