At nineteen, y/n is assigned to observe the most feared patient ever admitted to Blackridge Psychiatric Institute—a thirty-two-year-old cartel lord named Lucien Moreau. Every therapist before her has quit, refused to return, or been reassigned, leaving Lucien with a reputation as untreatable. Determined to remain professional, y/n quickly discovers that beneath his ruthless reputation lies a man haunted by violence, guilt, and a life he can never escape. As their weekly sessions blur the line between doctor and patient, dangerous secrets, rival cartels, and impossible feelings threaten to destroy them both—forcing Lucien to choose between protecting the only person who has ever truly seen him or walking away before his world consumes her.
