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 New York City rental prices. After decades of spending, they’re broke, unemployed, and they need money fast. So they do what any sensible immortal criminals would do, and pivot to white collar crime. Their plan is embed themselves in a tech startup, manipulate a billionaire oil heir, take his money, and vanish. It’s a great scheme, fullproof like all of their previous adventures. Well, it would have been foolproof, if Sylvia hadn't bitten her. The bite should have been meaningless. A joke between lifelong friends. Instead, it triggers an ancient vampire bond meant for lifelong partners, leaving Aster unraveling… and begging for more.
