The Twin Sister

Rate this book
I took my twin sister’s life. By life, I mean I replaced her. Is my new baby worth the price?

I’m Beth. Or I was, until the crash.

I’m a woman clinging to the frayed edges of a failing marriage. We’ve been trying for a baby for ten years now, and the strain of it all is destroying us.

My twin sister Cate has everything I’ve ever wanted — three perfect children, an adoring husband, a beautiful home.

The world revolves around her. I’m the paler, watered-down version.

Then comes the accident. A twisted wreck on the motorway. A single, devastating moment.

And a choice.

They thought I was my twin sister. And I didn’t correct them.

Now I’m living her life. Sleeping in her bed. Raising her child . . . But someone knows what I’ve done.

I thoroughly enjoyed this book! I'm an identical twin myself so will always read a twin trope thriller. This one did not disappoint.

After a tragedy, Beth takes over Cath's life, looking after her young baby. But someone knows her secret.

Oh wow. The twists and turns in this were so good! I was captivated and although Beth made a few bad decisions, I rooted for her throughout. The ending was perfect.

A wonderfully addictive twin thriller that blurs the line between truth and lies.

4 stars for me.

Beth,after the accident take her identical twin sister Cate life. After years of trying for a baby now she have the chance be a mother to her nephew Ted. It's not like her husband miss her,starting straight away living with his mistress after her supposed death.The only thing stopping Beth to finally live a life as a mother it's Cate secrets, and a dangerous man her sister seem to be involved with.

Will Beth get a life she dream of?
Will someone discover her lies?

This book was great.I could not put it down,the mystery, the tension and the story of Beth and Cate as children was executed flawlessly. Twists and unexpected alliances made it an interesting and different read. My first book by this author and hope to read more.

I would recommend this book for a thriller with an unexpected twists fans.

Thank you Joffe Books publisher for arc,my review is honest and my own.

I was eager to get stuck into this one because the premise sounded fantastic. I can now safely say this was a wild read! There was so much going on from start to finish, with twists and turns around every corner. It took a moment once I’d finished as my head had a lot to get around.

For me, I couldn’t really connect with the characters, they all managed to baffle me in their individual ways with their actions and as for Kate, I found it a madness that although she’d gotten herself into something big, it didn’t feel like the grief was really there.

This is one of those books that will have you feeling many emotions, you really become invested in the storyline and caught up in the chaos of it all. I don’t think I’ve read a thriller quite like this one, the author definitely made an impression on me.

This was entertaining.

I will warn you that there are a couple of graphic scenes involving that were a touch too much for me. There's also a touch of , so fair warning.

While I didn't love our MC at first, she eventually grew on me. I did love one character I fully expected to hate.

The story is very intense and suspenseful - you kind of much your popcorn while also occasionally biting your nails!

And I was happy to see that it ended very well!

All in all, a good read.

I devoured Yvette Davies debut novel—I couldn’t put it down! It’s devilishly deceitful, deliciously dramatic, and dove deep into sisterhood, secrets, and simmering suspense.

Beth’s life was falling apart, so when she got the chance to step into her twin’s shoes, she took it… but it wasn’t as perfect as it looked.

I loved the whole mistaken-identity premise — it’s eerie, original, and immediately grabbed my attention. The tension of Beth stepping into Cate’s life had that addictive “what would you do?” quality that kept me turning pages. Yvette Davies also did a great job capturing the messy bond between sisters, the envy, guilt, and complicated love that made the story feel believable beneath all the twists.

My only hang-up was that a few parts of the story stretched believability, but aside from that, I was utterly hooked.

In the end, The Twin Sister delivered exactly the kind of psychological suspense I love—flawed characters, buried family secrets, and enough tension to keep me flipping the pages quickly. I’ll gladly recommend this standout debut and can’t wait to read more from Yvette Davies!

Thank you Net Galley and Joffe Books for this advance copy in exchange for my review.

Wow! What a truly outstanding debut novel from Yvette Davies!
The Twin Sister is a relentless and dark psychological thriller that twists sibling rivalry into something truly macabre.
We meet unhappy, childless Beth, who seizes a chance to steal her twin sister's luxurious life and child. Although she initially believes her problems are solved, she soon enters a spiral of paranoia and guilt, constantly looking over her shoulder.
The novel excels in its raw portrayal of complex emotions. I was rooting for Beth as she attempted the near impossible feat of becoming the woman she always envied.
The tension ramps up with each chapter, and I was devouring every page into the wee small hours as more dark twists and potential disasters threatened Beth's new life.
The ending was crafted as neatly as a newly landscaped garden, cementing this author as a major new voice. I can't wait for the next book!

Have you ever looked at someone's life from the outside and thought they had it all together? Yvette Davies's psychological thriller The Twin Sister explores this dangerous assumption through a twisted tale of identity, envy, and the lies we tell ourselves about what we truly want.

Beth has spent her entire life living in her identical twin Cate's shadow. While Cate enjoys the picture-perfect existence—sprawling house, doting husband, three beautiful children—Beth struggles with failed IVF treatments and a crumbling marriage to a cheating husband. The contrast between their lives couldn't be starker, and the resentment festers.

Then tragedy strikes during what should have been a simple family outing. When the family splits into two cars—Cate with her husband and two children in one, Beth with the baby in another—a devastating crash changes everything. Cate's vehicle becomes a tomb for everyone inside, while Beth and the infant emerge as the sole survivors. In the chaos and confusion, authorities mistakenly identify Beth as the deceased twin.

And here's where Yvette Davies hooks you: rather than correct this fatal error, Beth sees an opportunity she's dreamed of her entire life. She becomes Cate, stepping seamlessly into her sister's designer shoes and taking on motherhood to the surviving child.

What follows is the exploration of the grass-is-always-greener mentality. Beth quickly discovers that Cate's "perfect" life was merely a glossy facade. The cracks begin to show, secrets emerge, and Beth realizes she's inherited far more than she bargained for. Meanwhile, her own husband David wastes no time moving his mistress into their former home, adding salt to already raw wounds.

The author weaves together two of thriller fiction's most compelling tropes—identical siblings and mistaken identity—creating a page-turner that kept me reading well past midnight.

The Twin Sister is a gripping thriller that reminds us to be careful what we wish for—and that sometimes, the life we envy might be the last thing we actually want.

Scrumptiously Disturbing & Utterly Gripping: The Twin Sister by Yvette Davies is a scrumptiously disturbing thriller that hooked me from the very first page. The story begins with a crash and quickly spirals into a life-altering deception. Beth, mistaken for her incredible twin Cate, makes a split-second decision not to correct the error—and in that instant, she steps into a life that was never hers.

What follows is a taut spiral of secrets, guilt, and surprises. I loved the stark contrast between Beth’s modest, ordinary life and Cate’s seemingly perfect world—until Beth discovers that perfection was just an illusion. Cate’s life was riddled with secrets, and Beth soon realizes she never really knew her sister at all.

The pacing is fantastic: short, concise chapters keep the action moving, and there’s never a lull. The twists kept me second-guessing right up until the final chapters, and the “story within a story” structure was cleverly crafted. I was especially drawn into Beth’s emotional journey as she becomes a mother to Cate’s surviving child—a role she longed for but never thought possible.

This is psychological suspense done right: a compelling premise, expertly written prose, and a constant sense of unease throughout. Things are never quite what they seem, and that’s what makes this book so addictive. Highly recommended if you enjoy fast-paced, twisty thrillers with emotional depth. I couldn’t put it down!

Thank you to the author, NetGalley and the publisher for an advance copy of this book for review consideration. I am voluntarily leaving this review which is my honest, unbiased opinion.

Most have us have wondered what it’d be like to switch places with someone, whether it be a stranger, or someone we know well. Most of us aren’t crazy enough to actually do so. Except Beth. Beths sister Cate has everything Beth has dreamt of – the perfect home, husband and children, until a fateful car crash allows Beth to swap places with Cate.
Beth is now living her life as Cate, with Cates baby Ted. How long until her lies catch up with her?

Actually gobsmacked this is Yvette’s debut!
I absolutely FLEW through this, it was so engaging and absorbing. The writing leaves you wanting more, but I also didn’t realise how quickly I was getting through it. I was completely drawn in by both Beth and Cate, and couldn’t decide who was worse. I definitely wouldn’t want a sister like either of them. A lot of times I genuinely gasped, one being very early on when Beth was snooping in bins.
There were some trigger warnings which were displayed at the beginning of the book (always appreciate this). Don’t get me wrong, some bits were quite unbelievable, however, it never got ridiculous and was just overall a great, fast paced, twisty thriller!
There wasn’t a huge twist at the end, everything just flowed naturally and ended neatly.
Thank you so much to Zooloo and Joffeebooks for the advance copy

Yvette Davies delivers a deliciously unsettling thriller in The Twin Sister—a story that begins with a crash and spirals into a life-altering deception. It’s the kind of premise that hooks you instantly: Beth, mistaken for her dazzling twin Cate, chooses not to correct the error. And just like that, she steps into a life that was never hers.

What follows is a slow-burn descent into secrets, guilt, and the creeping dread that someone knows the truth. Davies writes with a confident, cinematic touch—balancing domestic drama with psychological suspense. The tension builds not through gore or shock, but through the quiet unraveling of identity and trust.

Beth’s voice is raw and relatable, her longing palpable. The contrast between her modest life and Cate’s seemingly perfect world adds emotional weight, especially as cracks begin to show. And the final twist? It’s a shiver-down-the-spine moment that lingers.

Perfect for fans of Lisa Jewell and Louise Candlish, this is a gripping, emotionally charged read that asks: how far would you go to live someone else’s life?

Thanks to Yvette Davies, the publisher and NetGalley for the ARC.

Beth has an opportunity to get everything she has ever wanted a child of her own. In order to have this child, though she has to become someone else, her twin sister Cate. After her twin sister Cate, her sister's husband and 2 children are pronounced dead at the scene. She makes the decision to become her sister. In order to become the mother to her sisters one remaining child Ted. The only thing she didn't bank on was her twin sister's life being far from perfect. This book was not what I was expecting. It was so much better. Someone knows Beth's secret. Someone dangerous. Someone who will do anything to get what they want no matter the cost. The way Beth had to deal with this makes this the perfect drama and the perfect thriller. The character of Beth is so multi layered which really added to the storyline. I had mixed emotions about this character but I couldn't help but root for her. The dynamics between the twins is also fascinating. Some characters you cannot help but despise. I was so impressed with this book and would highly recommend this. A sinister tale with a spectacular finish will not leave you feeling disappointed!

This was my first read by this author and I later found out that it's actually a debut novel.

I was instantly drawn to it by the front cover image and my intrigued about what had happened to the baby!

 

This was such a great read and it really got me thinking about twins and how many times identical twins have switched places from small things - or something much bigger like this!?

 

This story takes the concept that the grass is greener and shows us the consequences - and as we know, it never turns out quite as we expect it to.

 

As the story unfolds, we find that Cate had her own issues and maybe someone knows what Beth has done.

 

This was really well written and kept me engrossed from start to finish.

 

The characters were really well presented and developed, especially the twins.

I liked seeing the flashbacks of their childhood and how this age ted the way each grew up and the dynamics between the families.

 

This was a great tense and twisty read that I couldn't put down - I can't wait to see more from this author as they develop even further - but what a great first book.

3.75–4 ⭐️

First, huge thanks to NetGalley and Joffe Books for the ARC!

I think this was a strong debut and an intriguing story that kept me on my toes. Every few chapters I found myself thinking, "Wait… are they gonna find out? Still no?!"

The idea felt fresh: two sisters, one tragedy, one identity stolen. Beth, our mc, steps into her twin sister Cate’s life after a devastating accident, and the further she sinks into the lie, the darker everything gets. But of course, Cate’s “perfect” life turns out to be anything but. Abuse (SA- so TW), control, manipulation, trauma ... the layers unfold slowly and the tone gets progressively darker in a way that really worked.

Beth as a character was fascinating to watch spiral. Sometimes I wondered if she was just unhinged or just a tiny lil bit morally grey. I didn’t always buy how easily she pulled off pretending to be her twin (it felt a little too easy/hard to believe it at times) but I got over it.

All in all, The Twin Sister is a twisted, emotional read about envy, identity and how far someone can go when they’ve lost everything.

For a debut publication that packs a punch this one by Yvette Davies delivers in spades.
A psychological thriller that you can't put down.

The story unfolds to reveal her sister too had a secret and its come back to ruin all Beth/Cate' s plans. Will she be able to continue with her new life or is she in danger of losing it
Twin sister is one of the best psychological thrillers I've read. It keeps you up at night until the spectacular end Yvette has devised.

This book had me completely hooked from the first chapter. It’s a dark, emotional thriller that dives deep into the complicated bond between sisters. The story follows Beth, who’s struggling with infertility and a broken marriage. When a tragic accident leaves her twin sister Cate and most of her family dead, Beth is mistaken for Cate and instead of correcting the mistake, she steps into her sister’s life.

I found the whole idea so gripping. Beth becomes a mother to Cate’s surviving child, something she’s always wanted, and suddenly she’s living the life she used to envy. But it doesn’t take long for things to unravel. Secrets start surfacing, and Beth realizes that Cate’s perfect world wasn’t so perfect after all.

The tension builds with every chapter, and I couldn’t stop reading. I loved how the story explored guilt, identity, and the idea of wanting what someone else has.

Beth is a flawed character, but that made her feel real. I didn’t always agree with her choices, but I understood her pain and desperation. The twists were clever.

I have to say, I absolutely loved this book and read it within 24 hours. It’s such a different type of crime book in that all the people involved write their own part of the story in the first person.

It’s starts off morbidly with a car crash and two women, who are in fact identical twin sisters are involved in the crash. However, Cate dies and Beth survives. Cate had everything, including a young baby, and Beth who couldn’t have children sees her chance to adopt Cate’s persona, and have the thing she wants most, her own baby.

As they are identical twins no one at first seems to question it, but for how long? Will she succeed and have her sister’s life and bring the child up as her own - you’ll have to read it to find out.

I thought the ending was brilliant and I’m not going to spoil it, but it was a gripping story and very well written. I thoroughly enjoyed it.

My thanks to the author, and Joffe publishers for the ARC.

The Twin Sister definitely puts the pscho in psychological thriller! Yvette Davies created a story within a story in this cleverly crafted suspense book. There was never a lull in the action as the two stories play out separately before flawlessly merging together.

Identical twin sisters Beth and Cate are at the center of this narrative. When Cate is killed along with most of her family, Beth slides seamlessly, or so she thinks, into Cate's life and becomes a mummy to Cate's surviving child, a role she longed for for years. All falls perfectly into place until someone discovers her truth.

This story was so expertly written and flowed smoothly. The chapters were short and concise and alternated perspectives. The premise of this story had me intrigued and did not disappoint. I highly recommend it.

Wow! I didn't see that coming. A real page turner of a thriller.

Identical twin sisters Beth and Cate. Cate has everything, a rich husband, a millionaires lifestyle, and three children. Beth has a more modest life but craves for a child of her own. Her marriage is suffering because her constant demands for a child and her husband David finally puts his foot down and refuse any more IVF treatment. Beth suspects that David is having an affair and storms off to a prearranged weekend in a holiday village with her sister and brother-in-law and her niece and nephews, whom she adores. On the way home, a chain of events brings Beth all she dreamed off and a whole heap of problems to go with it. Be careful what you wish for is the lesson!
This is a well written thriller with plenty of twisty turns to keep you hooked.

This book is an excellent thriller - original ad twisty in all he right places.

It comes with a trigger warning relating to sexual violence and this is one theme of the novel, but there are many other themes and a really well told story.

It starts with 2 twins approaching their 40s, rich Cate, who has married into money and had 3 children, and Beth, married and desperate to conceive but experiencing unexplained infertility and unsuccessful IVF. A tragic accident occurs and in a moment of madness Beth takes over her twins life! First thoughts are can she pull this off?! It soon becomes clear however that Cate's life is darker than Beth could have imagined.

Loved this novel and recommend it highly. My thanks to NetGalley, author and publisher for the opportunity to review this book in exchange for an advance copy.

Brilliant debut novel by Yvette Davies.
It really made me wonder — is the grass ever truly greener? Perhaps it is, but this story beautifully explores what we stand to lose as well as what we might gain when we go looking for it.

Very well written, full of twists, shocks, and surprises that kept me hooked from start to finish. I even found myself waking up thinking about the characters! I loved getting to know and understand them all (except for one I’d definitely rather not meet in real life!)

It’s a story woven with lies, deceit, love in many forms, and some unexpected friendships. It also left me wondering what it would be like to have a twin sister - though after reading this, I think I’m quite content not to!

A fantastic read that I could easily imagine being made into a TV drama. I can’t wait to see what Yvette Davies writes next!

Beth and David have been trying for a baby for a long time, but to no avail. Beth has noticed that David is distant, not showing any interest in trying to have a baby with her.

Beth’s identical twin, Cait, has everything Beth would want. Three adorable children, a beautiful home and not a thing to worry about.

Following the most awful tragedy, Beth steps into Cait’s life … but just how far can she go?

I enjoyed this book, it kept me entertained and wanting more. I liked how the author engaged with parts of Beth and Cait’s childhood, and showed just how they weren’t identical on everything - they were their own unique selves.

It was interesting to see how Beth assumed that Cait led a perfect life, completely different to her own.

I was not expecting the ending at all, but it was a perfect ending for this story.

I received a copy of this book from the publisher.

Beth has unsuccessfully been trying to fall pregnant for a decade. Her identical twin sister, however, has three children.
They all go away for a weekend together, leaving Beth's husband, David behind. On the way home, there is a tragic accident, and Beth takes over her sister's seemingly charmed life.
It seems, she didn't know her sister at all.

A good psychological thriller, kept me engaged from the beginning of the book. It was a little predicatable, but will appeal to fans of this genre.

There are some very unlikeable characters in the book, and some totally likeable. Even Beth, despite what she had done, stolen her sister's life, was preferable to her twin.

I do recommend.

I thoroughly enjoyed this book. It is Yvette’s debut novel and I can’t wait to read more!

It’s dark, fast paced, tense and gripped me throughout. I love the premise, it’s very original and I think it was fantastically written.

The only slightly negative thing for me was some parts didn’t feel believable. They fit well into the story but just didn’t feel realistic.

The story is told through multiple POVs and I like how you could clearly differentiate between the characters!

If you have any content triggers, I advise you to read any trigger warnings beforehand.

I recommend this to anyone who enjoys a dark, psychological thriller!

Thank you zooloosbooktours and Yvette for letting me be a part of this tour!

I give this 4 stars!

This novel is a psychological thriller that engages the reader with a compelling premise and a constant sense of suspense. Throughout the whole book! The plot is told between two twin sisters. Beth has always felt like the twin with the "bad luck," while her sister Cate seems to "have it all." So Beth has decided to pretend to be Cate. This book shows your that things are not always what they appear to be. That secrets indeed lie behind closed doors. To not always judge a book by it's cover.

Fans of Lisa Jewell and Gillian Flynn will FALL IN LOVE with this book. Filled with some unpredictable twists and turns, I can not recommend this book enough!

Thank you NetGalley for the eArc!

This book was a really great, solid thriller that kept my attention the whole way through. The tension was high from start to finish, and the plot was written and executed perfectly with lots of twists and turns thrown in along the way. I was very intrigued when I read the description for this book, and I knew I had to read it because I’ve never read a thriller quite like this one. The premise is very unique and I loved how the author executed it. The ending was also very satisfying and everything was wrapped up pretty neatly I’d definitely recommend this to other thriller fans!

The Twin Sister is one of those psychological thrillers that pulls you in from the very first line and refuses to let go. Yvette Davies creates an atmosphere thick with tension, guilt, and emotional complexity. Beth’s voice feels incredibly raw and human, and the moral dilemma she faces after the accident is both heartbreaking and impossible to look away from. Watching her slip into Cate’s life while carrying the weight of her own pain makes every chapter more gripping than the last.
The twists are sharp, the pacing is perfect, and the ending left me thinking about the story long after I finished. A truly compelling and emotionally charged read. Highly recommended.

I really enjoyed The Twin Sister. It was full of suspense, drama, secrets, and lies.
I was drawn in quickly, I found it hard to put down.

I loved Beth. She was strong, determined, and relatable.
The storyline was compelling, clever, and unique.
I loved Yvette's writing style, it was easy to read and fast paced.

This is the first book I've read from Yvette Davies, but it definitely won't be the last. I'm looking forward to reading more from this talented author.

I highly recommend.

Really good read. The plot pushes forward continually, twisting and turning to maintain engagement. Believable and convincing characters to settle into. Some unexpectedly endearing relationships develop which make this something more than a thriller, flecks of a story about a family facing challenging times. The story is stronger and more resonant for this. I read The Twin Sister over a couple of days, wanting to stay with it as the plot took another turn and the characters made their own stories. Highly recommended.
