The Pirate Rogue by Anna Markland

Capitán Santiago Velázquez falls afoul of the Spanish Inquisition after a disgruntled lover falsely accuses him of perverse tendencies. Forced to flee to the Americas, he follows in the footsteps of his pirate ancestor and plunders ships the length and breadth of the Spanish Main. Captured by the Spanish governor of Florida in the last days of the Seven Years War with the British, he agrees to attack Royal Navy vessels under the aegis of Letters of Marque. In exchange, he secures a pardon for himself and his crew.

Valentina Melchor is trapped in St. Augustine with her father, the governor, when Florida is ceded to Britain by the Treaty of Paris.
The turmoil caused by the end of the war is Santiago’s opportunity to flee, but he risks his life and his ship to rescue Valentina, despite his resolve to never trust a woman again.
