In October 1815, after losing the Battle of Waterloo, Napoleon Bonaparte was banished to the island of Saint Helena. There, in one of the most remote places on earth, he lived out the final six years of his life. On this lonely island with no chance of escape, he found an unexpected ally: a spirited British girl named Betsy Balcombe who lived on the island with her family. While Napoleon waited for his own accommodations to be built, the Balcombe family played host to the infamous exile, a decision that would have devastating consequences for them all. Thomas Keneally recreates Betsy's powerful and complex friendship with the man dubbed The Great Ogre, her enmities and alliances with his remaining courtiers, and her dramatic coming-of-age.
