Flight to Opar is the second of three adventures that Farmer planned set many thousands of years prior to Tarzan's adventures in that lost city-colony of Atlantis. It's preceded by the equally enjoyable Hadon of Ancient Opar, and this one continues the story that began there fairly closely; he had not finished the third book at the time of his death, and it was completed by another writer and published posthumously by a different publisher. It's a pretty good pastiche of Edgar Rice Burroughs, and also serves as an homage to many of H. Rider Haggard's African adventures. Farmer adopted the Burroughs style and formula, though the character of Hadon is not as likable as Burroughs'. (The book is copyrighted by Farmer, not the Burroughs folks.) The DAW first printing of Flight to Opar had a vibrant cover by Roy G. Krenkel, but they put one by Ken Kelly on the reprint. They did keep the several nice interior illustrations that Krenkel drew.
