The Monster Men - Edgar Rice Burroughs

Dr. Arthur Maxon has a dream: to create an artificial human being! His first twelve experiments have resulted only in grotesque, subhuman monsters. But Number Thirteen is perfect, and will make an ideal mate for Virginia, Dr. Maxon’s only daughter. But his monstrous plan goes awry when it is disrupted by pirates and Maxon’s duplicitous assistant, Carl von Horn. - Summary by Mark Nelson
