The Booker-winning Australian writer launches his new novel. On the island of St Helena in the South Atlantic Ocean, Napoleon spends his last years in exile. It is a hotbed of gossip and secret liaisons, where a blind eye is turned to relations between colonials and slaves. The disgraced emperor is subjected to vicious and petty treatment by his captors, but he forges an unexpected ally: a rebellious British girl, Betsy, who lives on the island with her family and becomes his unlikely friend.
