Set in early nineteenth-century France, this sweeping adventure novel follows a young sailor who is falsely imprisoned for a crime he did not commit, spends years in a brutal island fortress, escapes with a vast hidden fortune, and reinvents himself as a mysterious and fabulously wealthy count — methodically engineering the ruin of each man responsible for his betrayal. It is one of the longest and most beloved adventure stories ever written, driven by themes of justice, revenge, and whether vengeance can ever truly bring peace.
