Twenty‑two‑year‑old Ava Hart enters a mysterious job interview to pay off her late mother’s debts, only to end up as a blood‑source commodity in a vampire underground auction. Just before she falls into the hands of the most dangerous bidder, Lucian Blackwood, the enigmatic ruler of the Night Folk, buys her for a hundred‑million‑price and forces her to sign a blood pact. Forced to move into his manor, Ava discovers the arrogant, dangerous man harbors a staggering secret: she is the sole survivor of the massacred Hart family from a century ago. To claim the throne, Lucian must wed an heir of Hart bloodline. Both resist this fated marriage, unaware the one they seek and reject is each other. From blood pact to symbiosis, from suspicion to standing side‑by‑side, Ava must awaken her ancestral blood power. Together with Lucian, she faces power intrigues among the Night Folk, ancient abyssal beasts, and the ultimate choice between protection and sacrifice.
