As the Green Star Rises 

In the marvel-adventure sagas of Edgar Rice Burroughs, Otis Adelbert Kline, and John Norman, has there ever been a situation such as befell the Earthling who found his way to the world under the Green Star? For while his real body lay crippled and silent under the sun of old Earth, his mind occupied the vigorous body of a young primitive on that alien planet of mighty trees, floating cities, and unmapped limits. And in that guise he had found incredible friends, a royal love, and inhuman and superhuman enemies. But no matter what predicament he was in – and as this book starts he is alone, abandoned on an uncharted sea – his courage never flagged though the greatest of risks would confront him as the Green Star rises.
