I'm sorry to say this didn't work for me at all. It requires complete suspension of disbelief, and at that point, I have to wonder why the book is worth my time at all. I didn't like the main character, and her actions didn't make sense, so nothing was compelling there for me beyond the easy writing style. I don't get the point of the story and that makes it completely uninteresting to me.

I don't know--maybe it's just me. This is my second read by this author and, again, I find myself disappointed in a book that looked so good for me on its surface.

Other reviews have talked about the overall plot. I won't reiterate that here, but I will say that the increasingly implausible occurrences made it hard for me to fully buy in. Furthermore, while the subject matter is mostly quite adult-oriented, I felt too often like Thea, the protagonist, was a (very) young adult, at best. (The whole Stargirl thing was . . . . a lot.) As I pushed through to the conclusion, I did have some interest in seeing how the author would wrap the whole thing up, but beyond that, I didn't feel much of a connection to the characters or the storyline.

I am willing to say that the problems here might all be mine. Lots of folks are enjoying this one, so maybe give it a try. But if it doesn't work for you, just remember I told you so.

I thoroughly enjoyed Julia Bartz debut novel, “The Writing Retreat” so I went into this with the expectation that I would also really love this. Unfortunately, that was not the case. The book started off really well but as it went on, it felt like it was going in such a weird route as we hit different parts of the book. Random stuff felt like it was just getting added to the plot at times that made no sense for the book.
I liked Thea’s character, but felt like we could’ve gotten more, could’ve had more from her. Her character had power potential, but really it felt like 90% of the time she was so focused on the idea of “Stargirl” which felt wrong. Like at some point it was almost a full chapter of Stargirl this Stargirl that. Thea also has absolutely no survival instinct which drove me INSANE.
The mystery was interesting, cults are always an interesting topic when it comes to books because you can write them in so many ways.

I received a complimentary copy of this book through Atria Books/Emily Bestler Books via NetGalley. All opinions expressed in this review are completely my own.

I read 67% of this novel before my Kindle froze, and the document would not open when I refreshed my device. Since the novel already archived on NetGalley, I was unable to download the document again in order to finish it. That being said, I did not connect with any of the characters. The story quickly became strange after the first part, but I did want to finish it just to see how it all wrapped up.

I wish I could give feedback on this book. I requested this book when it was still possible to transfer on Kobo.

I'll update this review once I read this book on my own.

This book was not for me.
It was extremely sexual for a thriller. It was my first by Julia Bartz, and I don’t care for her writing style.
Wish this one could have been different.
Thanks netgalley for the arc!

Ok so first off, I have to say that the synopsis for this book makes it seem different than it really is. So here's my version: Woman who had a teenage parasocial obsession with an actress runs into that actress as an adult when that actress shows up as a patient in the psych ward where she works. When that actress leaves, woman drains her bank account to follow said actress across the country to a cult. Things get culty and the book gets weird.

I had really high hopes for this after absolutely loving The Writing Retreat. And the story was intriguing here, but the writing just did not measure up. The book felt repetitive in places, many of the characters were annoying, and the last 15% or so of the book just didn't make any sense. I also don't know how to put into words my feelings about Thea's big sexual secret. Or the fact that she is obsessed with sex in general throughout this book. Thea also simultaneously acts to smart and so stupid. She regularly questions Moon and Sol's methods and credibility, and pretty instantly is like "this place is kind of like a cult." But then it doesn't even phase her that the wifi is always out and keeps innocently asking about it. Like, hello, of course they're trying to cut off your contact with the outside world. That's what cults do.

Unfortunately, I was disappointed in this one. Thank you though to NetGalley and the publisher for an ARC!

Thanks for the ARC NetGalley! I loved Bartz’s “Writing Retreat,” which was an over the top thriller. This one was wild in a different way- it took me a bit to get into, but then I was sucked in. But the book is uneven in pacing and I was left with some questions.

Thea is a social worker who recognizes her traumatized patient Catherine from the beloved film Stargirl she was obsessed with as a girl. Catherine doesn’t remember much of the trauma that led her to Thea, when she’s suddenly removed from her care. Thea traces her to an isolated influencer cult in the desert where she joins undercover to help liberate Catherine. But Thea uncovers so many other despicable secrets disguised as wellness, she doesn’t know what to do.

The first third of the book I struggled with, but the creepy yet beautiful atmosphere Bartz crafted in the desert cult hooked me. I really didn’t know what would happen. The middle of the book was excellent but the end a bit rushed and over the top. I also could have done without all of the Stargirl lore peppered in (I felt this about Bartz’s debut which contained passages of a novel throughout that I didn’t need.) I will continue to read whatever Bartz writes, but this wasn’t quite the home run I wanted it to be.

The Last Session by Julia Bartz is about a social worker named Thea who confronts her past when a catatonic patient triggers memories of a traumatic event and then disappears. Determined to learn more from her patient who has conveniently disappeared, Thea makes her way to a very unconventional wellness center in the desert, At the wellness center, Thea uncovers disturbing secrets that were buried for a reason.

This book was a slow for me. I initially struggled to become fully engaged. I took me a . Having enjoyed the author's previous work, I was eager to jump into her new novel.

However, I found this book failing to captivate me and sometimes outlandish. The cult-like environment depicted was interesting and unexpected until it became a bit unrealistic.

If you are drawn to narratives featuring cult-like dynamics and personal traumas, this book might just hit the spot for you.

When a comatose, amnesiac, patient shows up at the psychiatric hospital where she works, Thea is certain she recognizes her. She discovers the woman is an actress, who starred in a film Thea was obsessed with as a teen. When the woman suddenly disappears from the hospital, Thea can’t shake the feeling that something is wrong, and follows her to a wellness retreat in New Mexico. What follows is a story of cults, murder, kidnapping and prophesies, as Thea learns more than she bargained for.

This book was unhinged in the BEST way possible! While it’s definitely a “trust the process” type of plot, it hooked me from the very start. I want to keep my review spoiler free, so I’ll just say that most of the characters are purposely unlovable. Their quirks get stranger and stranger as you go along, which adds to the twists and turns of the story. By the end, you’re not sure who, or what, to believe.

As long as you’re able to overlook the fact that Thea makes back-to-back-to-back bad decisions, I would highly recommend checking out The Last Session!

Read this if you're into locked-room mysteries, cult-y retreats, and twisty whodunits with a side of therapy talk

Another thriller from Andrea Bartz, and this one’s got all the ingredients for a page-turner: a remote wellness retreat, a group of people with secrets, and a decades-old mystery resurfacing. I was hooked from the start and really wanted to know what happened.

The setting was a standout—it’s easy to picture the isolated retreat with its tension-filled therapy sessions and cabin-in-the-woods vibes. The mystery itself kept me guessing, and Bartz definitely knows how to build suspense.

That said, the characters felt a bit too much like stock types: the guru, the skeptic, the damaged-but-deep one, etc. And sometimes their choices were baffling in a “no one would actually do that” kind of way. The story also tried to juggle a lot of themes—trauma, groupthink, influencer culture, recovery, secrets from the past—and it didn’t all land. It was like three different Big Ideas trying to fit in one book.

Still, I tore through it and was curious enough to see it through. If you like a moody mystery and don’t mind suspending disbelief for the sake of some drama, this could be a good weekend read.

Thank you NetGalley for the copy!

After Bartz’s first book (The Writing Retreat) I couldn’t wait to dive in to this one. It was everything I wanted and more.

The characters were captivating and infuriating. The story was mesmerizing and though bizarre, it was also realistic. As someone who lives in LA and has been lightly exposed to cults/cult-like behavior especially in the spiritual community… I was pretty impressed with how Bartz captured the essence of subtle manipulation among these types of groups. Watching the subtleties develop into extremes was beautifully and delicately done.

Color me enthralled and consumed.

Couldn’t put this down. Couldn’t stop thinking about Catherine and how trauma and patterns will dictate your life if you let them.

For those who may find this story/plot unrealistic or too over the top.. it may simply reflect experiences that are outside their personal frame of reference as i would have felt the same prior to my own experiences.

Also for those who watched Love Has Won: the cult of Mother God or Escaping Twin Flames ... this book is sure to take you on a similar ride.

Not as great as Bartz's last book - was expecting something totally different based on that and was unfortunately disappointed!

A catatonic woman is admitted to the psychiatric unit where Thea works as a social worker. Thea feels an unsettling familiarity but can’t place it. When the woman finally speaks, she claims to remember nothing. Then she vanishes.

Thea’s search leads her to a remote wellness retreat in the New Mexico desert—a place where guests surrender their autonomy to a magnetic couple promising healing through radical intimacy. The deeper Thea goes into the program, the more blurred the lines become between therapeutic recovery and psychological control. As she’s drawn into increasingly vulnerable exercises, Thea is forced to confront a past she thought she’d escaped—and a truth that may unravel her completely.

This is a taut, emotionally charged thriller that balances suspense with quiet psychological depth. Thea’s journey is both a gripping investigation and a raw excavation of personal trauma. The setting heightens the claustrophobia, isolation, and intensity of each interaction, as the story builds toward a deeply satisfying—and disturbing—conclusion.

Final Thought:
This is a haunting exploration of what it means to lose and reclaim control—in your mind, your body, and your story. Gripping, thoughtful, and uncomfortably real.

Thank you so much to the publisher for my ARC copy!

This book had me on the edge of my seat! A social worker, Thea, finds a catatonic celebrity in the public mental hospital she works in, and they eventually form a connection. When the celebrity checks out early and without warning, Thea feels like something is wrong. She finds out where she might be, and follows her out there, only to find a very creepy New Mexico wellness retreat -- with a darker side. This story definitely kept me on the edge of my seat with twists and turns. Thea's own beliefs are challenged as she gets sucked deeper and deeper into the mystery of what is truly going on at the retreat. The story is a little over the top at times, which I see in other comments too, but honestly, I enjoyed that about it.

This book pulled me in right away. The tension at the start was so good, especially when Thea starts trying to figure out the identity of a mysterious woman she comes across. That reveal really made me want to keep reading to see where things would go.

The setting really stood out too. The retreat in the middle of the New Mexico desert felt so off in a creepy, almost dystopian way. You could just feel that something wasn’t right, and that feeling hung over the whole story in the best way.

The pacing kept things moving, and I have to say, Thea’s little side quest felt totally chaotic but somehow worked. I also really liked how strange and unsettling the retreat leaders, Sol and Moon, were. Every time they showed up, you just knew something weird was about to happen.

If you like books that have an uneasy, mysterious vibe with characters you are constantly trying to figure out, this one is worth checking out.

Set against the backdrop of a final therapy session, the story unfolds as the protagonist confronts pivotal moments from her past, seeking closure and understanding. Bart's writing is lyrical and nuanced, capturing the raw emotions and vulnerabilities of her characters.

The interplay between the therapist and the patient reveals deep insights into human nature and the struggles we all face. With its rich character development and thought-provoking themes, The Last Session is a compelling exploration of relationships and the journey toward self-acceptance. Readers will find themselves reflecting on their own experiences, making this a relatable and impactful read.

When a mysterious patient appears at a psychiatric unit with no memory of how she got there, and disappears just as mysteriously, social worker Thea takes it upon herself to find the mystery patient. She feels a connection to this woman and a duty to follow the clues she left behind. The clues take Thea to an isolated wellness retreat where she is exposed to highly unethical methods and conditions, but doesn't feel able to leave until she finds her patient, and possibly learns more about herself and her own past trauma.

This locked-room thriller is full of suspense and unease. Thea doesn't know who she can trust and therefore neither does the reader, so everything and everyone becomes suspicious. This kept me guessing and was a wild ride.

I really enjoyed this in the beginning, and the. Things took a turn. I found so much of the MC’s actions to be unbelievable. The whole second half was just really out-there and not my cup of tea.

Initially, I had a hard time getting into this book, but the story definitely develops and becomes crazy, somewhat unbelievable if I'm honest. But I think that's the point!

Thea is a social worker working on a psychiatric unit when a familiar patient comes in. She is familiar, but she doesn't know why, but she is sure she knows her from somewhere. The patient is first unresponsive, no one knows why she is there. As she begins to come to, she claims she does not remember what happened to her or why she came to the unit. Thea shows up to work and finds that the patient was picked up by her parents. But Thea does not believe that. She reviews security footage and senses that something is off.
Thea is adamant about finding her. She finally does and finds herself at a retreat with some unusual hosts. The retreat specializes in help people uncover sexual issues/desires. To get answers, Thea joins the retreat and is forced to participate. But what she does not expect, is the participation helps provide answers to her past.
