The year is 1803. Swashbuckling, ribald, and irreverent hero Ethan Gage has outsmarted wily enemies and survived dangerous challenges across the globe, from the wilds of the American frontier to the pyramids of Egypt. 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 Cortés'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.

Caught between the French and the rebel slave forces, Ethan and Astiza are in a race for gold and glory that will thrust them into the center of a bloody struggle for freedom as they try to rescue their son. And this time, Gage's luck may be running out.

Brilliantly combining science, history, mythology, and wit, William Dietrich has woven a larger-than-life tale that sees Ethan embroiled in the Napoleonic era's ideals, opportunism, and inventions, which gave rise to the modern world. Filled with intrigue, voodoo, a hurricane, violent political unrest, and unexpected passion, The Emerald Storm is Dietrich's most captivating work to date.
