Earth's Last Citadel

The story begins in the Tunisian desert. WW2 rages & Alan Drake of American Army Intelligence is struggling to complete his latest mission. His job is to get the Scots scientist Sir Colin Douglas out of German hands & to Allied safety. The two fugitives are walking crosscountry. They're pursued by two Nazi agents: Karen Martin, a sly, ruthless but charming woman of mixed race, & Mike Smith, an Americanized German with a history in racketeering & an instinct for killing. All four simultaneously pass over a crest & come upon each other & an ovoid craft half buried in a crater. The craft is glowing with heat like a meteorite, but its surface is perfectly smooth as if its plunge has left it unharmed. The two parties draw weapons. A standoff occurs, but suddenly, as if commanded by telepathic control, all four walk into the craft. The craft buries itself in the ground & Drake is dimly aware of strange dreams, of an alien creature hovering in a doorway & of time passing. When all four awake they find themselves transported far into the future. What strange adventures & what dangers await the four 20th century travelers? Will they ever return?
