All She Ever Wanted

Bridgerton meets The Princess Bride…
Aurelia Danby always loved fairy tales and heroes. But fanciful books made her ridiculous, so they were taken away, leaving her shackled to sensibility and high society.
She would have been hopelessly resigned to being a rich man's wife were it not for William Kingswood, her handsome and very unavailable neighbor who once saved her life as a child. He's spent the last ten years writing to her of his adventures in exchange for keeping his secret—that while he's a gentleman, he also rules the Atlantic as the infamous pirate, Captain Copson.
Aurelia is desperately in love with him, but sensible girls don't fall for pirates. She's also eager to escape her arranged marriage, and sometimes pirates are a ridiculous girl's best (if not preferred) option.
When Captain Copson causes an international scandal by stealing Aurelia from her royal fiancé, Aurelia embarks on an adventure to rival her favorite tales, filled with treasure, poker games, mermaids, battles, sea monsters, grand theft, French people, and wild schemes—including thwarting her fiancé who will do anything to get her back.
Aurelia Danby's heart has only ever belonged to adventure—and her very troublesome captain.
