Dawn Foster is the new girl at Sierton High. Being new and cute, she easily makes friends, and joins the cheerleading squad. At her first party with the "in" crowd, the most popular girl in the school dies. However, as the death is investigated more, all of the "it" crowd become suspects in the death. As the investigation continues it is clear that there is more to this story than meets the eye.

I appreciated this book, and thought the twist at the end would be great, however, I believe there was a writing error that caused a fair amount of confusion at the end. The book explains that Dawn did not move away, but then explained her moving back... so not sure how to interpret that. That being said I appreciated where the writer wanted to go with this novel, and I would have appreciated the reveal and twist at the end had the writing been more clear.

I'd like to thank Netgalley and Sourcebooks Fire for providing this ARC in exchange for an honest review.

I had a hard time getting into this. I'm giving it a 3 because I did like the twist on the end.

I loveddd this book. This is Mean Girls meets Pretty Little Liars and I’m here for it. I didn’t see the twist coming which is always a big plus for thrillers

When the mean girl of a high school, Ella, is murdered, Dawn becomes the number one suspect. She refuses to be blamed for something she did not do though and starts looking into Ella's past to find the true culprit.

I wanted to like this one, but I just could not get into the characters. It also has a lot of sensitive content, so I'd advise readers to be wary of that.

I had this really weird craving for a thriller and I couldn’t get rid of it. Out of nowhere i thought this might be the one to do it. And so I gave it a shot. And then I fell in love. That’s it. That’s the review. If only, if only I could write this and leave it that way lol

Ok so this one was actually really good. It’s been a really long time since I’ve read a book with an unreliable narrator that wasn’t like on drugs or drinking. This one had an interesting twist tho. The narrator was unreliable, but we didn’t actually know it until the end. And this is the freaky part lol Because I remember wondering why the hell she was so invested. I was like I’d leave them bitches right there. I don’t want to cheer THAT much. But the more I read, the more it made sense. And I was flabbergasted lol There’s no other word to explain it. I remember having to message a friend of mine so I could be like WTF because this shit legit caught me off guard. I can truthfully say I never saw this coming. And I can’t wait to see more people with reviews see if I was the only one who had no idea.

This book also deals wit some bigger topics as well. Bullying is a large part of this and I will gladly recommend this to people because they think it’s over now. Bullying is unfortunately still alive and well. And I also liked the way there’s numerous people who were the victims of the bullying, including their friends. (I mean not that I enjoyed it, but I liked the way that it was so realistic. Bullies are mean all the time and they’re even like that to their friends. ) People are quick to say it’s not what’s happening or that that person doesn’t mean it like that, but I this is a good way to look at and recognize that it IS like that. Another big topic this deals with is fatphobia and eating disorders, so please be kind to yourself if these are one of your triggers. Mental illness is also present, but it’s never given an exact name.

I really wish I could have seen my face once I finished this book. I know I was like wtf with my eyes wide open lol It was so outta there. And even though most times I hate when I don’t get all the details from the beginning, but this time I think it was warranted. I had my eye on someone else, but that was like the biggest red herring of all time. And I cannot wait to get my hands on the next book this author writes.

What originally drew me in to this book was the cover. Yeah it’s just a plain solo cup, but I think it was the Queen B of the school aspect that pushed it over for me. This book was so good! I couldn’t tell anyone about it, but you can bet I will be screaming it from the rooftop when I can. And you can bet I’m going to put it on all the book recs I can when people ask for a thriller or something lol

Thoroughly enjoyed this, great fast-paced YA mystery that wasn't predicable ! Can't wait to recommend this to borrowers

This is an absolutely riveting ya thriller that will keep you on the edge of your seat and gasping with each twist and turn!

Dawn Foster just transferred to Sierton High School from Santa Cruz, she's recovering from a horrific car accident that left her father disfigured, her mother paralyzed, and everyone needing to move in with her aunt. In an effort to prove to everyone she's doing okay Dawn tries out for the cheerleading squad where she falls in with the popular crowd. At a party one day the schools queen bee, Ella, is murdered and all eyes are on the popular clique, Dawn included. Someone at the party must have done it, but who? Between bullying, cattiness, backstabbing, and sleeping around, there's more than enough people who would have a good reason for wanting Ella dead, and all of them are willing to implicate Dawn. Dawn is determined to uncover all the secrets, to clear her name, and to keep this from happening again... At all costs.

OH MY GOODNESS.

I was hooked on this one from the very beginning and couldn't believe where I ended up by the end of the book! All im going to say is this- if you think you know what's going on, you don't. This book felt very reminiscent of many YA mystery thriller books at first and as a regular reader of the genre, I was so confident I had this one figured out really early on and boy am I happy to say that instead Cindy R.X. He took me on such a rollercoaster I couldn't be any happier that I didn't guess what was actually happening!

This book was twisty, exciting, engaging, and so smart! If you enjoy phycological thrillers that are fast paced and play out like an excellent movie or mini series in your head, this one is for you!!

Fair warning- it is YA but comes with some pretty hefty content warnings. Bullying, mental illness, eating disorder, and suicide are the most prevalent. I would only recommend this one to upper YA readers and more mature audiences!

Perfect Little Monsters is a rollercoaster ride of a YA thriller, full of vivid characters, surprising turns, and a bit of dark humor. A modern-day Heathers that will appeal to anyone who likes reading stories about revenge, jealousy, or popular girls with dark secrets.

Perfect Little Monsters kept me guessing the whole time. It's a story that begins with deadly hide and seek, that has dangerous car accidents, and plenty of flashbacks. It's a book with red herrings, false starts, and plenty of screams. If you are looking for a summer read that will completely devour you, obsess your free time, and keep you up late, this is for you!

Dawn is new to town. She makes friends with the "in" crowd, but it doesn't last for long. When Ella is murdered, everyone becomes a suspect-especially the new girl with secrets. Perfect Little Monsters opens with a strong first chapter that will pull you in. The rest of the book does not disappoint! I am very excited to add this to our library collection and will definitely recommend this to my high school students next year.

I'm not a big reader of YA books, so maybe my opinion is influenced by that fact. The first three quarters of the book I enjoyed until the big twist. I thought the author depicted bullying really well, the author being a victim of it when she was in school. The police questioning the students without parents present was just not realistic. And not to be picky, but the fire building scene at the end was inaccurate. But my main problem was how the mental health/behavior of the main character was depicted. The message that bullying is bad got lost and overshadowed by even worse behavior. I would have preferred a more educative resolution.

Ella, the most popular girl in highschool was murdered and the new girl, Dawn Foster, is the main person of interest. As Dawn tries to clear her name, we uncover the secrets of Ella's friend group and the people who have been wronged by her. This book was a good read and wanting to kept me going. It was twisty and you weren't sure who would be the killer. At the end, it was a shocking finale but the reasoning behind it, in my opinion wasn't the best motivator.

Perfect Little Monsters by Cindy R.X. He- Tense and exciting, this YA thriller/mystery was totally satisfying. I was surprised by the twist and was so sad once this book was over. I really felt for these characters and related to Dawn’s determination. This was a great read!

Perfect Little Monsters is a fast-paced, easy read but don't let that fool you. . . because it has the wildest twists and turns! This was a fast-paced, heart-pounding YA thriller that had me furiously flipping the page. Reminded me of pretty little liars or You with the school setting. A great book!

“Someone has murdered the queen bee of Sierton High School. All the dead girl’s friends are suspects. And each one has a reason for wanting her to die.”

Wow this was such a good and twisty debut young adult thriller! Such an engaging read! Gives Mean Girls with murder vibes!

It was very well written with an intriguing plot and excellent pacing! Tons of suspense and tension- I did not want to put it down! And I really liked the dual timeline.

This one also has a lot of depth to it as well as it touches on some serious topics around bullying and suicide- really shines a light on the cruelty of bullying and the dark impact it can have.

I still can’t believe this was the author’s debut! Cannot wait to read her future works. Highly recommend reading this one!!🖤

These books are meant to keep us up reading— and for this story, I can confirm this is so true!

Dawn transfers schools in her senior year, which is tough — but she’s able to fit in fairly well among the cheerleaders.

Until their captain dies, and now they have a murder investigation on their hands.

Dawn wants to solve the murder so no one innocent goes to prison - but maybe these cheerleaders aren’t so innocent after all…

This book is like a psychological thriller meets Mean Girls, and it’s done perfectly.

I don’t want to spoil anything, so I’ll say this: I had no idea what was coming. And now that the book is closed, I can’t stop thinking about what happened!

Seriously, my mind is that Charlie Day meme right now with the board and the string. In the best way possible!

My advice is if you like a thriller, and you want a book that’s extremely well written and will keep you utterly hooked, pick this up and just let our author guide you down a very, very surprising path.

I see this author becoming a staple in the genre, folks. I give my highest recommendation!

Of course, check tws ❤️

What a fun addictive twisty thriller! Excellent for a debut. I'm all here for the Mean Girls vibes and fast-paced short chapters. Highly recommend to thriller fans!

This is a lovely little thriller. It is gorgeously twisted and I devoured it in a day when I was supposed to be doing something else!

This gave me a little teenage angst even though I am now an old crone. I guess we never forget. I love the twists and the mystery in this one. It was weird and I like weird.

Perfect Little Monsters is the perfect YA suspense thriller! It's fast-paced and heart-pounding, packed with jaw-dropping twists! There are trigger warnings in this book, one primarily being suicide. We follow two timelines, one being Hannah's and the other, Dawn's. Dawn has relocated from California to Wisconsin and is now a senior at Sierton High. She, like most other teenagers, just wants to fit in. She joins the cheerleading team and starts to make friends, however, she quickly sees her friends' true colors.
Dawn, on the other hand, although she tried to make friends at Sierton High, she was not as lucky. Instead, she was terribly bullied, leading to her multiple suicide attempts.
The twists and revelations in this book were so insane and mind-blowing, and it all started unraveling after the death of one of the students (and most cruel and unkind member of the cheerleading squad). This book is a page-turner for sure, and one that will definitely leave you on the edge of your seat! 4.5 stars!

Thank you NetGalley, Sourcebooks Fire, and Cindy R.X. He for such a compelling ARC!
