by Hendricks, Greer
Jessica Farris signs up for a psychology study expecting a few easy questions and a paycheck, but the experiment quickly shifts into something far more invasive. Dr. Shields, the researcher, begins demanding increasingly personal secrets, turning the study into a high-stakes power struggle that forces Jessica to confront her own moral boundaries. The prose is tight and claustrophobic, trapping you inside Jessica's head as her sense of reality begins to fracture. It is a slow-burn descent into paranoia where you never quite know who is pulling the strings or what the end game is. If you enjoy books that make you question the reliability of the narrator and find yourself shouting at the page because of a character's questionable decisions, this will keep you awake late into the night.
Since you enjoyed the unsettling power dynamics and the constant state of unease in An Anonymous Girl, our curated list focuses on stories where trust is a liability. We selected these titles because they excel at the same psychological warfare and unreliable perspectives that make a mystery feel personal rather than procedural. Whether it is through the lens of a clinical experiment or a domestic nightmare, these books prioritize the slow, agonizing reveal of hidden motives. If you want to continue exploring the dark side of human observation, these stories will satisfy that itch for complex, layered manipulation.
