In a vividly drawn India of the late 19th century, orphan Kimball O'Hara is on the cusp of manhood. Living as a beggar, it isn't until Kim befriends an aged Tibetan Lama that his life transforms: the old man is on a quest to find the legendary River of the Arrow and achieve Enlightenment, and together they embark on an adventure through this impoverished, beautiful, chaotic nation in the grip of the Great Game, the conflict during which the British and Russian Empires raced to control Central Asia.

But when Kim becomes a pawn in the Game, he must face the most difficult choice of all: his companion or his country?
