Rowan Hale, a scent-forensic auditor born wolfless and pheromone-null, lives as a despised "blank". When the Moon-Bond Agency tries to take her sister Mara as a living stress vessel, Rowan bursts in with an audit warrant. She accidentally accesses the closed twin mind-link shared by lord Kieran Vale and strategist Elias Voss. Bound by a thirty-day audit contract, she fights elite conspiracies and removes the silver implant suppressing her hidden power. She uncovers the grim truth of her imprisoned mother. With forensic expertise and her awakening Moon Arbiter abilities, Rowan overcomes deadly traps, unites survivors, and rises to defy Selene Crowe's tyrannical Moon-Bond regime.
