Six hundred years of immortal friendship. One bite that changes everything. Ancient vampires Aster Castelmar and Sylvia Maroven have been inseparable for six centuries. They’ve survived inquisitions, wars, collapsing empires, the industrial revolution—but now they face their most challenging obstacle yet: New York City rental prices. With only a week left in their last apartment, the broke best friends hatch a bold get-rich scheme: enthrall a billionaire. With Sylvia’s charm, Aster’s raw strength, and a dash of vampiric hypnosis, the plan should be foolproof. Then Sylvia bites Aster. It’s meant to be a joke, a fleeting thrill between lifelong companions. But instead, the bite awakens an ancient bond reserved for soulmates, forcing them to face feelings they’ve spent centuries denying.
