He was supposed to be her terrifying boss. He became her ruthless mate. Senior forensic auditor Clara Bailey made the ultimate mistake: she looked too closely into Julian Sterling’s private accounts. Cold, lethal, and devastatingly handsome, Julian rules Wall Street by day and the supernatural underworld by night. When he catches Clara digging into his secrets, he doesn't call the police. He locks down the skyscraper, traps her in his penthouse fortress, and marks her as his fated mate. Julian is fiercely protective, violently possessive, and used to absolute obedience. But Clara refuses to break. As their proximity ignites a scorching, undeniable desire, Clara's own dormant royal frost magic awakens—along with an unplanned royal pregnancy that ties their souls forever. Now, ancient enemies from across the Atlantic are marching on Manhattan to steal their unborn child. To Julian, the choice is simple: anyone who dares look at his pregnant Queen will die in the dark. A dark billionaire shifter romance packed with forced proximity, a lethal Alpha protector, and a fated bond that defies an empire.
