L. Sprague deCamp

The Virgin of Zesh In which a beautiful woman, a mind-drunk poet, and a super-sober scientist must fight for their lives on a planet occupied by weird cultists from the Earth and bizarre varieties of humanoids from all over the galaxy. The Wheels of If In which a young lawyer is trapped in a sense-shattering shuttle among alternative worlds of possibility, and lands at last in an America that has been colonised by Norsemen and divided between two great warring empires - one white, one Indian.
