An AFB 5-book sf multi-pack: The Maracot Deep, When the World Screamed, Starship Troopers, The Venus Venture, Earth Unaware

Five novels of speculative fiction, the first being a novel of Atlantis (haven't they found that damn place yet?), the second a collection of seven short stories (the first of which is the sf title story, the other six "ranging from tales of mystery to yarns of the bare-knuckle prize-ring"), the third a classic from one of sf's Big Three, the fourth a novel of mankind "galloping towards the stars," and the fifth giving us the story of a being whose "unearthly power could destroy the world" (considering the way things are going, it can't happen a minute too soon, either). Size: 12mo - over 6¾ - 7¾" tall.
