Married to a Pirate: A Dark Fantasy Romance (Romancing the Seas #1) by Athena Rose

"You enslaved me!"
"Nay, I liberated you, my lady. And there will be more liberating to come if you behave."

Imagine you’re engaged to marry a prince but your father gambles away your dowry and sells you to a pirate captain who you are forced to marry.
He’s cold and ruthless so you run away but then you get captured by more pirates and just as they’re about to hurt you, your pirate husband shows up, with his sword to the captain’s throat as he roars,
”Touch my wife and I will destroy you all.”
