Tarzan And The Ant Men by Edgar Rice Burroughs

Swept into a remote, hidden realm inhabited by a diminutive, antlike people, a mighty jungle lord becomes a living giant among them and is drawn into their rivalries and power struggles; using his strength, intelligence, and knowledge of warfare he navigates intrigue, aids the oppressed, confronts hostile factions, rescues those in peril, and ultimately reshapes the destiny of the tiny kingdom before returning to his life in the jungle.
