throughly enjoyed this book! It was a quick read and kept me on my toes! about 60% into the book I truly was not sure where the story was going to go but it was such a fun ride!

Thank you for this ARC!
I loved this book! It got my attention right at the beginning . I loved following the 2 different point of views between the sisters. I did not see that ending coming . Definitely recommend!!

I flew through The Other Sister by K.D. Wong. The short chapters made it easy to keep saying “just one more,” and before I knew it, it was way past my bedtime.

The story immediately pulled me in: Madison takes over the life of her wealthy identical twin after her death, stepping into a mansion, a marriage, and a life she’s always envied. But the deeper she gets into Amelia’s world, the more obvious it becomes that nothing is quite what it seems, especially to Amelia’s son, who knows Madison isn’t his mother.

I’ll be honest… Madison drove me crazy. She spends so much time justifying her decisions and making objectively terrible choices that there were moments I wanted to shake her. But at the same time, that frustration made the story incredibly hard to put down because I needed to see how far things would spiral.

This one had such an unsettling atmosphere throughout. There’s the constant tension of being watched, the pressure of maintaining the lie, and the growing realization that the people with the most power are often the most dangerous. The commentary on wealth, influence, and the darker side of the tech industry gave the story an extra layer that made it feel even more disturbing.

One of my favorite parts of the book was the reminder that we rarely know what’s really happening behind closed doors. The story challenges the narrative people create in their heads about other people’s lives and relationships.

If you like messy characters, psychological tension, revenge, family secrets, and thrillers that keep you flying through chapters late into the night, this is definitely worth picking up.

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.

the other sister indeed. this is one of those reads where you get settled, in give your hands a good rub together in the eagerness to see how this is all going pan out. and just enjoy the ride that is about to get tricky, messy and probably a little dark. im in...
can one sister who envies her sisters lifestyle step into that role? well, the death of said sister is about to give her the chance to find out. the elite life she has always envied is now hers. happy days right? ermmmmm...
Madison may have stepped into the world of large house and money. but she has also stepped into something so much more. money in this case is noooot going to buy her happiness. and as for her sisters little boy, well hes more knowing than she thinks.
yup everything is about to get complicated.
there were times i wanted to shake Madison. but then i had to give myself a little shake, let it go, her choices are whats making this story so great, haha. enjoy the ride reader even the messy decision making. and in its own way this is what makes it so much of page turner. because the deeper you get in the chaos the more the spiral become addicting to read about. and then i was just needing to know how this was or could ever get to in the end?
the family dynamics in this one is eeeeeeek. the tension and things held onto over the years made the air practically crackle. resentment doesn't even cover it.
i love how even at the beginning i was wondering how or what path it would take. and with each new moment of the book it got more and more delicious. and my suspicions and thoughts on the good or bad, which side to take was forever flip flopping with each new unravelling. there being a small child and those attachments added another layer. one that made me as a reader even more tense and care what might happen next and in the end.
the issue of money will always bring tension to families. never fails to cause trouble. and we see that here. but so does love. so does people when you care.
once again we are met with the often darker layer that sits beneath money. on how often it buys you power and the ability to sit in the darkness and somehow get away with it. money buys the mask and protection. for those victim to that it can be terrible. and the sheen very quickly wears thin.
i genuinely couldn't see where this was going. how could it possibly end with any sort of softer landing? and was racing through faster than my brain could take it in at one point and had to tell myself to slow down and breathe!
an excellent psychological thriller which is my favourite kind. bring on more from this author.

This book gives you different perspectives from both sisters which I enjoyed.
Kept me reading until the end.
Would recommend this book to any thriller lover
Thanks Netgalley for letting me read this book for an honest review

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.
3.75 stars

A good fast paced read which grabbed me from the start.
I enjoyed the perspective between the two sisters.
Great writing.
My thanks to netgalley and the publisher for my copy.

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.

Thank you to NetGalley for a copy of this book. I had no idea what to expect going into this one and I have to say it really keep me interested! I couldn't put it down. The twists and turns were so good.

A tragic car accident opens the door for a twin to take on her sister’s seemingly perfect life while losing her own hard scrabble one. Unfortunately the golden life is really just a gilded cage.

The pacing held my interest, and I had a hard time putting this book down. Some twists were a bit predictable, though others came out of nowhere. I had to suspend a lot of disbelief in the first chapter. The book took some dark turns, and I rooted for Amelia/Madison the whole way.

Thank you to Net Galley and the publisher for an advance copy. Opinions in this review are my own.

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.
