The Man Who Mastered Time

<b>From the first page of the Ace Double:</b> "A classic adventure in the far future - It took what seemed but half a day's traveling to traverse the 28,000 years that separated Loto Rogers from the most beautiful girl he had ever seen. He had expected to find mighty cities and a flowering civilization in that future world, but instead he found only ice and snow - and Azeela. <p>Thought Loto had intended only to visit, he saw then that he alone could help the survivors of the centuries' incredible savages. And so <i>The Man Who Mastered Time</i> faced the one problem that his super-science could not answer - the mastery of the world's final show down."
