Countersolar! Richard A. Lupoff

It's 1942, the Titanic is still cruising and the world is at peace. Suddenly, there's a distress call from Counter-Earth, our twin planet on the other side of the sun. A ship is launched with Albert Einstein and the first woman pro baseball player - Babe Didriksen - on the crew. But at the same time, Juan Peron and his lovely Evita launch a faster ship from Argentina, armed for war in space. Who will reach Counter-Earth first? A brains-and-baseball alliance of American heroes? Or an Argentinian temptress and her fascist husband? Reviewed as 'audaciously inventive...a wild romp through a very strange universe.'
