The Other Sister
She stole her sister’s life. Now she’s trapped in it.
Madison Lockwood is a nobody—a bartender from Albany with a checkered past and a mountain of debt. Her identical twin, Amelia, is living the dream as the wife of Vince Warren, a tech visionary with a private estate and a fortune that could buy the world.
When Amelia dies in a tragic accident, Madison is offered the chance of a step into her sister’s designer shoes, maintain the illusion of a happy marriage, and claim the luxury she’s always envied.
Vince Warren and his circle of elites are fooled by Madison’s performance, but one person sees the Amelia’s six-year-old son, Jonah. He knows she isn't his mother, and his silent, watchful gaze is a ticking time bomb.
As the walls of the mansion begin to close in, Madison finds herself caught in a high-stakes game of psychological cat-and-mouse. Every look is monitored. Every word is measured. And the more she transforms into Amelia, the more she realizes that her sister’s life wasn't a fairy tale.

The Other Sister is a fast-paced domestic psychological thriller that features identity theft, deceit, and buried secrets.
The story follows Madison Lockwood who does a quick Parent Trap-esque switch after a car crash killing her twin sister, Amelia. She thinks Amelia has it all with the perfect husband Vince, beautiful son Jonah, and lots of money. However, she soon discovers things aren’t quite what she expected.
Whilst this was a quick read for me, and I was invested, I was able to predict much of the plot. I also wasn’t a huge fan of the main character Madison. She seemed a bit naive and made some questionable decisions. I didn’t really feel like she felt the impact of her decisions, even after everything was over. However, I could definitely feel this woman’s fear and struggle.
Jonah was a bright light in the book for me. He was smart (perhaps too smart for a six year old, but I didn’t mind!). He was sweet and I felt for the poor kid.
There were many times in this book that I got a flashbacks of reading The Housemaid (which ironically I also finished in a day).
Overall, this book did indeed keep me turning the pages, but I have a feeling that this one will fade amongst the shelves for me.

The other sister is a domestic thriller/suspense that follows Madison, who has not had the best luck in life, while her estranged twin sister, Amelia married a rich tech visionary. After their mother passes away, Madison and Amelia reunite; unfortunately, their reunion is cut short when they get in a car accident resulting in the tragic death of Amelia. At the site of the accident, Madison realizes that the only way out of her miserable life in Albany is to step into Amelia's life of luxury. As she lives the luxury life at the estate with Amelia's husband and son, she realizes that there is a lot that Amelia was hiding from her.
Although the story is quite predictable, I thoroughly enjoyed the author's interpretation and the pace of the story.

I really enjoyed this book and I felt the pacing was good, quick enough to keep me reading one more chapter. Even though I had a suspicion early on about the path it would take, it was still fun to follow the path anyway. The villain's methods were very creative and that added to the suspense. The main character is interesting, though a little morally gray, especially at the beginning. I did get tired of the numerous references to how much everything cost or was worth - I get it, everything in a billionaire's lifestyle costs more than everything in a waitress' lifestyle and after about a dozen comparisons that got a little old. Otherwise, fun beach read book.

This was a book I had to keep reading and just wanted to know more details! Madison was an okay character. The villain was diabolical and I wasn't sure how the MC was going to escape. The ending was good.

What I Liked:
* The pacing was really good. The story kept moving forward, and I never felt bored while reading.
* I constantly found myself wanting to read “just one more chapter” to see what would happen next.
* There were a few twists that genuinely surprised me, which I appreciated. One example was the reveal that Jonah’s robot was actually being used as a recording device where Amelia confessed the truth about Vince.
* I also liked that Jonah knew from the very beginning that Madison was not actually Amelia. It added a lot of tension and emotional weight to the story.
* The scene between Jonah and Madison in Chapter 32 was especially heartbreaking. The moment Madison admitted she wasn’t his real mother, and Jonah realized his mom was never coming back, was very emotional and honestly one of the strongest scenes in the book.
What I Didn’t Like:
* This is more of a personal preference, but there was too much strong language for my liking, as well as an explicit sexual scene, even though it was skipped over quickly.
* I had a hard time connecting with Madison as a character. Honestly, both sisters were flawed, but Madison especially frustrated me. Her first instinct after Amelia’s death was to focus on taking over her sister’s life and identity while Amelia’s body was literally beside her. Even though she developed throughout the story and eventually showed genuine care for Jonah, some of her behavior still made it difficult for me to sympathize with her.
* Some parts of the story were also predictable. It was obvious early on that Vince would turn out to be the villain. I also suspected from the beginning that Amelia had been isolated by Vince and forced to cut contact with her family so she would depend entirely on him. Another thing I saw coming was that Vince already knew Madison was not Amelia.
* I personally wish both Vince and Madison had faced real consequences for their actions and ended up in prison. I also wish Jonah had been placed with a loving and stable family by the end.
*thank you to Netgalley, the publisher and the author for the opportunity to read the arc of the book before release date*

Really good one. Kept me thinking about it when I wasn’t able to be reading. The plot twist I didn’t even almost expect.
July 14, 2026
Massive thanks to K.D. Wong, Obsidian Books and NetGalley for this advanced copy of The Other Sister. This review is being left voluntarily and all opinions expressed are my own.
Let's just say that main character Madison hardly endears herself to you as the reader by her actions at the start of the book. She is clearly not going to be the hero of the story if you judge her on how the story starts.
Her disdain towards her much more successful sister is immediately apparent. The book starts with a car accident that gives her the chance to have the life she envies, her sister's.
Madison soon realises, however, that her sister's life might not have been as perfect as it seemed from the outside. Even if she wants to keep the illusion going, her nephew (now pretend son) may be the biggest obstacle to her securing her dream life. I really enjoyed that dynamic as the story progressed.
I loved the pov switch halfway through the book. Although its a much-used tool in thrillers, I feel the author used it really well here and it gave a completely different spin on the action.
I really enjoyed this book when the pace picked up towards the end and there were some really surprising events that I didn't see coming. It was definitely very vivid and cinematic.
Overall, just a really solid and engaging thriller that felt easy to read and wasn't hard work at all. I'd be interested to read more by this author.

Amelia and Madison are estranged twin sisters, the book opens in the aftermath of a car accident, with Madison making the decision to swap places with Amelia and step into her seemingly perfect life, but the grass is not always greener on the other side and the perfect life is closer to a gilded cage, can Madison escape or will her new life be the death of her.
This gave me the housemaid by Freida McFadden vibes.
I read the other sister in one day as it was a shortish book at 300 pages. I enjoyed but didn’t love it, the chapters were short and the pace was quick but I guessed the twists and felt that the ending was too rushed, I wanted this to be more drawn out to feel satisfied with the ending.
I didn’t understand this sentence “and the ink on her phone screen wouldn’t even be dry before she was calling our inner circle” how does ink dry on a phone?
Overall, I enjoyed it enough that I would read something from KD Wong again, but I’m not rushing out to read another book by him.
Thank you Netgallery and Obsidian books for the opportunity to read and review this book.

K.D. Wong absolutely had me hooked and guessing the ending the entire time!
Unhinged sisterly love? Family secrets? A seemingly perfect husband who may not be so perfect? YES.
If I had to sum this book up in two words: Imposter & Unhinged. But even that barely scratches the surface because the twists just kept coming, and I couldn’t wait to see what would happen to that slimeball husband!
The pacing made this such an easy, addictive read. I flew through it and stayed fully invested the entire time. Fans of The Housemaid and other fast-paced psychological thrillers will definitely want to pick this up.
One minor critique: about halfway through, the POV changed unexpectedly, and it took me a moment to adjust and fully understand the transition. Once I settled into it, though, I appreciated how it added another layer to the mystery and helped clarify the tension between Madison and Amy.
Overall, this was a twisty, entertaining thriller packed with dysfunctional family dynamics, secrets, and deception. Definitely a fun ride for thriller fans who love unreliable characters and shocking reveals.
Thank you to NetGalley and the publisher for the ARC in exchange for an honest review. Bravo, K.D. Wong!

Review of Advanced Reader Copy from NetGalley
Madison Lockwood switches lives with her now deceased twin sister, Amelia Warren, after they were in a deadly car crash. Madison struggles daily and has nothing, but her obnoxious sister was married to a billionaire. All Maddy has to do is pretend to be her dead sister for a few weeks, enough time to get enough money to start a new life. What could go wrong?
As Madison tries to step into Amelia’s shoes, she tries to convince Amelia’s husband, Vince and son, Jonah that she is her twin sister. As time moves on, Madison learns her sister’s life wasn’t luxurious as she once thought, but actually filled with deep, dark secrets.
I very much enjoyed the premise of this story. The pacing creates an easy read and the author builds a tremendous amount of enjoyable tension as the book goes along. I think there was some unnecessary repetitiveness in a few parts of the book, but overall, it was a twisty thriller with a main character that isn’t exactly likable but definitely tolerable, complete with a satisfying ending.

What a fantastic, twisty, suspense-filled read! This was my first book by this author, but it definitely won’t be my last. The story is fast-paced, engaging, and anything but predictable. I thought I had it figured out several times and was convinced I knew where the author was taking the story, but I was wrong every single time.
The twists kept coming, the tension never let up, and I found myself completely invested from beginning to end. If you enjoy books that keep you guessing and leave you shocked by the reveals, this one is absolutely worth picking up.

Thank you to K.D. Wong, Obsidian Books, and Netgalley for a copy of The Other Sister in exchange for an honest review.
Twin stories already come with built-in chaos. There’s always the prettier one, the smarter one, the favorite one, the one secretly one inconvenience away from a full psychological spiral. And Madison? Madison packed her bags and took the express train straight to Delusion Junction. 🚂
After a tragic accident kills her twin sister Allison, Madison decides this is less “time to grieve” and more “time for a lifestyle upgrade.” She slips into Allison’s life, convincing herself she deserves everything her sister had. The house. The husband. The life. The whole thing felt like watching someone try to wear another person’s skin while pretending it fits perfectly, and honestly? It was eerie in the best way.
The atmosphere in this book was easily the strongest part for me. There was this constant uncomfortable tension humming underneath every interaction. You know the kind where you want to yell at the characters to run, hide, call the police, call literally anybody. The author did a fantastic job building that creeping sense that everything was wrong even during the quieter moments. It had that cold, unsettling energy where you can practically hear ominous violin music in the background while reading.
Now Madison… whew. I struggled with her. A lot. I understand resentment. I understand jealousy. I understand feeling overshadowed by a sibling who seems to have won the genetic lottery and the life lottery at the same time. But this is your TWIN SISTER. Allison dies and Madison’s emotional response felt less like grief and more like, “Well… finders keepers.” I needed even a crumb of humanity from her and instead she served selfishness with a side of identity theft deluxe. She was manipulative, obsessive, and deeply unlikeable. Which, to be fair, may have been exactly the point. But connecting with her emotionally? Absolutely not. Madison was out here acting like morality was an optional subscription service.
Poor Jonah though. POOR JONAH. That kid broke my heart. Out of everyone in this story, he felt the most genuine and emotionally real. While the adults around him were busy spiraling into obsession, lies, and absolute chaos, Jonah was just trying to survive it all. His grief, confusion, and vulnerability grounded the story and honestly made some scenes even more unsettling because you realize how deeply all of this affects him. Every time he appeared, I immediately became more invested because he was the one character I truly wanted to protect.
And Vince… listen. The author got me GOOD with Vince. At first I thought he was charming, supportive, maybe just a little odd around the edges. Then slowly the mask started slipping and suddenly every interaction with him felt like accidentally stepping into a basement with no windows. That man had me side-eyeing every sentence by the end. A walking red flag wrapped in charisma and bad intentions.
As a thriller, this one lands more in the “psychological slow-burn suspense” category than edge-of-your-seat shocker. The biggest issue for me was that the story felt very transparent early on. You can tell almost immediately who the good guys and bad guys are supposed to be. The mystery isn’t really who is dangerous, it’s more waiting to see how far things are going to go. Some readers will love that simmering dread, but personally I wanted a few more surprises thrown into the mix. The twists themselves weren’t jaw-dropping because the book practically winks at you from chapter one saying, “You already know this is going to end badly.”
Still, despite my frustrations with Madison and the predictability, I can’t deny this book kept me reading. It was unsettling, compulsively readable, and packed with enough uncomfortable tension to make me suspicious of every character breathing on the page. It’s the literary equivalent of watching someone slowly walk onto thin ice while you scream internally the entire time.
Final Verdict: The Other Sister is a dark, eerie psychological suspense filled with obsession, resentment, identity theft, and enough family dysfunction to power an entire therapy convention. Madison drove me absolutely insane, Jonah deserved better, Vince belongs on a watchlist, and while the thriller elements were a little too obvious for my taste, the atmosphere and tension kept me hooked until the very end.
⭐⭐⭐ 3 stars. Twisted, creepy, and frustrating in equal measure.

Review of advance copy received from NetGalley
I have not read any other books by this author but I did just put another one on my tbr.
Brief Summary: Madison is very angry at her twin sister. Her twin got married a few years ago and after that she kind of dropped out of Madison and their mom's life. Amelia didn't even show up for their mom's funeral service nor helped in any way with her care. Amelia married a very very rich man but offered no help to the rest of her family. After their mom dies, Madison makes her way to Amelia to confront her, but is rushed into a car and speeding down the highway and then they end up in an accident where Amelia is killed. Madison decides to take Amelia's place, Madison has always been the twin that struggled, never had any money, or nice things and had to work endlessly to even make ends meet and to take care of her mother so she feels that this is her opportunity to get what her sister had. Her plan is just to be Amelia for a short period of time until she can make off with some riches to set her up for the rest of her life. However, she begins out liking being Amelia and then she stays longer than she intended but then things start to not be as they originally seemed. I don't want to go much further as to give away spoilers, but I am just going to say that a little boy and a toy robot later on become the star of the story. I would just highly recommend reading the book!
Thoughts: 5 stars, this one hooked me from the very beginning and didn't let go. Gave me heart palpitations in the best way, so suspenseful and as the further I got in the story the more my heart raced and the tension soared. I was on the edge of my seat the closer to the end I got, I absolutely loved how it went and how it all wrapped up in the end. I could have easily read this book in one sitting and really wanted to but I do work but I was anxious to get back to it and see how it all worked out. I am very interested in reading more books by the author. I could see this story being made into a movie.
Thank you Netgalley and Obsidian Books for the complimentary copy of the story.
Brief Summary: Madison is very angry at her twin sister. Her twin got married a few years ago and after that she kind of dropped out of Madison and their mom's life. Amelia didn't even show up for their mom's funeral service nor helped in any way with her care. Amelia married a very very rich man but offered no help to the rest of her family. After their mom dies, Madison makes her way to Amelia to confront her, but is rushed into a car and speeding down the highway and then they end up in an accident where Amelia is killed. Madison decides to take Amelia's place, Madison has always been the twin that struggled, never had any money, or nice things and had to work endlessly to even make ends meet and to take care of her mother so she feels that this is her opportunity to get what her sister had. Her plan is just to be Amelia for a short period of time until she can make off with some riches to set her up for the rest of her life. However, she begins out liking being Amelia and then she stays longer than she intended but then things start to not be as they originally seemed. I don't want to go much further as to give away spoilers, but I am just going to say that a little boy and a toy robot later on become the star of the story. I would just highly recommend reading the book!
Thoughts: 5 stars, this one hooked me from the very beginning and didn't let go. Gave me heart palpitations in the best way, so suspenseful and as the further I got in the story the more my heart raced and the tension soared. I was on the edge of my seat the closer to the end I got, I absolutely loved how it went and how it all wrapped up in the end. I could have easily read this book in one sitting and really wanted to but I do work but I was anxious to get back to it and see how it all worked out. I am very interested in reading more books by the author. I could see this story being made into a movie.

[ARC REVIEW 📖]
The Other Sister
Author : K. D. Wong
This 38-chapter novel begins w/ Madison Lockwood, a bartender working 12-hour shifts to pay for her dead mother's debts, & Amelia Warren's twin sister, who got caught up in a life-or-death situation because of a car crash accident. The Tesla her sister drove had a malfunction & the driver's airbag was not activated. With Amelia the driver dead on the spot, an idea hit her as she calls 9-1-1 for emergency. Could she actually pull it off? Take over her dead sister's life?
Wow just wow! I can't believe how many times I stopped to breathe due to the suspense build up every single time Vince Warren tries to analyze her if she is really the "Amy" he knows or not. Jonah too, Amelia's son, as if he has a sixth sense. Good god I kept getting goosebumps, the Warren residence gives me the creeps. Even worse after finding out she was actually Madison. 😱
Vince is a total psychotic freakshow. Period. Obedience & discipline plus punishment through physical & mental torture as the highest form of love? Hell nah. 🤚 Dang this rich dude is a total red flag & a damn trap. 🚩
I was rooting so hard in the end for Madison to put an end to all the nightmares Vince has been causing. It's a good thing Jonah (& his robot Charlie) turned around & went w/ his auntie to try & escape that hell of a hole. Revenge is a dish best served cold indeed, especially if it's done in the Time-Out Room. 👌 Outstanding read, I enjoyed this thriller of a novel! 👏 I hope you are proud of your sister Amelia, wherever you are. 🕊
Thank you Netgalley, Victory Editing Netgalley Co-op, & to the author for the opportunity to read! 🥹🫶
4/5 ⭐️⭐️⭐️⭐️
P.S.
There is an excerpt to the author's latest pyschological thriller "Red Flags" at the end of the novel. 🤩

Thank you to author, K.D. Wong, for providing me an early copy of this book.
📚Book: The Other Sister
✍🏻Author: K. D. Wong
🌀Genre: Psychological Thriller
📃Pages: 303
Publication Day: June 26, 2026
She stole her sister’s life. Now she’s trapped in it.
Madison Lockwood is a nobody—a bartender from Albany with a checkered past and a mountain of debt. Her identical twin, Amelia, is living the dream as the wife of Vince Warren, a tech visionary with a private estate and a fortune that could buy the world.
When Amelia dies in a tragic accident, Madison is offered the chance of a lifetime: step into her sister’s designer shoes, maintain the illusion of a happy marriage, and claim the luxury she’s always envied.
Vince Warren and his circle of elites are fooled by Madison’s performance, but one person sees the truth: Amelia’s six-year-old son, Jonah. He knows she isn't his mother, and his silent, watchful gaze is a ticking time bomb.
As the walls of the mansion begin to close in, Madison finds herself caught in a high-stakes game of psychological cat-and-mouse. Every look is monitored. Every word is measured. And the more she transforms into Amelia, the more she realizes that her sister’s life wasn't a fairy tale.
It was a cage.
💜What I Loved:
📖 Unputdownable
💨 Fast paced
😱Unhinged
⚫️ Dark
😨Eerie
😰Feeling of dread
💔What Didn’t Work For Me:
🎭Main character
🌪️Twists not as twisty
📖 Rating: ⭐️⭐️⭐️⭐️ (4/5)
👩🏼⚖️Final Word:
So WOAH… this was unexpected!! I went in blind which I love to do!! I really enjoyed this book and had a hard time putting it down. For me, it was fast paced and I could not wait to see what happened next. I loved how unhinged it was and the feeling of dread while reading it. I had some issues with the main character and her choices (no spoilers). I also was looking for the twists to be bigger, more twisty and more shocking. Overall this is a great read! If you like psychological thrillers, that are unputdownable, are dark and unhinged, give this book a go!

The Other Sister takes the classic twin‑swap premise and sharpens it into something darker, more psychological. Madison steps into Amelia’s life with the kind of hunger that comes from years of scraping by, and the book captures that uneasy blend of envy, guilt, and awe as she crosses the threshold into her sister’s world. The estate, the wealth, the curated perfection — it all feels intoxicating at first, but there’s a coldness to it, a stillness that hints at the truth long before Madison is ready to see it.
What really elevates the story is Jonah. His quiet, watchful presence is unnerving in the best way — a child who sees too much, understands too deeply, and becomes the one person Madison can’t fool. Every scene with him feels like a held breath, as though he’s the fuse running toward the inevitable explosion.
The mansion itself becomes a kind of gilded trap, every corridor echoing with Amelia’s secrets. The more Madison tries to inhabit her sister’s life, the more she realises she’s stepping into a role that was already suffocating someone else. The tension builds in these subtle, psychological beats — a look held too long, a question asked too softly, the sense that someone is always listening. It’s a slow tightening of the walls, and by the time Madison understands the truth, you can feel the cage closing around her too.
A sleek, unsettling thriller about identity, desire, and the dangerous fantasy of stepping into someone else’s life. Perfect for readers who love their domestic suspense with sharp edges and a lingering sense of dread.

ARC Review ✍️
Title: The Other Sister
Author: K. D. Wong
Genre: thriller
Pub. date: 26th June 2026
Summary:
Madison and Amelia are twin sisters. Madison took care of their mother, she works as a bartender and now has been left with debt after their mother died. Amelia is married to a rich man, she's always dressed well and it seems she doesn't have to worry about anything. Sisters get into a car accident in which Amelia dies and Madison, trying to run away from her money problems, literally steps into Amelia's shoes. However, is everything as calm as it seemed or has Amelia been keeping secrets? Maybe Amelia's life has never been as easy as Madison has thought.
Opinion:
The author places the characters in the middle of the action in the first chapter. The decision Madison has to make seems like a cruel one. However, I see why she does what she does. Once she settles in a new home with a rich and handsome husband, things start taking a turn for the worse. I loved the plot twists and the quick pace. Amelia's perspective was well written into the script, everything became clear for the reader as well as her twin sister Madison. The book could definitely be read in one sitting, it's short and once you start, it's difficult to put down! The ending left me speechless but at the same time the character deserved it. I wish I could say more but I mustn't spoil it. I recommend reading the book!

The Other Sister by K.D. Wong (June 2026) [reading in May]
204-page Digital Copy story pages 12-196
Uncorrected Proof ARC/ADC courtesy of Obsidian Books
Genre: Psychological Thriller, Mystery
Rating as a movie: R
Featuring: Sisters, Twins, Imposter Trope, Secret Identity, Affluent People, Family Dynamics, California, Sex, Marital Conflict, Violence, Abuse, Excerpt from Red Flags, Bibliography for K.D. Wong
My rating: ⭐️⭐️⭐️👭🚗
My thoughts: 🔖Page 35 of 204 Chapter 6 - This story is far more interesting than the other book I was reading, although it does have a bit of a popcorn thriller storyline, and the popcorn is a little stale.
I picked this up because of the amazing plot. If you are a fan of Behind Closed Doors or McFadden you will enjoy this fast-paced popcorn thriller. It's a quick read and she manages to fill in every plot hole you think you've found. I did read chapter one of Red Flags and it sounds promising.
Recommend to others: Likely. If you are into quickpace fast fiction this is a perfect story if you want something more complex that takes it's time, this isn't that.

Review of advance copy received from NetGalley
The Other Sister by K.D. Wong is a highly unhinged, atmospheric, and delightfully toxic psychological thriller that, despite its predictable, unoriginal tropes, remains a compulsively readable tale of obsession and identity theft.
Drawing heavy thematic comparisons to domestic suspense giants like The Housemaid and Behind Closed Doors, the narrative delivers a masterclass in family dysfunction, resentment, and manipulation. For seasoned thriller readers, the plot beats are entirely transparent; the central illusions, game-playing, and ultimate backstory reveals offer very little genuine shock or surprise. However, the novel triumphantly compensates through its exceptional world-building and palpable atmosphere. Wong expertly injects a constant, unsettling tension into even the quietest interactions, creating a creeping sense of dread that hooks the reader from the very first page.
While it heavily treads familiar psychological territory, its rich, uncomfortable suspense and rapid pacing make it an addictive, highly entertaining cat-and-mouse game. For fans of high-drama, formulaic domestic thrillers elevated by an impeccable, moody atmosphere, this dark ride earns a comfortable 4 toxic stars.

What a rollercoaster ride! I saw The Other Sister by K.D. Wong in the "Read Now" section on netgalley and I knew I had to read it immediately!
I started this book while my schedule was hectic, so I took my time reading it. The buildup was medium paced, and as I found myself quite a struggle to commit to the plot, at that point of time I could already grasp that something was wrong and knew which character to suspect (🤭), then I started to feel the nerves.
However, once I reached Chapter 15, it became unputdownable! I made time for it, pausing other books just to focus on this story. On Madison, Amelia, Jonah, and Vince. The revelation was so sickening, and I was gobsmacked throughout. I even started planning a getaway for them, as if I was there in the scene with them.
It felt helpless at first, but the revenge served was so sweet. I couldn't believe the amount of thrills and supense that I felt from the beginning, were finally rewarded with such a peaceful ending. I'm so happy for Madison and Jonah 😭😭😭
This book is expected to release on June 26, 2026 so please keep your eyes on this masterpiece, everyone!
Thank you author for this story, and now I can't wait to read Red Flags!

Thank you to NetGalley for the opportunity to read this early copy of The Other Sister by K.D. Wong in exchange for an honest review.
I flew through The Other Sister. I love a story about twins. You can do so much with twins in storytelling. K.D. Wong had me absolutely addicted to this book. When I couldn’t be reading I was thinking about what could possibly happen next. I had no idea.
After an accident that kills her sister, Madison decides to pretend to be her sister Amelia and take over the life she thought was perfect. She soon finds out that Amelia’s life was anything but perfect.
This book had me at the edge of my seat the whole time. And it ended better than I expected or could have imagined in my own head. I love that the chapters where short, that always keeps me reading for some reason. This is the first book by K.D. Wong that I have had the pleasure in reading, but it will not be the last.

This book pulled me in pretty quickly and honestly, what a fun ride. The family drama, secrets, and tension between the sisters kept things moving, and I liked never being completely sure who was telling the truth.
The sister relationship was the best part for me. It felt layered and tense, with years of resentment sitting under every conversation. I kept waiting for everything to finally come out, and it was fun watching everything slowly unravel.
Some parts were more predictable than others, and I wanted a little more from a few of the characters, but I still had a good time with it and flew through it in a couple sittings.

The Other Sister by K.D. Wong is a heartfelt, realistic, and beautifully told story that drew me in from the very first chapter. The emotional honesty in this book is incredible — the characters feel so genuine, their struggles and connections written with a tenderness that makes every moment resonate.
The storyline is fantastic: engaging, layered, and full of quiet depth. It balances raw emotion with a grounded sense of real life, making it impossible not to connect with the characters and their journey. It’s one of those reads that lingers in your mind long after you’ve closed the final page.

The Other Sister by K. D. Wong was a great quick read and so addictive, once I read a few pages I knew it was going to be a good book, especially as you jumped right into it with a great twin-swap storyline. Ot was full of brilliant twists and turns that will have you turning the pages of your kindle to find out what happens next. Excellent read and I ended up reading it in one sitting. I loved it.
This was my first book I have read from this author and it definitely won’t be my last.
I Highly recommend the other SisTer. 5 ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

Holy crap…. where do I even begin????
from the first line, I was instantly hooked. Like I read 64% in the first night and finished it the next morning. This was absolutely incredible. The short chapters were the absolute way to go, it kept making me want more and more. The way the storyline and the plot flowed was so satisfying and the ending had me screaming. I absolutely loved everything about this book, I am going to be recommending it to everyone I know. A solid 5/5 star for me.

What to say?
It was such a good thriller that had me hooked from page one.
Also, payback is a b**ch.
I completely loved this thriller and omg the ending 🥲
I 1000000% recommend if you love thrillers, blood and gory. Overall I'd totally recommend to almost everyone. Unless thriller isn't your thing.
All I can say is that karma does come around to those who need it and are looking for a taste of their own medicine.

This was an interesting take on an identical twin plot. I personally find twins to be fascinating, and this book was no exception. Loved the concept and the characters were interesting. My only real criticism would be the excessive use of cost comparisons, in the context of describing items as being worth x number of months’ rent, x number of hours spent working at the bar, etc. The comparisons grew tired after a while.
Review of advance copy received from NetGalley
This book is about a woman who wanted a better life, but she didn’t imagine the consequences of this. It reminded me of “The housemaid” by Freida McFadden. This book is good in total. It has a pair of plot twists. But there are some predictable things ( for example, a true story of Madison’s sister or the true identity of Warren) and some events, that are far-fetched on my opinion. Especially in the end.
This thriller is good but not the best
