Elara, the last pure-blood vampire, awakens in the modern world after centuries of slumber. To obtain the "elixir blood" she needs to survive, she opens a mysterious club called Evernight under the guise of a life-energy consultant. Kaelen Blackwood, a business emperor slowly dying of an undetectable poison, is brought to her by his stepmother. Elara treats him with blood as her price, and in the teasing, testing sessions the two fall for each other. She unravels a cursed painting, a corporate scandal, and a family conspiracy—then uncovers the Twilight Era, a secret organization hunting her for immortality. In the end, Elara crushes every villain and the European vampire council, forges a blood bond that crosses life and death, and builds a dark empire at Kaelen's side.
