Maria Vale thought she knew her life—until she was kidnapped and taken to the luxurious Blackwood estate, where three powerful brothers, Adrian, Roman, and Lucien Blackwood, become her captors. They claim her father betrayed their family and left behind a mysterious black key capable of unlocking secrets powerful enough to destroy empires. But Maria soon discovers that her father's story is only the beginning. Her mother, whom she believed was lost forever, may still be alive. The man she called her father may not be her biological father. And the dangerous Victor Crowe claims to be the man who truly fathered her. Trapped between three brothers who each develop complicated feelings for her, Maria must uncover the truth about her identity before the people hunting her find her first. But in a world built on lies, blood, betrayal, and forbidden desire, Maria must decide one thing: Will she remain the prisoner—or become the queen of the kingdom that imprisoned her?
