The Brazen Shark — David Lee Summers

Pirate captain, inventor, and entrepreneur Onofre Cisneros sweeps his friends Fatemeh and Ramon Morales off to Hawaii for their honeymoon. Once there, a British agent makes Cisneros an offer he can't refuse and the captain must travel to Japan. Wanting to see more of the world, Ramon and Fatemeh ask to accompany the captain only to find themselves embroiled in a plot by samurai who steal a Russian airship, hoping to overthrow the Japanese emperor.
