A secret that will destroy an empire. Sienna Brooks thought she was marrying the man of her dreams. But on the night of her engagement party, a drunken haze leads her to the wrong guest bedroom—and into the arms of a devastatingly dominant stranger. She wakes up marked, ruined, and terrified, only to discover the man she gave herself to is Roman Hargrove: a ruthless billionaire and her fiancé’s closest friend. Roman despises her, convinced she’s a calculating gold digger playing his best friend for a fool. He promises to watch her every move, waiting for her to slip up. But the slip-up isn’t a lie—it’s a positive pregnancy test. Publicly humiliated, fired from her job, and thrown onto the cold streets by her furious fiancé, Sienna is left with nothing but the innocent life growing inside her. To prevent a catastrophic war between the two powerful men, she swears to take the father's identity to her grave. But Roman is a man who notices everything. And when the cold-hearted billionaire discovers the truth, he won't just demand his hidden heir. He’ll demand the very woman he swore to destroy.RomanceForced ProximityBillionaireCEOOne-night StandGoodgirlContemporary139 ChaptersOngoingMay You LikeThe Billionaire I Built, The Husband I BuriedViciously Off-LimitsThe Vanguard's CageHis After-Hours UltimatumHis Sweetest Sin: Under the Billionaire's CommandHis Untraceable ObsessionThe Escort's Billion-Dollar Bridal TrapAltar of Lies: Bound to the Ruthless HeirCollateral BrideRead now
