Pious by Day, Dominant by Night

Claire Vanderbilt has thirty days to keep her reputation spotless. If she makes it to her 21st birthday with zero scandals, she inherits a billion-dollar trust fund. If not? Her cheating father and his smug illegitimate son take everything. So Claire plays the part: modest dresses, prayer books, virginity pledge and all. But every night, she puts on a lace mask, picks up a whip, and becomes """"The Mistress""""—the most feared dominatrix in the city's underground club scene. Then a stranger crashes into her private room. Killian Thalassa—transfer student, Nordic "old money"heir, and actually the son of the Deep Sea King. He's on land to recover a stolen ocean relic. Problem is, his bloodline is going haywire, and the only thing that calms it is Claire's scent. They strike a deal: she lets him stay close, he plays her bodyguard. In public, they're strangers. In private, his glowing tentacles are wrapped around her waist and neither of them is complaining. She uses him to destroy her stepbrother. He uses her to infiltrate the three families who stole his birthright. But somewhere between the fake moans and the real orgasms, the line between "using"and "wanting" gets ripped to shreds. Until Claire realizes her "guard dog" isn't just a monster—he's a monster who'd tear apart an entire underwater kingdom just to kneel at her feet.
