Islands of Space. Arcot, Wade and Morey Book 2

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