L. Sprague deCamp 
Virgin of Zesh [EPUB ebook] 

Welcome back to the planet Krishna – a wilderness of blue woods under three moons, where square-riggers sail the treacherous inland seas, where fierce humanoid natives with feathery antennae cross swords in endless war, and where a Terran outside the confines of the spaceport is strictly on his own!The Virgin of Zesh is the fifth of L. Sprague de Camp’s Krishna book – interplanetary romance in the tradition of Edgar Rice Burroughs’ Martian Tales.
