The Big Jump: Leigh Brackett

Stardrive - access to the farthest reaches of the galaxy! Ballantyne created and tested the new engines. And he returned from the stars...alone, dying of a ghastly new form of radiation. And no-one can discover what has happened to the crew. But Arch Comyn is determined to know what did happen on this first trek into the unknown. There is only one alternative and too many obstacles. To learn the truth, Comyn must make the perilous journey himself and come face to face with the horrifying secret that waits mankind beyond...the Big Jump. Cover art by Ron Walotsky.
