Morgan is just trying to survive her cousin’s destination wedding in Bermuda. She didn’t come prepared for emotional damage, and she certainly didn't expect the biggest drama of the weekend to involve a head injury, a blocked tunnel, and a very confusing run-in with three dudes dressed like they raided a Pirates of the Caribbean casting call. Turns out they’re not LARPing. They aren't actors. It's not a fun sunset cruise. No. They’re privateers. Like, real ones. From the actual year 1725. And Morgan? She’s stuck. She may have a pretty good handle on how to survive in the wilderness, thanks to her ex-Green Beret dad. But eighteenth-century ships, sexist crewmates, and suspicious captains aren’t exactly her area of expertise. Especially not Flynn, the broody, grumpy, maddeningly handsome Captain who might rather toss her overboard than deal with whatever disaster she’s brought onto his ship. But as danger closes in, from rival ships to secrets Morgan didn’t mean to bring with her, she’ll have to find her place in this brutal new world. That is… if she doesn’t drive Flynn to keelhauling her first. Or fall for him. Maybe both. Adventure, slow-burn tension, and fish-out-of-water chaos collide in this swoony, high-stakes romantic tale across time. For fans of enemies-to-lovers, pirate drama, and heroines who don’t know when to shut the fuck up.

Robert Blackwell promised to marry me, then postponed it thirty-eight times. The fifth time, a car crash broke eight of his ribs, and I signed seven critical-condition notices. The tenth time, on the way to get our marriage license, he and the car were thrown into the sea, and his suit was torn apart by sharks. By the thirty-eighth time, his heart disease had worsened and his life was hanging by a thread. Eight months pregnant, I changed flights three times and flew twenty-three hours across half the world to find him. When the door opened, a little boy who looked exactly like him lifted his face and said, "I thought Mom was back." Robert rushed out barefoot, panic written all over his face. I turned around and saw my best friend of twelve years standing behind me with a key in her hand. The little boy ran to her and threw himself into her arms, calling her Mom. So the fiance I had waited seven years for was my best friend's secret husband all along. "I will not wait through these thirty-eight near-death weddings anymore." "Robert, I do not want you either."
