BloodTide (season 1)

When Ella Andrews stumbles into a stranger at a nightclub, she doesn't expect it to end in marriage. She certainly doesn't expect it to end in a war.
Ella has spent her life feeling like something in her didn't quite fit - until the night she meets Kedan Dyre: billionaire, ruthless, and centuries older than he looks. Their whirlwind courtship ends in a wedding neither of them fully understands, and on their wedding night, Kedan reveals what he really is. It's the same night the ocean starts calling to something buried in Ella's own blood.
She isn't human. She never was.
As Ella awakens to a heritage older than the treaty that bound her husband's bloodline to her mother's, she's pulled into a world of ancient houses, blood politics, and enemies who see her as nothing more than an asset to be claimed - or a threat to be erased. Kedan will burn down everything he's built to keep her safe. But the deeper Ella goes, the more she realizes the danger isn't only coming from outside their marriage. Some of it has been hiding in her own family for twenty-six years.
A sister who isn't what she seems. A mother believed dead who might still be watching. A father-in-law who buried more than secrets. And a child growing inside her that neither bloodline has ever produced before one that every faction wants a claim to before it's even born.
blood tide is a dark, possessive, slow-burn paranormal romance about the cost of love built on centuries of blood, the family you're given versus the family that chooses you, and a woman who has to decide how much of herself she's willing to become to protect everyone she loves.
Some tides don't just pull you under. They bring you home.'
