The Blood Pact Game

Victor, a vampire king of the North weary after a thousand years, secretly posts a huge bounty for his own assassination. Ella, an orphan raised as a killer by the blood-hunting Silver Blade, takes the job to buy her freedom, but her infiltration fails. Instead of killing her, Victor binds her to him with a blood covenant that gives her power and a chance to turn against him. Ella plays the obedient servant while waiting for her opening, yet as they share their days and nights, something unexpected grows between them.
