A mother's worst fear, a killer on the loose, a darkness visible... A gripping page-turner for readers of Candice Fox and Karen Slaughter from an award-winning author
Sergeant 'Hex' Rexford is the detective who caught the infamous serial killer Dr. Witcherton. Now, with a series of gruesome murders unfolding inside Coast Sanctuary - a hospital for the criminally insane - Witcherton claims to know who's behind them. Hex takes the case, determined to uncover the truth, even as his own body is failing him.
Beth Thompson is desperate to keep her children safe. Her violent ex is stalking her, her son's behaviour is growing strange, and his beloved teddy bear, Theo, might be more than just a toy. When an elderly woman offers Beth a remote cottage, it feels like a chance to breathe - but safety is an illusion.
Meanwhile, true crime podcasters Eve and Zane are chasing the story of the murders. But as Eve edges closer to the truth, the danger closes in.
As past and present collide, and the body count rises, the threads connecting them all begin to tighten - and something terrifying is watching from the dark.
DS Hugh Rexford (‘Hex’) is the detective who caught infamous serial killer Dr Witcherton, a surgeon who carried out unethical brain surgery experiments on children he abducted. Now similar murders are being carried out inside a hospital for the criminally insane, Coast Sanctuary, where prisoners are being put through a rehabilitation program before being eligible for early release and Hex is convinced Witcherton knows who is responsible.
Podcaster Eve Harrington and her assistant Zane are investigating complaints made about Coast Sanctuary and the efficacy and safety of their early release program for dangerously insane criminals.
In a separate story line, Beth Thompson who works as an activities director at a retirement village, is struggling to separate from her abusive and threatening husband who has gambled his way through all their assets. At the same time, she is concerned about her young son Charlie and his struggles to cope with the separation from his father.
As all three story arcs start to merge, the creepiness and tension starts to ramp up, especially as the body count rises. The mix of police procedural, investigative journalism and domestic abuse all merges into a disturbingly dark and gripping tale that kept me engaged right to the twisted end.

This is an excellent story. I've read quite a few from this author now and rated them all high; this one is no exception, and may in fact be the best yet. A true page-turner from the very beginning, it features a dark storyline of murder, violence and the mentally ill. With alternating character perspectives, it initially seems like all of our main characters are dealing with separate problems but it becomes clear that they may in fact be connected in some way. This book is a really well-written novel with plenty of twists and turns that will keep readers engaged to the very last page. It's dark, it's creepy... it's a winner. Overall: highly recommend this book for those that enjoy crime thrillers, definitely a top read of the year for me.
⭐️5 Stars⭐️ Dark Sanctuary by Sarah Barrie blew me away, it’s dark, atmospheric and totally creepy, I don’t know if I could of read this one if I was home alone late at night, it’s the perfectly executed crime thriller and I highly recommend.
Detective Sergeant ‘Hex’ Redford is tasked with finding a serial killer with a link to the infamous serial killer Dr. Witcherton who is currently held in a facility for the criminally insane. Hex is about to retire and his body is letting him down.
Beth Thompson works at a retirement village and has become close to a woman called Rose. Beth is also being stalked by her estranged and psychotic husband and her young son Charlie who is five is showing signs of worrying and strange behaviour.
True Crime podcasters Eve and Zane are chasing up complaints around Coast Sanctuary, a hospital facility designed to rehabilitate mentally ill individuals from the criminal justice system.
Beth, Rose and Hex are my favourite and they’re all amazing characters. There are themes of violence, murder and coercive control that will make your blood boil.
There are many twists and turns and I especially loved the plot twist near the end, never saw that one coming. Sarah Barrie is an amazing writer, this is a book not to be missed!

I read this as part of the HQ Insiders team, thank you so much Harlequin Australia for a copy of the book.
A crime fiction tale, Dark Sanctuary (2026) by Sarah Barrie is a threefold narrative, murder mystery. Detective Sergeant 'Hex' Rexford was the detective responsible for capturing Dr Witcherton, an infamous serial killer. About to retire, Hex is asked to lead the investigation into the murder of Dr Dawelt, who worked at the Coast Sanctuary Mental Health facility. Beth is the activity co-ordinator at the local aged care village and is battling debt and separation, while trying to raise two children on her own. The third element of the murder mystery is Eve, who, with Zane, produces the Coastal Podcast, which is investigating local mental health services. These three threads alternate seamlessly into an enthralling read with a four star rating. As always, the opinions herein are totally my own, freely given and without any inducement.
What a heart stopping psychological thriller. I will never forget this story. Initially I was a little thrown but what seemed to be unconnected side stories but they coalesce in the most horrific and unexpected way.
As many deaths as a Shakespearean tragedy, and just as many difficult to read traumas (be warned - some of the most difficult psychological DV scenes I’ve ever read).
There's a plethora of 5 star reviews for this book but I'm afraid it wasn't for me.
I will admit that anything set in psychiatric hospitals annoys me. I just don't think these types of facilities still have creepy inmates carrying out experiments in the basements. In fact, I found the plot overall quite cliched and I had to suspend belief quite a bit. (At times I found Barrie's Lexi Winter series a little unbelievable, but this book was next level.)
The story was told from multiple points of view and a couple of those were pretty pointless. The leads piece everything together towards the end for no real reason instead of any type of investigation. Meanwhile, the murderer was obvious for the reader very early on.
Even though a lot seemed to be happening, nothing really happened and I found myself distracted and bored. I actually started this several times and gave up several times before I finally knuckled down and finished it.
I will still read Barrie's next book but I wouldn't recommend this one. 2 out of 5
This book doesn’t simply begin; it creeps into your peripheral vision like a shadow you swear wasn’t there a second ago, and before you know it, you’re knee‑deep in murder, madness, and the kind of dread that makes you want to turn on every light in the house. It’s atmospheric, it’s unsettling, and it wraps around you like cold fog that refuses to lift.
Sergeant Hex Rexford is exactly the kind of detective I fall ferally in love with — exhausted, haunted, stitched together with grit and stubbornness. He’s the man who caught Dr. Witcherton, the serial killer whose name alone feels like a curse. And now? Now he’s dragged back into the nightmare as bodies start piling up inside Coast Sanctuary, a hospital for the criminally insane. Hex is unraveling physically, mentally, emotionally — and yet he keeps going. Because of course he does. He’s that brand of broken hero who refuses to lie down even when the universe is actively kicking him.
Then there’s Beth Thompson — a mother in survival mode, clinging to her kids while her violent ex circles like a wolf. Her son’s behaviour is shifting, her nerves are frayed, and even the teddy bear feels wrong. When she’s offered a remote cottage, it feels like salvation… until you realise safety is just another illusion this book loves to rip away.
And floating above it all are Eve and Zane, true‑crime podcasters chasing the story like moths to a flame. Eve gets too close — because of course she does — and suddenly the danger isn’t theoretical anymore. It’s breathing down her neck.
The brilliance of this book is how all these threads — Hex’s failing body, Beth’s terror, the podcasters’ curiosity, Witcherton’s cryptic knowledge — start tightening around each other like a noose. Every chapter feels like a step deeper into a labyrinth where something is watching, waiting, calculating.
The atmosphere? Immaculate. Dark corridors. Unreliable shadows. A hospital full of monsters — some human, some not. A sense of dread that never lets up.
This is the kind of thriller that doesn’t just entertain you — it infects you. You read it with your shoulders up around your ears, muttering “oh no oh no oh no” while refusing to put it down.
By the end, you’re breathless, rattled, and absolutely convinced that something ancient and hungry is lurking just out of sight.
A masterclass in tension, character, and creeping horror. A 5‑star, sleep‑with-the-lights-on, “I will be thinking about this for days” experience.
4⭐️ - Another banger from HQ Books! This one follows multiple storylines that slowly come together as the story unfolds. You've got a detective investigating a disturbing case, a pair of true crime podcasters looking into a suspicious facility and Beth, who's desperately trying to escape an abusive relationship. I wasn't sure how everything was connected at first, but seeing all the pieces fall into place was so satisfying.
OMG, the tension in this! 😮💨 It gets pretty dark, especially with its themes of violence, trauma and coercive control. There were twists I never saw coming and every time I thought I'd figured things out, the story pulled the rug out from under me again.
Sarah Barrie's writing had me completely hooked from start to finish and that ending genuinely caught me off guard.
Thank you so much to HQ Books for the gifted copy!
A few storylines to follow and anticipate the moment the storylines begin to merge together. Some fabulous characters and satisfying moments of karma along the way. Thanks to HQ INSIDERS for the opportunity to read and review an ARC of this book. This was full of suspense and a must read for lovers of psychological thriller novels.
This book comes straight out of left field, slaps you and demands your attention….and it’s not going to take no for an answer.
I’m a massive fan of Sarah’s Lexi Winter series, Lexi is one of my all time favourite characters, so I was a little nervous on just how Sarah was going to move on from there. However, there is no doubt that she had done just that, and in true brilliance.
Dark Sanctuary is told from the point of view of the three main protagonists. Sergeant ‘Hex’ Rexford is a detective at the end of his career and possibly his own life, but with a determination to see a serial killer caught. Beth, a mum doing her best trying to survive her ex and keep a roof over the heads of her two children. Then there is Eve, a podcaster with a difference, she has her heart in the right place and is trying to find the truth.
There are a wide variety of characters in this story, and they all play their part impeccably. Some will find a place in your heart, and to put it bluntly, there are one or two that will rile you up and you will want to punch them in the face, but regardless, they will all bring your emotions front and centre as you make your way through this book.
This captivating story is entertaining, action-packed, emotional and full of twists and turns around every corner. It had my attention from the opening prologue, and didn’t let go until the very end, well to be honest, it didn’t let go even then as it has stayed with me while I write this review.
There is so much I’d love to say about this book, seriously I will be talking about it long into the future, but I don’t want to spoil anything for other readers, so I’ll leave it there and just say…..you really need to grab a copy of Dark Sanctuary and see for yourself….but maybe lock your doors if you’re reading it at night.
Thank you Harlequin Australia for my fabulous ARC in exchange for an honest review.
Dark Sanctuary is one of those books that creeped the heck out of me!! Well done, Sarah, for making me afraid of teddy bears for the foreseeable future.
In what seems to be three totally unrelated plotlines comes together in the most shocking way in this novel that looks at the mental health aspects of criminals. Can these people be rehabilitated... Or is the help available making their issues much worse?
Beth is a single mother of two who's trying to escape the clutches of her nasty ex-husband. When a friend offers Beth a secluded cabin to stay in, it should be a dream come true. Right?
Sergeant 'Hex' Rexford is the man who put the infamous 'Witch Doctor' behind bars many years ago. On the verge of retirement, Hex is brought back into the fray when a serial killer strikes. Because both sets of murders are eerily similar, it's safe to assume that The Witch Doctor knows who's behind these latest killings... Even orchestrating them. With Hex's health not the best, time is ticking for him to get results FAST.
Meanwhile, popular true crime podcasters Eve and Zane have caught wind of these murders. The story is too hot not to handle, but are they placing themselves in more danger the longer they investigate?
Returning to the Central Coast (where the incredible Lexi Winter series was set), Dark Sanctuary has everything I love in a gritty psychological thriller. Unlikable characters, a gritty narrative, plotlines that will shock and just for fun, boundaries pushed to the limit.
I'm calling it. Sarah Barrie is Australia's answer to Karin Slaughter, all thanks to this unputdownable read. Dark Sanctuary is honestly her best work to date.
A really good thriller! The plot is very interesting and keeps you guessing with lots of twists and turns. About gory in parts but definitely recommend if you love a good mystery/thriller.
This was a cheap thrills kind of book. I enjoyed the alternating POV's and generally liked most characters. I didn't have to concentrate or think too much reading it, I enjoyed the storyline, but I saw every twist coming, so I can't say I was too surprised by anything that happened.
After devouring and loving the Lexi Winters series, I have been looking forward to a new Sarah Barrie story.
And I was not disappointed.
we get 3 different story arcs and views of this story, however they all merge to give us a book that will keep you on the edge of your seat, needing to know what is going to happen next
It was a bit of a slow start for me, however as the story progresses, the creep factor and the thrills ramp up. I was left holding my breath as I turned each page.
I also like that I know a lot of the areas that Barrie writes about in her stories, which gives a bit more oomph and realism for me.
Now I am wondering what she can do to enthrall me next.
WOW! What an absolutely fantastic thriller. I absolutely LOVED it. Dark Sanctuary was full of suspense, mystery, murder, secrets, and killer twists that I didn't see coming.
I was completely blown away by how good this book was. Sarah Barrie has been a go-to thriller author for me for a while now, especially since her Lexi Winter series, but she's taken it to another level with Dark Sanctuary. It was very well written. It was dark, emotional, twisted and down right addictive. I couldn't put it down.
I love that it was told from three very different point of views. I enjoyed reading about each of them: Hex: police officer, Eve: podcast journalist, and Beth: Single mother, leaving an abusive marriage. I especially loved Beth. She was brave, strong, smart, and determined. Sarah wove these stories together beautifully, with a few epic twists along the way. I can't wait to see what she comes up with next.
I very highly recommend. This is honestly one of the best thrillers I've read in years.
5 stars from me. ⭐️⭐️⭐️⭐️⭐️
For fans of Sam Holland, J.D. Barker, Sharon Bolton, and M.W. Craven.
Thanks to Netgalley, Harlequin Australia, and Sarah Barrie.
Gruesome murders, a serial killer, a hospital for the criminally insane, a podcast, creepy teddy bears...caught your attention? It should have! And you absolutely need to add this book to your TBR if you like dark, gritty murder mysteries. Sarah Barrie is the Queen of Aussie Crime.
Now, there are a lot of characters in this book so I will admit it took a couple of chapters to really settle in to the flow of the story. But before I knew it I was hooked. I loved the slow reveal of how the character's stories were going to intersect. The story was downright creepy in parts and I was seriously questioning my decision to read it at night after everyone had gone to bed 😅 but I also couldn't possibly put it down. Creepy, clever and addictive. Love love loved it!
WOW… this one is going to live rent free in my head for a while!
This one is dark, twisty and completely gripping from start to finish. The atmosphere is seriously unsettling (in the best way) and I found myself hooked on every layer of the story as it unfolded.
The multiple POVs worked so well, slowly building the bigger picture, and those twists?! I genuinely didn’t see some of them coming.
It definitely feels like her darkest book yet, with that perfect mix of psychological edge and creeping unease that keeps you turning the pages late into the night.
Dark Sanctuary was an addictive read, emotional, gripping with just the right amount of creeping unease.
If you love thrillers that keep you guessing and give you goosebumps along the way… add this to your TBR immediately.
My head is still spinning from this epic psychological thriller
Strap in, it’s an intense and dark ride!
With two stories running concurrently, we see Beth desperately trying to escape the clutches of her horrible and controlling husband Byron. Now living in a less than ideal rental, trying to shield her children from his reaches.
Sergeant ‘Hex’ Rexford is the famous detective who many years ago put serial killer Dr Witcherton behind bars. But now as gruesome murders are being discovered at Coast Sanctuary (a hospital for the criminally insane) Dr Witcherton claims to know who the killer is. The causes Hex to take the case, with podcasters Eve & Zane eager to solve the crimes
As the story flows the tension builds with short chapters and past and present POVs
Dark, creepy, at times very very frightening (Beth & Byron’s encounters were intense and horribly unsettling) the glimmers of hope kept me going
While there was a lot going on, I was desperately trying to piece together the clues and shocked to my core with the final reveal - DID NOT SEE IT COMING!!
I have Sarah’s Lexi Winter series on my TBR and I will absolutely be bumping it up!
Dark Sanctuary is a must read thriller - highly recommend
Thank you HQ Books for sending me this as part of the #thrillerbotm - the perfect Thriller book!
I was hooked from the very first page as Dark Sanctuary wove its tendrils into my page turning finger. This book has everything I love and I was instantly addicted. Unlikable characters, podcasts, plot twists and much much more which just cemented the fact that I will read what everything Sarah Barrie writes.
Dark Sanctuary follows three main characters, Hex, Beth and Eve, I knew their stories would intertwine at some stage but I was surprised at the depth their journeys took and was wowed with their eventual collisions. There are a lot of surprises in this book, one that left my jaw on the floor, and kept me reading at warp speed to the final conclusion.
I highly recommend Dark Sanctuary to all thriller lovers, it is a fast paced, unhinged and at times very dark read, it will get your blood pumping and keep you reading long into the night. Thank you to NetGalley and Harlequin Australia for this early reading copy, five big stars!
We follow three main character, Hex - a detective, Beth - a mother going through some struggles, and Eve - a true crime podcaster.
Sarah Barrie captured my attention instantly with this book; it held me from the very get-go. The perfect read for any thriller/crime fans out there. Being set local to me on the Central Coast; I also found it even more gripping to read.
Definitely one for the thriller fans to add to their TBR’s, the plot twists were fantastic!!
Thank you to HQ Insiders for giving me the opportunity to ARC read this story!
A brilliant page turner. Full of suspense, surprises & intrigue. Would have liked to learn a bit more about what happened to Hex’s team afterwards, but maybe it could lead to another book? Hope so. Thoroughly enjoyed this book.
I’m a huge fan of the Lexi Winter series, so I was excited to read Sarah Barrie’s newest crime novel, Dark Sanctuary.
This thriller is written in many different perspectives; throughout most of the story there are three. Therefore, from the beginning it is clear that these lives and stories will be connected, and throughout the story as a reader you strive to piece it all together. For this story, I feel that format didn’t quite do the storylines justice. It made certain characters easier to pinpoint as ‘suspicious’, and I think overall reduced the shock-value of the twists and turns.
I received a copy of Dark Sanctuary as an advanced reader copy, and there were some formatting issues with the digital ARC. I am unsure if this is related to that - but there were some grammar issues throughout some of the conversations. Some dialogue was written a bit clunky – it made me re-read sentences to confirm meaning. This stood out to me as I am familiar with Barrie’s work, it seemed unusual and disjointed.
In addition to this, I found the start of the book quite slow. I feel that it relied on the ‘shocking’ nature of the murders that were committed to keep the reader engaged, missing Barrie’s typical ‘punchy’ storylines and movement of stories. The storyline involving domestic violence in one point of view felt both rushed and shallow, and often unbelievable, while throughout most of the story the point of view of the podcaster (Eve) felt unnecessary. Perhaps this is an unpopular opinion, but I feel that Eve’s storyline could have been told through the storyline of the head detective Hex, rather than given its own point of view. The POV felt lacking and only present to further a particular twist and turn.
Towards the end of the story (about 70%) however, I felt Barrie’s magic start to trickle in. She truly thrives in action packed, fast moving and shocking scenes, and this was clear throughout the Lexi Winters series. The twists and turns felt realistic and probable, and kept me hooked and engaged up until the end of the story. The end was satisfying, clear, and impactful, and it did leave me wanting more – which is an excellent way to conclude a book.
I rated this book as a whole at 3.5 stars. I would rate the first 70% 2.5 stars, and the final 30% 4 stars. Overall I greatly enjoy Barrie’s writing style, I just found the start of the novel to be a bit lacklustre.
Thank you so much to HQ Books Australia for providing me with an advanced copy of this book for me to provide a review with my complete and honest opinion.
Beth Thompson, a young mother who is trying to free herself from her manipulative husband and who in turn tries to use their children to get his way.
Rose, an elderly woman who wants to help Beth but also her own demons to battle.
Eve, a crime podcaster trying to chase a story for the next episode.
Sergent Hex Rexford, who is close to retirement but is desperate to solve the case of a serial killer as he has carried some guilt over the investigations when all started many years ago.
This is a very unsettling story. At times I saw or guessed how paths might be connected and this added to the feeling of unease. It made me get up to make sure the doors were locked.
And it will take some time until I can pick up my knitting needles and not think of this story….
Thank you Harlequin Australia for sending me an Advanced Readers Copy as part of the HQ Insiders program.
I've read and enjoyed all of Sarah Barrie's books so far, I really liked the Lexi Winter series. I was very excited to receive this book from HQ Insiders to read and review. There seemed like a lot of characters in this book at first, and two very separate story lines. But eventually the two story lines cross over with a bang.
I read this book in less then 24 hours and that was on a work day! I had to keep reading to find out what happened. I thought I had an idea but there were still some twists and turns to come.
I enjoyed the setting, some places that I had been to before. I do enjoy novels using real locations.
I think readers of Candice Fox would enjoy Dark Sanctuary.
This was a very fast paced thriller with lots of characters.
This ARC did have some typos, a name mix up 3 times in one page and 2 major story line errors. Hopefully those will be picked up by editors before the final edition is released.
OMG! This was absolutely amazing! So many thoughts running through my head! I could not put it down!! WOW! Truly a twisted Thrill! So many great characters, this story was Woven to perfection!!!
