Told from multiple point of view, this is a missing woman mystery with tons of plot twists and an unexpected ending. Perfect for fans of Lisa Jewell and Kiersten Modglin. I saw the book is being turned into a film, and I can’t wait. It will translate perfectly to the screen.

Thanks for the opportunity to read in advance!

Thank you for allowing me to read this book as an ARC.
This is the first book I read of this author.. I absolutely loved this book. It was so good and the twists and turns were totally unexpected. Every time I thought I had things figured out,.the story took a different turn. The ending was a huge surprise...but an amazing one!
The characters were greatly developed and the protagonist was not too far in the foreground. I loved the different chapters written from different points of view. I
I will definitely keep looking and reading this author's other books! A 5 🌟 read for me!

INCREDIBLE story! 5 out of 5 highly recommend. What a wild ride. Told through multiple POVs, we get a glimpse of the wealthy, beautiful and elusive residents. Looks can be deceiving! One of the families, known as the Blackwells, offers their pool house to Maddie to live in. When her sister Alex tries to connect with her, her phone calls go unanswered. Maddie and Alex meet once a year in the Hamptons to celebrate Alex's birthday. She would never miss it unless...
I cannot give anything away, but this absolutely needs to be on your must read list.
Huge thank you to Stephanie DeCarolis, NetGalley, and Random House Publishing Group for this advanced copy.

Older sister Maddie has disappeared. When younger sister Alex goes looking for her she finds lots of mystery and intrigue at the Blackwell home, Maddie's last known place. Alex becomes involved, just as her sister did with the family and finds lots of mystery around the family and the disappearance of her sister. What did Maddie find out or know about the family that has caused her disappearance. Will Alex disappear as well? This is a really great mystery and one that will keep you turning the pages until its secret is revealed. Thanks to #NetGalley#ThePerfectSiser for the opportunity to read an review this book.

I wasn’t expecting the ending on this one. Had multiple twists throughout the novel. I wouldn’t classify it as anything earth shattering or anything but a quick read that had some thrills.

I received an ARC of this book from Netgalley and Random House Publishing Group - Ballantine in exchange for an honest review.

Alex and Maddie have always been super close sisters until their mom dies and they have a falling out. When Maddie misses Alex's birthday, something Alex knows she'd never do no matter what fights they've had, Alex heads to the Hamptons to look for her sister in the last place she knew she was. As Alex is taken in by the wealthy Blackwell family, the same ones Maddie was staying with, she begins to suspect that someone there knows what happened to her sister.

This book is full of twists and turns and kept me guessing.

I really liked the premise of this but the thought the execution was a little messy and drawn out. I enjoyed this for the first half but started losing interest because it just felt like nothing was happening. I wish the characters were a little better developed so I could resonate with them a bit more. The reveal just didn't land as hard as I was hoping. Overall, I thought this was okay but not one of my favorites. Thank you to NetGalley and the publisher for this ARC in exchange for an honest review.

I definitely meant to write this review months ago!

After not hearing from her older sister Maddie for a period of time, Alex goes to the Hamptons to try to find her. Their relationship has been rough since before their mother died, but she knows something is wrong.
When Alex arrives and finds out that she has been living with a wealthy family, it seems that her sister may have had many secrets. She is invited to stay with the Blackwells while she continues her investigation and goes headfirst into discovering her sister's secret life.
But where is Maddie now and is her disappearance connected to the disappearance of another young local girl?

I really enjoyed this novel. It kept my attention and really had multiple twists. I was not expecting the ending but also was hoping for more. But still, I will rate this 4 stars and recommend to others!

The Perfect Sister was a fun mystery that kept me guessing. I wasn't sure who I could trust or what anyone was hiding but everyone felt shady! I really liked that there were so many different viewpoints and that we got to hear from most of the main characters. It was a great way to convey the story and give off red herrings.

The setting was great and I appreciated the details about the Hamptons. I liked being pulled into the world of wealth and power and I thought DeCarolis did a good job of intersecting that extreme with the people who serve and support them.

I listened to this book on audio and appreciated the use of various narrators. The energy and tone were great and kept the story exciting and entertaining.

There were certainly some moments where suspension of belief were necessary, but I liked how everything played out. It was fun and really well done.

Thank you to Ballantine/Bantam for the copy.

The Perfect Sister follows Alex, who, when she doesn’t hear from her sister, goes to the Hampton to find her. There she meets the Blackwell family, with whom Maddie had formed a connection. As she stays with the Blackwells herself, Alex quickly learns that the family is keeping secrets from her… and so are some of the friends she thought she could trust.

The atmosphere and setting of the book are well done, and Stephanie DeCarolis does a beautiful job with her descriptions of the oceans and cliffsides, but the storyline is far too melodramatic and soap-opera-esque to be realistic. This is a quick read for a summer escape, but too long-winded and with too many subplots to keep track - 2.5 stars, rounded to 3

Maddison is missing. Alex, her sister, has gone to look for her. Her last seen location was at Blackwell Manor. What was she doing here? This place is a mansion, and surely Maddison can not afford a room here
The Blackwells open their home and answer Alex's questions. They were sure Alex said she was leaving. And now they have offered Alex a place for the night. Besides, it is raining outside
Their adult children, Lilly and Theo, both seem kinda strange but harmless. The mom surely doesn't want Alex snooping around, and the father, James, is surely hiding something
Someone knows what happened to Maddie, and Alex isn't leaving until she gets some answers

Unfortunately, this one couldn't pull me in. There were a lot of narrations and the shocking moments fell flat for me.

I love books about the bonds of sisters and books where someone has to travel somewhere else This delivered. It was not the best book I've ever read but I have no regrets about the time spent reading it.

Alex has come to the Hamptons in search of her older sister, Maddie. Shortly after their mother’s funeral, Maddie left home and went to the Hamptons. Now no one has seen or heard from her in days. Before her disappearance, Maddie was residing in the Blackwell’s pool house. Alex goes there and finagles an invitation to stay in the pool house until she’s ready to leave. The novel, with many narrators telling their stories. Readers will find themselves reading just one chapter more. Thanks to Net Galley and Bantam Books for an ARC for an honest review.

I find it difficult to write a review on a thriller and not give away any of the twists and turns. I enjoyed the setting being in the Hamptons with a rich family and the large, beach home. As the book progressed some of the storyline might have gotten a bit far fetched and made me question some of storyline. The book did hold my attention and made for a fun, summer beach read which sometimes that makes for a perfect book for the moment in the readers life.

Thanks to NetGalley for an advanced copy of The Perfect Sister. #NetGalley #ThePerfectSister #StephanieDeCarolis

I really enjoyed this book! The setting in the glamorous Hamptons and the contrast between Alex’s ordinary life and the Blackwell family’s opulent world was fascinating. The way Alex uncovers the secrets hidden behind the facade of wealth and luxury kept me hooked. The twists and revelations were engaging, and the suspense built up perfectly as the story unfolded. It’s a gripping read for anyone who loves psychological thrillers with a touch of intrigue and hidden truths.

New to me author...but the story was a bit familiar. Murdered/missing woman's sister comes to town to figure it out. Of course there is a corrupt rich family! Lots of shady characters but you may not figure this one out!

Thank you Netgalley, the publisher and the author for the advanced reader's copy of this publication.
Mystery, drama it reads like a story gone bad. Not a five star read but more a three star. While I wont throw it under the bus I am not going to give it my high praise. I would pass on it but pick it up at a airport stand.

Sisters have a special bond, even when they are living apart from each other and have chosen different paths. Alex and Maddie are sisters who took care of each other as children when their mother was more concerned with becoming famous and their father left them alone. After their mother's death, Alex stayed in their hometown and got a job at a hardware store and Maddie left to fulfill her dream of medical school. One tradition the sisters had was to be together for their birthdays and when Maddie doesn't show up or even call on Alex's birthday she knows something is wrong. Maddie's last place of residence was living in the pool house of a mansion in the Hamptons and Alex is determined to find out where her sister is and why she hasn't contacted her.

I expected this book to be more exciting than it was; the many different viewpoints and flashbacks took away some the thrill factor for me. I also felt the story about the evil rich family and the bad seed children has been overdone and it wasn't until the very end that we received an interesting twist. There were also characters we didn't find out much about including Alex's boyfriend Ben who is mentioned but never a real part of the story. I did think the ending was exciting and think the author has promise in the mystery genre. Thank you to NetGalley and the publisher for a copy of this ARC in exchange for a review.

Alex and Maddie are two sisters, incredibly close, until the death of their mom. Maddie leaves after the funeral and after an argument with Alex. After Maddie promises to never let Alex spend a birthday alone, she doesn't call, despite their argument and Alex knows something is wrong. Alex goes to track Maddie down in the Hamptons with little information to go on. But she follows what breadcrumbs she has and she finds herself at the house of The Blackwells, an investment property owner who has shady secrets of his own.

While the concept of the book is good, it feels choppily written. I had to finish it to know how the whodunit played out. Consider it an easy beach read.

Thank you to Netgalley and the publisher for the ARC. Opinions are my own.
