The Monster Men by Edgar Rice Burroughs, Science Fiction

Cornell University professor Arthur Maxon, who has been experimenting in the creation of artificial life, travels with his daughter Virginia to one of the remote Pamarung Islands in the East Indies to pursue his project. Their departure is noted with interest by a young man, Townsend J. Harper, Jr., who is quite taken with Virginia and determines to find out where they are going. In Singapore, Maxon commissions Dr. Carl von Horn to take them the remainder of the way to their destination in his yacht the Ithaca, and then to assist him in his experiments. On the island the group fights off a pirate attack and builds a fort.
