One More Breath Before I Drown

The year is 1743 and King Philip V of the Spanish Empire has enlisted Bernardo Rivera to vanquish all of the merfolk in the Caribbean to cleanse the world of Satan's children. Bernardo's daughter, Isadora, finds herself in a tricky situation after she and her mother are sacrificed to the merfolk for entrance into an isolated domain, but she is spared from death by a merman who harbors some unusual secrets of his own. Ten years pass and the situation doesn't improve. Mermaids and mermen are still devouring sailors and their ships whole; not to mention British invasions on Cuba, Isadora's homeland, have stirred up mentions of war in Europe as Spain, France, and England struggle for the New World's land, power, and wealth. Oh, did I mention the scaly love interest? Yeah, there's always one of those.
