Monster Men

They called him Number Thirteen, the latest and best of Dr. Von Horn's attempts to make life from lifeless chemicals. He found himself an almost-human on Von Horn's hideaway jungle island off the coast of Borneo. He saw the monsters that had preceded him and grew used to those dreadful travesties of humanity. Not until Number Thirteen met the American girl who was Von Horn's unwilling prisoner did he realize how different he was from the others. Because, monster or not, he turned against his master and threw in his lot with the girl and his friends in their desperate effort to escape the island of terror. The story of THE MONSTER MEN is an Edgar Rice Burroughs novel of savages, primitive monsters and jungles in the best Tarzan style.
