Ramage and the Renegades (Lord Ramage Series #12)

Nelson's crews are standing down and Ramage is on leave when he received secret Admiralty orders to inspect the small island of Trinidad off the coast of Brazil. Reaching the island's shores, Ramage and the crew of the Calypso fetch up in a battle to free several captive merchant ships—and a beautiful woman passenger—as they cross swords with bloodthirsty pirates.
