The Locked Ward is a fast-paced, atmospheric psychological thriller that intertwines family secrets, trauma, murder mystery, and sisterly bonds into an addictive narrative.

The story follows Amanda, an adoptive daughter who receives a phone call that shakes her identity: a woman named Georgia, locked inside a psychiatric facility and accused of murder, claims to be her biological twin. When Amanda goes to visit her, Georgia insists she’s been falsely accused of murdering her adoptive sister, Annabelle, and that she needs help escaping the locked ward. With everything Amanda thought she knew suddenly shattered, she steps into the tangled world of family secrets, unreliable narrators, trauma, and betrayal!

The story is told through the dual perspectives of the twin sisters Amanda and Georgia. Amanda’s introspective, logical voice contrasted with Georgia’s chaotic mental state makes the alternating chapters feel like an emotional roller coaster. Pekkanen displays her signature writing style in this book—layered, compelling, and with relentless pacing! The chapters are short and engrossing, often ending on cliffhangers that make the novel truly binge-worthy. The major themes revolve around trauma, dysfunctional families, long-buried secrets, and mental health—all of which are seamlessly woven into the story. The book also explores the notion of genetic bonds versus emotional bonds and makes a compelling argument for both through the twins’ strong connection and the compelling bond between adoptive sisters Georgia and Annabelle.

Amanda is a rational and reliable protagonist. Once she meets Georgia and hears what she has to say about her alleged innocence and need for help, she mulls over the entire situation before planning her next steps. She then becomes an amateur sleuth, meticulously planning out each step in her investigation and the people she wants to interrogate. What’s most compelling is when she recognizes that the twin bond has always been there—this gives Georgia’s words further credibility and fuels a fire within her to save her sister. Amanda’s emotional arc, from initial detachment to full-on confrontation, is very compelling and pronounced by the end!

Georgia, on the other hand, is volatile and unstable—the epitome of an unreliable narrator! Her inner monologues are written with an erratic intensity that adds complexity and discomfort to the story—and will keep readers wondering if she’s ever really telling the whole truth! As her mind begins to unravel in the psychiatric ward, triggered by trauma, the deranged environment, and the looming threat of another volatile patient, Josh, her POV becomes increasingly unhinged. Her POV is sometimes written in 2nd person or in a fragmented way to fully immerse the reader into her unstable mindset! Georgia’s relationship with Annabelle and the details of her murder are presented through painful memories. Annabelle’s lingering presence is felt in Georgia’s inner monologues and during confrontational scenes with her stepmother, adding fuel to the family’s emotional conflict and mystery surrounding the murder!

The psychiatric hospital setting is one of the most unsettling elements of this book. Through Georgia’s disturbed lens, readers get a sense of its claustrophobic, clinical, and menacing atmosphere, and it creates a constant sense of unease whenever chapters are situated there. Every person that Georgia encounters there is either a threat or not to be trusted—most notably the volatile man Josh, who attempts to intimidate Georgia and attack her on a number of occasions. This book is a plot-driven thriller—the dual POVs, split timelines, and unreliable narrator will keep readers fully engaged the entire time. The first half builds slowly, creating a lot of unanswered questions and what appear to be plot holes. The pacing and tension skyrocket in the second half, and all the missing plot points are masterfully unveiled through clever twists, red herrings, and psychological turns! The final twist isn’t easy to predict and is emotionally compelling—but it may not fully satisfy seasoned thriller readers who are looking for something groundbreaking.

Overall, The Locked Ward is an addictive, emotionally resonant thriller with strong themes of identity, family secrets, and mental health. Georgia’s unraveling mind blurs the line between truth and delusion, making the story extremely unpredictable and compelling. Readers who enjoy locked-in thrillers, unique atmospheric settings, unreliable narrators, and lots of twists and family drama will love this book!
