Islands of Space

"Arcot, Wade, Morey, and their computer, Fuller, put together a ship which will travel faster than light . . . they give us what may have been the first space-warp drive. The concept was simple; to make it plausible wasn't -- unless you were John Campbell.

"With this out-of-space drive they hightail it among the stars. They locate the fugitive planets of the Black Star . . . find a frozen cemetery-world of a lost race . . . then head out for another galaxy . . . and wind up in a knock-down-drag-out interplanetary war in the other galaxy."
