At seventeen, Aurelia Everly thought she knew her family better than anyone. Then her parents announce they are leaving the country for six months—and leaving her under the supervision of Lucien Ardent, her father’s closest friend. At thirty-two, Lucien is everything Aurelia remembers: composed, intelligent, respected, and impossible to read. But his arrival comes with something she never expected—secrets. A mysterious message warns Aurelia that her father hasn’t told her the truth about what happened seven years ago. Then a strange note leads her to a locked section of Asteria Academy, where she discovers an old record containing three familiar names: her father, Lucien, and the family’s lawyer. Now Aurelia has questions no one wants to answer. Why did they have access to a hidden room? What happened seven years ago? And why is someone desperately trying to stop her from finding out? As Aurelia follows clues that were never meant to be discovered, she realizes the mystery reaches far beyond her school. Someone has been protecting a secret for years. And the promise that started it all may finally be ready to break.
