The year is 1803. Swashbuckling, ribald, and irreverent hero Ethan Gage has outsmarted wily enemies and survived dangerous challenges across the globe. Now the rakish hero finds himself in the Caribbean with his wife, Astiza, on a desperate hunt to secure the lost treasure of Montezuma - a legendary hoard rumored to have been hidden from Cortes's plundering Spanish conquistadors. Hot on his heels are British agents who want the gold to finance a black slave revolt in Saint-Domingue, robbing hostile France of its richest colony. The French, too, seek the treasure for the secrets it contains, the key to an incredible new means of invasion that can ensure Britain's defeat - on its own land.
