Tarzan and the Castaways (Tarzan, #24)

Stranded on an uncharted Pacific island, Tarzan was forced to take command of an ill-sorted party—English aristocrats, a Dutch officer, a woman of doubtful reputation—to insure their safety from a band of mutineers led by a madman. A lost colony of Mayans, avid for potential victims for their barbarous human sacrifices, only added to the danger. But the Lord of the Jungle had unexpected allies...Cast away with his band was a shipment of African animals unknown to the island, striking terror in the hearts of Mayans and mutineers alike—but old friends and familiar antagonists to the man brought up among them...Tarzan of the Apes.
