Opar – the Atlantean colony in the heart of Tarzan’s Africa; in the words of Edgar Rice Burroughs, a hidden city of  ‘gold and silver, ivory and apes, and peacocks.’ And –  the starting point of this story,  twelve thousand years ago, when Africa had in inland sea and a high civilization bloomed along its forgotten shores, when lost empires flew their time-vanished banners, and deeds of daring were commonplace. Hadon, son of ancient Opar, whose claim of the throne launches him on a dangerous adventure. Cover art by Julek Heller.
