Beloved #1 bestselling author James Patterson delivers a thrilling novel about a teen caught between two worlds and the truths that could set her free—or trap her forever.

My name is Hannah Dory and I need you to believe me

NOW: Hannah Doe is brought to Belman Psych, kicking and screaming, told she is suffering from hallucinations and delusions.

1347: Hannah Dory and her village are starving to death in a brutal winter. Hannah seeks out food and salvation in the baron's castle. If she is caught stealing, she will surely hang.

NOW: Hannah knows the truth: she is Hannah Doe and Hannah Dory, and she must return to the past before it's too late to save her sister. Can Jordan, the Abnormal-Psych student who seems to truly care, be the one to finally help her?

Jordan isn't sure what to believe, and Hannah has even bigger problems: if she doesn't make it back, her sister will die, but if she keeps going back, she might never escape.

This was a very suspenseful book. The story lent itself to both contemporary fiction or possibly Scifi/Fantasy and for the majority of the book I wasn’t sure which genre the story would be. On the one hand, the book could be a contemporary fiction about Hannah Doe, who is suffering from a mental illness loosely diagnosed as Schizophrenia. In that version of the book when we get to the segments on her life as a peasant in England in the 1300s, that is her mind’s protection mechanism to escape trauma with which she isn’t ready to cope. However, since this is a novel, I did wonder if it was going to end up as Sci-fi/fantasy where she really was time traveling and no one believed her. The fact that her life in the 1300s was well fleshed out compared to her gray existence in modern times where she is barely holding on to her sanity definitely made it seem possible. Either direction the story took would have been an interesting read and it went back and forth on which theory would win for a while making it impossible to stop reading.

The story is sometimes told from Jordan’s perspective. He is a young intern trying to learn more about mental illness before he enters medical school. He is young and idealistic and thinks that he especially can help Hannah even though she has been in and out of Belman since she was young and the staff knows virtually nothing about her past. The description of him resonated with me because he isn’t jaded by the system and college students often seem ready to tackle all the world’s problems and make a difference. His character’s decisions raise some ethical and moral concerns. His intentions start out wonderful. Hannah is charismatic and a fascinating subject for someone trying to understand mental illness. He takes time to listen to her and takes a special protective interest in her. When Hannah is in the present, she is lucid and so normal that he can’t quite get over that she is fighting mental illness and isn’t just a girl about his age. They both fight the urge to get closer and his presence is a catalyst for her desire to leave the castle for good as well as a bomb waiting to go off on her stability. His passion to fight for her recovery leads him to dig up her past and finally answer the question of what is going on with her. This is arguably a good thing but leads him to many regrets over his actions and the real-life consequences for Hannah’s health.

The ending was a bit rushed after we became invested in uncovering the truth. For those who love potentially happy endings that wrap up neatly this is a good book to choose. Jordan’s character gave statistics throughout on the frequency of mental illness in the population and how few people get adequate treatment. The other patients are suffering and sometimes losing their battle with mental illness. I am not sure if this is a book that would resonate and empower others suffering with their mental health to seek help or if it could potentially make their own personal fights worse. I guess my best advice is to say to tread lightly with this book if reading about mental illness could destabilize your own well-being. As a book, it was fast-paced, intense, and suspenseful making it the perfect read for someone wanting to get sucked into a great story.

THE GIRL IN THE CASTLE is an intriguing suspense read that follows Hannah and Jordan. The reader first meets Hannah while she is having a breakdown in a store, accosted by the police, and then taken to a mental institution. She has been in and out of there for years, and they do not really know how to treat her. She has some features of schizophrenia but does not quite look like the textbook. Hannah experiences a life in the 1300s where she was a peasant, and she frequently escapes there mentally.

Jordan is a college student who wants to learn more about mental health facilities. On his first day of shadowing, Hannah is brought in, and he feels a connection with her, wanting to help her. As he talks with her, he begins to consider what could have caused the psychosis and how it might be treated.

What I loved: The story was intriguing with the 2 timelines, primarily the historical timeline seems to be stronger as Hannah is living a full life surrounded by death there. The timelines are interspersed with documents from the mental health facility and police, primarily regarding Hannah, but sometimes about other residents as well. It certainly created an intriguing mystery that readers will be eager to see played out.

What left me wanting more: I struggle with the representation of mental illness here, as the therapeutic approach versus Jordan's were a bit of a mess. Other residents seemed superfluous and it was tough to get to know and care about them. I think it could have been a stronger story if we had focused more on the present Hannah and her time in the institution as well as seen some of the benefits (maybe for other residents) of treatment. The resolution provided at the end did not feel like enough given all the build up, in terms of how the timeline skips at the end (being vague so as not to give spoilers). I also struggled with some of the personality flips/rapid changes and evolving power dynamics, though I suppose this was also representative of the way things begin to unravel.

Final verdict: Overall, THE GIRL IN THE CASTLE is an intriguing suspense read, but I would have liked a stronger impact of the mental illness themes and a more focused story overall.

The Girl in the Castle is one of those stories that really pulls you in with its mystery and keeps you questioning what’s real the entire time.

The book follows Hannah, who is living in two timelines at once, one in the present where she’s placed in a psychiatric facility, and one in the past where she’s struggling to survive during a harsh winter. The way the story switches between these two worlds creates a lot of tension, because you’re constantly trying to figure out if she’s telling the truth or if everything is in her head. It makes the reading experience feel a little unsettling, but in a good way.

As someone who generally likes mysteries, I really enjoyed how this book keeps you guessing. It’s not just about solving one clear problem, it’s about piecing together what’s actually happening to Hannah. I liked how the story slowly gives you bits of information instead of explaining everything right away. My favorite parts were the scenes set in the past, especially when Hannah is sneaking around the castle trying to survive. Those moments felt intense and real, and they made the stakes feel higher compared to the present timeline. At the same time, the scenes in the facility added a different kind of tension, since you’re not sure who to trust.

One thing I will say is that the story can get a little confusing at times because of the constant switching between timelines. There were moments where I had to pause and really think about what was happening. But honestly, that confusion kind of adds to the mystery, since it puts you in Hannah’s position of not fully understanding what’s going on. I also liked Jordan’s character, because he brings a bit of stability to the story and gives readers someone to hold onto when things feel uncertain.

Overall, this is a fast-paced and intriguing read, especially if you enjoy stories that mix history with psychological mystery. My favorite part was trying to figure out the truth behind Hannah’s situation while watching everything slowly unfold. It’s the kind of book that keeps your mind active and makes you want to keep reading just to understand what’s really going on.

This was a fantastic read! Once I started I couldn't put it down and was done by the end of the day! There's a great mix of genres! Mystery, fantasy, ya and romance! It has some great twists! You really don't know what's fact or fiction so the guessing and the mystery just adds to the whole story! It's a fantastic story and Hannah is a great character with such an interesting life!
