On the other side of the sun, opposite our earth, is a world we never see Counterearth. In every way it's identical to ours...almost!
Albert Einstein, Juan (and Eva) Peron, Babe Didrickson and Sir Oswald Mosley are off on a wild race to Counterearth. It's all action and excitement against a historical background - in fact against "two" historical backgrounds - detailed enough to intrigue any history buff. It's January 1942; Cordell Hull is President of the United States; and the good guys take off in their spaceship, "Manta," from the deck of the SS "Titanic," steaming back from Liverpool to New York with thousands of New Year's revellers on board.
