"The Monster Men" by Edgar Rice Burroughs is a science fiction novel published in 1913. Professor Arthur Maxon retreats to a remote island in the East Indies to conduct forbidden experiments in creating artificial human life. As he grows increasingly obsessed with perfecting his creations—particularly Number Thirteen—dark forces conspire around him. Pirates, treasure hunters, and his own assistant threaten his daughter Virginia, while the handsome but supposedly soulless Number Thirteen may be her only hope for survival in this Frankenstein-inspired adventure.
