They walk the halls, cloaked in beauty and danger. Natalie never believed in legends... until she met Adrian—the devastatingly seductive man with eyes that promise ruin and lips that taste like sin.

To fall for him is to challenge bloodlines, defy ancient law, and risk waking a power buried long before she was born. But some flames aren’t meant to be tamed. Some touches aren’t meant to be denied. And some loves? They were made to set the world on fire. Sink your teeth into this steamy, forbidden vampire romance where the rules were made to be broken—and desire always wins.

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.

Haunted by visions of a powerful witch from centuries past, Seraphina flees with her friend Lira, only to learn her magic is mutating beyond control. Forced into an uneasy alliance with Kael, she discovers that the mark connects them not as enemies, but as halves of one prophecy a curse meant to either unite or destroy all realms. As the world prepares for war, Seraphina is betrayed by her own kind and hunted by Demon Hunters led by the relentless Captain Ryn. Meanwhile, Kael hides a devastating secret: his father, King Azarel, plans to use Seraphina’s blood to merge the demon and human worlds forever.
