For Amber Fang, life used to be simple: study library science by day, read by night and, when she got hungry, enjoy an ethical meal straight from the jugular. Her mother taught her well. It's just good manners for vampires to eat only murderers. But now her mom has vanished, and Amber is alone. Her contract work as an assassin has been terminated. But the secret organization ZARC is still trying to hunt her down, using algorithms, drones, and a murderess with metal hands. Through the dark web, Amber learns that her long-lost mother has been "disappeared" to a secret compound in Antarctica. When Amber arrives and pries open a door to investigate, what she discovers shocks her to the core. And it will change her life forever. If she survives.
