Suspenseful with a surprising answer to "who did it". Heidi Perks wrote a good representation of mom's and their children.

A child is missing, which has to be the most absolute worse nightmare for a parent. Harriet, a helicopter mom, on a very rare occasion had entrusted her one and only friend, Charlotte, to take her 4-year-old daughter, Alice, along with Charlotte's three young rambunctious children to an outdoor school fair while she attends a bookkeeping class. After a stop at a concession stand for cotton candy, they head to the "Jungle Run," a large inflatable that stretched back to the very back edge of the field. As Charlotte and her daughter wait in the shade while the other three children take off towards the back to enter the run, she takes a minute to check her phone, her messages, texts, and Facebook. As her son and daughter slide down the end of the Jungle Run for the second time, Charlotte becomes panicked when Alice cannot be found.

The reader is hooked from the very first page as Charlotte Reynolds is being relentlessly interrogated by the police thirteen days after the abduction of Alice at the school fair. The book is basically divided into three parts--Now, Charlotte's Story, and Harriet's Story. Charlotte's Story is a combination of the police investigation and the more public perspective of the affected lives of Charlotte and Harriet. Once you get to Harriet's Story, be forewarned, the personal perspectives are even more in depth and revealing, and you will not want to put it down.

It is difficult to comment more without giving away any spoilers, but this book is definitely a must read. I am thankful for the opportunity from NetGalley to read an early release of this book in exchange for an honest review, and even more thankful for the three-year investment by the author and her editing team for producing an exceptional read.

Fantastic read. It really pulled you in from the the beginning and didn't let you go. It was a total surprise ending for me. Well written with excellently developed characters, it didn't want you to put it down. You NEED to read the book!I

*thank you to the author/publisher/Netgalley for the opportunity to read this book in exchange for for a fair and honest review*

This was a fast-paced psychological thriller that kept me quickly turning the pages to find out what happens next. It offered a fantastic twist!

When Charlotte's best friend Harriet knocks on the door and asks her to watch her daughter, Alice, for the day, she doesn't hesitate. Harriet never goes out and never leaves her child's side, so Charlotte is happy to take Alice along with her own children to the school fair for the day. What promises to be a fun day for the kids even if it's more of a hassle for Charlotte, turns into a nightmare. After Alice gets in line to go on a ride, she never reappears and can't be found anywhere on the fairgrounds. And Charlotte only looked at her phone for a minute (and checked Facebook)...

A fast-paced, original psychological thriller that will have readers quickly turning the pages to find out what happens next!

Harriet lets her daughter, Alice, visit a school fair with Charlotte and Charlotte’s three children. The first time she has let Alice accompany another adult, the child disappears.

The chapters alternate between points of view of the two women as well as between two time frames, “before” and “now”. Although a few things are a little too convenient in this psychological thriller, it is well written and engrossing. The author gives readers a lot to think about concerning friendship, jealousy, and guilt.

Thank you to Netgalley for allowing me to read an advanced copy of this novel.

Harriet was very protective of her daughter Alice, to the point that she has never allowed anyone else to watch her. When Alice was 4 years old, Harriet decided to sign up for a bookkeeping class and entrusted Alice with her only friend Charlotte. Charlotte was ecstatic about watching Alice as she has offered in the past. Charlotte has 3 children of her own so she decided to take the four children to the school fair. While at the fair the unthinkable happens...Alice goes missing. Was she kidnapped or simply wander away and get lost?

I loved everything about this book. Just when I thought I had the mystery figured out, another twist would happen and I wasn't sure how it was going to play out. I highly recommend this book to anyone that loves a good mystery.

I look forward to reading more from this author!

I think every mother can relate to this story. Many mothers have experienced a moment of panic, that sinking feeling in their stomach when suddenly that child that supposed to be standing next to them is nowhere to been seen. Luckily for us that most of the time this situation is resolved very quickly and doesn't turn into an ongoing nightmare with a bad ending. In this case the situation is even more complicated because the child that disappeared is not one of her own but her best friend she promised to take good care of her child for that day.
Add to the mix:
The constant interrogations by the police.
The accusing attitude of people, some of them used to be her friends.
A manipulating husband who is the father of the child lost and a lot of extra baggage from the past.
The clues are all through the book but I didn't expected how the book ended. The emotions and the events portrayed have a real live feel and you can't help feeling sympathetic or angry with the various characters. The book for me was very addictive so it was hard to stop reading when I needed to do other things.
The only reason I gave it a four instead of a solid five because occasionally I had a bit of a problem with the switching back and fourth between the two main characters Charlotte and Harriet. The present and the past. All by all I highly recommend this book.

Charlotte love her friend Alice's daughter and is overcome with guilt and shame when Alice's child disappears on her watch. And as one of Alice's few friends, Charlotte's negligence is all the more devastating. But as Alice and her husband work with the police to find their daughter, it becomes apparent that this disappearance is not how it appears. Told from both Charlotte and Alice's point of view, HER ONE MISTAKE is a fascinating page turner.

I felt earlier on that this book would be a bit predictable. At 25% into the book I felt I needed to put it down and take a break from it. I may re-visit and pick it up again to finish. I tend to crave more literary fiction or historical fiction when I choose a book, so this may be the reason Her One Mistake did not get my attention from the beginning.

This book is absolutely amazing! I read it in less than 12 hours because I couldn’t put it down. Such an amazing plot twist and excellent storyline.

Thank you to NetGalley for the opportunity to read this advanced reader copy. It was fantastic!!!

Received this free in exchange for an honest review. Thank you
This was a good fast passed thriller that will leave you guessing till the last minutes its over. At times I thought I knew where it was heading, but not until the very end.
Well written, not excessive filler. You got the feeling you were there and could see what was going on and what was really going on. I liked the story, but not sure if you could really pull off what happened, esp in England as I understand they have security everywhere
I will read more of this writer

This could definitely be a ripped from the headlines!
Her One Mistake by Heidi Perks is the phycological thriller of a woman whose husband is trying to run her crazy.
Who can she turn to for help?
Who will take the fall for the disappearance of her daughter?
This is definitely a 5 star read!

Her One Mistake is the latest story by Heidi Perks. Fair warning, the twists and turns in this story will make it impossible to put down. I sincerely wish I was able to give Her One Mistake more than 5 stars. This is the first book I've read by Ms Perks but certainly will not be the last. I was given an early copy to review.

Twisty thriller which keeps you guessing all the way through. The biggest twist is in the middle which turns the whole story back on itself. There are many revelations within the story which surprise and keep you moving along at a brisk pace. Totally recommend!

This book has so many twists and turns that I couldn’t put it down. I can’t imagjbe losing your friends child, what a nightmare ! This book took me on such a roller coaster and I enjoyed it very much.

My first by this author but certainly not my last .

I haven’t write a review yet for this book. But thoroughly enjoyed it! Thanks for he preview. I will certainly recommend it!

i would best describe this book for me as kind of like a slow burn. Meaning, it didn’t hook me right away, but kind of slowly drew me in. Part of me feels like it would be such an unlikely thing to happen, but part of me feels like things like this do happen.

At times I found myself so frustrated with Harriet, and just kept telling her to get a backbone! I felt awful for Charlotte, since who doesn’t every once in a while take a minute or two to check their social media, without something as horrifying as kidnapping happen! The twist was something you might think you see coming, but is different than what you expect!

Wow what a ride. As many twists and turns as you can handle! Kept me guessing until the end. One of the better books I’ve read lately. Well rotten with great flow. For me a book has to have good flow. And this one is great. Thanks NetGalley for the free digital copy of this book and thanks to the author and publisher as well. Really enjoyed reading this book.

Thanks to NetGalley for providing this review copy.

What more terrible thing could happen than to lose your best friend's child! Your own guilt at turning your head for a fraction of a second, your friend's grief and anger at losing her child. No friendship, now matter how great or how long could stand such a dire occurrence. Not only would everyone's opinion of you change, your own guilt would eat you alive. But if the whole event got suddenly turned upside down, how would you feel?

Reminded me of "Gone Girl" with such a sudden tornado of events right when you had everything figured out.

Great plot.
