At twenty-two, Ottilie "Tilly" Fleur Vittorie Oster expects a quiet life of baking and archival work—not a summons to an isolated Gothic manor on the Yorkshire moors to hear her estranged grandfather’s will. The terms are non-negotiable: to inherit a single penny, Ottilie must live at Blackwood Manor for ninety consecutive days alongside Draco Malfoy—a forty-two-year-old, heavily tattooed former black-ops enforcer with scarred knuckles, dead-cold gray eyes, and blood on his hands. If either leaves early, the entire fortune defaults to Ottilie’s greedy, ruthless uncle. Ottilie wants to walk away—until Draco reveals her grandfather was poisoned, and hired killers are already closing in to eliminate the last surviving heir. Trapped together inside a sprawling estate cut off by winter storms and family secrets, Ottilie refuses to blindly trust the terrifying mercenary sharing her roof. Yet as assassins breach the gates and a deadly laundering conspiracy comes to light in the manor’s archives, Draco’s hair-trigger brutality becomes the only thing standing between Ottilie and a shallow grave. "You shouldn't trust me, Miss Oster. If you did, I'd assume you were an idiot."
