When I think of mystery, I think of books just like this one, that gives all the thrills. This is a perfect book to snuggle up with on any day.

WOW! This is the best book I've read in a long time. I think this would make an excellent movie. I really became invested in the characters, especially Fern and "Wally" and. being a librarian, I of course loved all the library scenes. I can't believe how long it took me to finally pick up this book and read it. If it's in your TBR list, move it to the front! So good.

The Good Sister by Sally Hepworth was extraordinary! I mean… the plot was astonishing! A page-turner with plot realizations that you will not see coming. Very well done characterizations and superb writing. I wish I could read it again for the first time. This is my 3rd Hepworth and she is now an auto-buy author for me.

I received a review copy of this book from the publisher through NetGalley for my honest review. The opinions expressed in this review are completely my own.

Gahhh! This book was incredible! So fantastic, lots of twists, love that someone with neurodiversity was a main character, so much manipulation! Wish I read this sooner!

4.5 stars This is a domestic character study meets thriller meets family drama. It’s the type of book where to say too much is to possibly land in spoiler-territory, but trust that both the plot and the characters had me turning the pages well passed my bedtime!

Love her writing style. Her book The Mother In Law knocked it put of the park and she did it again. Just read it! You will not be disappointed. Two sisters Rose and Fern. Share a secret from when they are teenagers to which Rose still protects Fern til this day. Rose goes on vacation and Fern meets someone at the library where she works. She is risking everything. Family drama thriller. I enjoyed the relationship between Wally and Fern

Rose is having fertility troubles and is told by her therapist to start a diary to try to help. With this, we quickly learn that many tragedies struck her and her twin sister, Fern's, lives when they were young. Aside from a cruel upbringing in general, a young boy whom they were close with drowned tragically as well.

Told from alternating POV's from the twin sisters, it takes us on a domestic drama/sometimes thriller, and has us second-guessing who is really the GOOD sister?

A really fast-paced and fun read about sisters who would do anything to save and protect each other, no matter the cost..

Thank you to NetGalley and St. Martin's!!

This one sucked me in and was a quick read! I couldn’t put it down. The characters were great, especially Fern.

I'm a long-time reader of Sally Hepworth and enjoy her books. This one was a slow-burn thriller, taking the reader on a walk through the many waves of abuse and trials of two sisters with an addicted mother. They form a tight bond to survive and collect secrets along the way. These secrets are revealed slowly throughout the book, as we see Fern, who is neurodivergent, open up her world to a love interest. Generally, I'm not a fan of neurodivergence as a plot device and I found myself being bothered by the dependence on that trope. The sister dynamic is powerful and I was definitely drawn in and needed to know what the two had been through. Was it the best Sally Hepworth I've ever read? No. (That would be The Mother-in-Law) Was it a solid thriller worth the read? Yes, absolutely.

I enjoyed this book so much! I especially loved the main character. I can't wait for others to read this!

Oh wow, this was a good read. The author did a great job with charcter development, especially Fern! I adored her. The alternating viewpoints worked well in this book. I was definitely blown away by the ending.

Loved this one! A slow burn, family drama with great characters and a well developed story. All boxes checked. This is at the top of my list for sure!

A twisty story about two sisters who think they know each other. With alternating perspectives and short chapters, this was one I flew through. The final plot twist was a major creep factor, and left me wondering, "WTF". I really enjoyed the audio of this one too.

4.5 stars. Such a great book. Fern snd Rose are twin sisters. From the beginning you know they hold a secret and yet I wasn’t sure who was the good sister snd who wasn’t quite right. The clues were subtle and kept me curious. Sally Hepworth doesn’t disappoint yet again.

Enjoyable thriller that got super twisty! left you questioning the truth. I love Sally Hepsworth, and this didn't disappoint

Thank you to the publisher for my review copy. All opinions are my own.

Why do I wait so long on Sally Hepworth? This book has been sitting on my shelf for an embarrassingly long time and I loved every single minute of it. Per usual with Sally.

I loved that Sally brought us a character on the spectrum. As a mom of a son on the spectrum, it is always fascinating to read from their point of view. Now, let's talk about the story.

This is a family drama story with a little sprinkling of an unreliable narrator. Both of them, as it is the story of two twin sisters. I couldn't quite put my finger on what was going on...or more clearly what was amis. The story had me completely invested and I couldn't put it down. I needed to know what was up.

Luckily it wrapped up well. I had all my questions answered and felt really good about leaving these characters behind. You know what I mean....that is not always the case.

If you like family drama with a little bit of what the actual hell is going on here....Pick this one up.

THe Good Sister is the first book i have read by Sally Hepworth and i thoroughly enjoyed it!! It was a great read and i cannot wait to read more books of Sally's,

E-book provided by the publisher via Netgalley in exchange for a review.

The Good Sister is a story told through alternate points of view of fraternal twin sisters. Rose and Fern are inseparable and depend on each other. Rose takes on the caretaker role and helps manage Fern's sensory issues. The psychological twists and turns kept me interested enough to finish the book in a couple of days.

Quick, fast paced. I adore Hepworth's books. The twists and turns are not predictable and they're bingeworthy. Loved this book!

The Good Sister follows sisters Fern and Rose, who have shared the same traumatic childhood. They are twins, but extremely different. Rose is an interior designer, and Fern's protector. Fern works at the library, and is sensitive to certain lights and sounds. Told partially through Rose's diary, you learn that the two had a painful upbringing with a mother who had sociopathic tendencies. The diary tells us about a something that Fern did, that Rose helped cover up. But the two sisters' lives are so intertwined that is difficult for them to detach and realize that the past is not what it seems.

I am a huge Sally Hepworth fan. I very much enjoyed this book, and as usual, Sally is wonderful at capturing family dynamics within a suspenseful thriller. Her characters are always so authentic, and she depicted Fern in a way that was natural but also true to the characters' self. Although this was not my favorite Sally Hepworth novel, I would still highly recommend this one. I had a little trouble getting into it with the past and present POVs for some reason, and after a slow start I just wasn't as hooked as normal. This is nothing about the book or writing, I think this was more of my own preferance.
