The emerald storm

the long version

"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."--Publisher
