If you love a book with lots of mystery and suspense then this is the one for you. There are so many hints dropped at the start of the story that make you want to keep reading. Why did Grace and her dad leave London and move to a quiet village in Devon? Where did the Echo device in the farm house they're renting come from and who programmed it to make threats in the middle of the night? And were the sudden spate of "accidental" deaths in the village over the past couple of months really all accidents? The last two questions are ones that Grace sets out to solve using scientific methods. But Grace's problems from London follow her to Devon and make her mission to find the truth much more difficult. Will anyone believe her theories?
I love a story where I am desperate to find out the answers. This one has a big twist at the end that is very cleverly done as I thought at one point that I'd spotted it, but then second guessed myself. I absolutely loved this book and would definitely recommend it to older teens.

An entertaining YA thriller, though the strategic withholding of information leads to a rather frustrating reading experience. I can see this book being an instant hit with some readers, while others will find fault. Thanks to NetGalley for giving me the opportunity to read and review it before publication.
Our main character Grace has moved with her dad to a sleepy Devonshire village. Rather stereotypically people are not the most amenable, but when Grace starts hearing threatening messages coming from the Echo installed in their home her investigations rub a number of people up the wrong way.
Without giving important plot details away there are a high number of accidental deaths in the village. Grace is convinced that someone is behind these deaths so she conducts her own murder investigation. Suffice to say, she’s onto something but the continual allusions to her past - without telling us of its relevance - made a rather unsatisfying experience.

Have you ever had to relocate your life? Have you struggled to move on from past events? Have you become obsessed with something that has nothing to do with you? Gracie has and this is her story. She's moved to a new location far away from her old life and she falls into researching recent deaths in 'the safest village'. Unfortunately, this research doesn't go without problems and Gracie eventually realises what happened to make them move away.
The whole way through, I was guessing who the murderer was and several times I was convinced I'd got it. I never did! There so many twists and turns that I didn't see them coming. The final reveal at the end was both terrifying and heartbreaking. This is a great read for anyone who loves a murder mystery.

Grace moves to the country in Devon with her dad. They have moved for a fresh start after Grace suffered some (unspecified) trouble. They have an ex-service dog called Shelby who has also undergone a trauma of her own. The village is very quiet, too quiet for Grace but it seems that may not be the whole truth. One night Grace is downstairs having trouble sleeping when the smart speaker (Alexa) in their rented house suddenly switches on & tells her "I'm going to murder you."

When it happens again the next night, Grace realises the speaker has been pre-programmed & that the threat was aimed at one of its previous owners. When she starts to investigate, Grace uncovers four mysterious accidental deaths linked to the device. Her dad won't believe her so Grace treats the deaths like a science experiment, gathering evidence & testing her hypothesis that one of the deaths was in fact a murder.

Unfortunately this didn't quite live up to the early promise for me. It deals with mental health, trauma, & PTSD not only for the main character but for little Shelby too. The mystery itself wasn't bad (although the twist was pretty obvious) but the main character was a problem. Basically she is annoying as hell. Would all these adults really spill their guts to a nosy 16-year-old who just arrived in the village? No, they'd tell her to take a hike. Shelby is an absolute sweetheart though so I'm going to up the rating to 3 stars just for her.

My thanks to NetGalley & publishers, HarperCollins UK Childrens'/Harper Fire, for the opportunity to read an ARC.

I love Sarah WIshart's books so this one really excited me, I really got into this book and loved working out the mystery of the town and it kept me hooked.

I received an E Arc copy in exchange for an honest review.
I was quite surprised with this YA title, I know that YA can be a really gritty genre but I found this so dark that I genuinely struggled to finish this. No spoilers, but the plot was very twisty but I found distressing. The themes of mental health were sensitively handled, but again were difficult to read, I struggled to stick with a young person making choices to help them self destruct. I also found the material about the abused dog extremely distressing.
I actually guessed the ending, although I think it was pure luck. It was a well constructed and twisty plot.

I've always been a bit nervous of my Alexa, and this book hasn't helped. A clever mystery, I was pleased with the ending and thought it was an engaging read, but the main character Grace was almost completely ruined it because of how annoying she was. A shame, because otherwise this would have been an excellent read!

The gist of the book: Grace and her dad decide to leave the hustle of London behind and settle in a quiet village in Devon for a new beginning. Not long after they unpack in their rented home, Grace finds herself in the kitchen late at night, grabbing a snack, when their old Echo suddenly turns on and delivers a chilling death threat.

This book wasn't it for me as the writing felt stilted and it felt like the reader was constantly told that there was something about Grace's past that they weren't privy to (which when you reach the end you understand but was frustrating as a reader and felt very drawn out). Even when you find out about Grace's past and why she had to move the climax felt short.

The reveal of the murderer as well felt flat as it introduces an element to the group of suspects that you only find out through the MC themselfves - meaning you as a reader cannot figure it out until they do which feels deceitful.

I will try to be honest and clear on the reasons why I didn't liked this book while being part of the "targeted audience" (I really love YA murder mystery!).

First of all, there is 2 tropes I really dislike in any mystery/thrillers I'm reading, may it be adult or YA, which are:
1) the "there were something really important happening before the beginning of this book but while we'll mention it a lot of times you won't get any explanation before the very end of the book" trope. Okay, while I've finally read the explanation in the very last chapter before epilogue (yes!), I do get the reason why it has been used. But still, it's frustrating as a reader.
2) hidden identity. It totally leaves us reader outside of the guessing who did it, you can try and guess the guilty characters because you have no possibilty to guess at that hidden identity until brought by the MC herself...
I know it's personal but it really didn't helped me appreciate the book.

I really didn't liked Grace. She's selfish, manipulativ, reckless, and let's be honest stupid while herself saying she's an adult and a scientist (she's 16 years old let's stop with that "we scientist we do that" please). The way she's investigation is really reckless, too direct, and she's obsessed. You get to understand that obsession with her past (yet here again we get it at the end, so you spend the whole book disliking her obsession), but it's still very frustrating and unpleasant. She's hurting everyone around herself (and herself) without much realizing it, or at least with little care about it.

I only liked the idea of all the investigations and searching for which accident was truly an accident and which one was actually a murder. The results and explanations were interesting (while being easily given away when confronted). I also really appreciated Shelby and Jem, and I wanted to give my support to Gracie's dad.

Grace and her father move from London to a sleepy Devon village in search of a fresh start. Soon after they move into their rented house, Grace is having a midnight snack in the kitchen when the second-hand Echo springs into life and makes a mysterious death threat.
Science-obsessed Grace decides to investigate and some comes to the conclusion that one of the spate of recent accidental deaths in the village is In reality a murder. She uses her scientific methods to identify the victim and the murderer. Her persistence cause ripples throughout the village but she is determined to solve the mystery.
This YA mystery thriller will appeal to it’s target audience with its mix of drama, romance, suspense and mystery. The venn diagrams scattered through the book give it an unusual STEM element, the many twists and dead ends keep the reader guessing and Grace is a very likeable main character. Some important topics are subtly included and sensitively handled which added more depth to the story.

A YA crime / murder mystery with lots of twists and turns. Grace moves away from London to start afresh in Devon after something traumatic happened to her. When she arrives, she realises that the death rate in this sleepy town is way above national average. When her Alexa starts to make threats, she sets out determined to prove that something out of the ordinary is going on. I must admit, that I'd worked out the twist by the end but that didn't stop me from enjoying it. MY students will love this book.

Thank you to net gallery and the publisher for this arc copy. This was so much fun to read, I really liked Grace as a character. I was hooked from the start of the book to the very end. Tthe elements made it a fun, engaging suspense murder mystery book. It was such a joy of a book to read. I liked Grace and how she figured out the murder. Grace has a brilliant mind and knows how to use it. This book is very modern and I think it will appeal to all ages from the age of 13 plus. It’s a very well written book and I can’t wait to read more by this author xxx

This was so much fun, I really enjoyed Grace as a character. I was hooked from the start, the elements made it a fun, engaging suspense murder mystery.

I like this one too as the plot is very original and creative. Its target readers will probably love it, I have to say though that I much prefer the author's previous work which I also previewed on Netgalley, "Four Good Liars" -- a book I will be using in one of my courses.

What a joy this book was to read.

I loved Grace and how she unearthed the murder, She has a brilliant mind.

This book is very modern and I think it will appeal to all ages. It is well written and with the fabulous characterisation and well developed plot it is a book that I will re read and recommend

I am still absolutely REELING after finishing this book and it completely had me in a chokehold.

I was addicted from the very start and it had no problem at hooking me whatsoever. This book had all the elements within to make it an absolutely amazing detective YA, suspense murder mystery. I don’t think I could have loved it more if I tried.

First off, Grace was an amazing character to follow and her insights and perspectives made the book so so interesting. You can feel the vibes are off and everything deliciously begins to come together as you read on. She’s a credit to STEM and her methodical investigation of the cases were remarkable. Shelby, her little anxious dog too also had my heart.

Grace and her dad (+ adorable dog) escape to a seemingly quiet village with one of the lowest reported crime rates in the country. She’s escaping London with hopes to start anew. But quickly sees that the spate of unexplained deaths may not quite be as innocent as they seem but when she begins asking questions, she starts to ruffle more than a few feathers…

As a woman in STEM I really loved Grace’s approach. The whole book felt so novel, engaging, exciting and addicting. I really couldn’t put it down and annilihated 300 pages in one day. No regrets. It was so so good!
