What a great read. I loved so much about this book. Petta (formerly Petal) is an obnoxious, pot smoking, commitment avoiding middle aged woman trying to be invisible in NYC and to forget her past that’s filled with the deaths of just about everyone she loved. That is until a random gynecologist tells her about a book she has to read. The book is dedicated to her and the author has named a murderous villain her name. She ends up back in Madison Wisconsin dealing with her ghosts while trying to figure out who wrote the book and what they have planned for her.

We find out what happened all those years ago throughout the book, while also reading chapters of the fictional book within the book.

I loved the premise but I also loved the writing, which was so much better crafted than the average mystery suspense. It’s at times very poetic and metaphorical, and at other times snarky and self deprecating.

Excerpt from when she’s finally bought this book with her name in it that keeps turning up everywhere that she doesn’t want anything to do with and has thrust it in the freezer:

I’d thought about leaving the book in there for eternity, letting it warp in the damp chill and become part of the lumps of frost that were taking over my small freezer compartment like tumors inside a body. Maybe I could hold out until a new bestseller knocked it off the shelves and it disappeared. My life would go back to being the same.

Could I deal with more of the same?

More barely surviving, more clawing through each day. I was running on fumes, and hadn’t realized it until the book crept into my life on little rat feet. My past had been feeding on me for years, leeching the nutrients from my blood until nothing but salty water ran through my veins. It was time to tie off my past once and for all, wrap a tourniquet around the place where the dead part of me met the living. Hopefully, whatever was left after the amputation could survive.

This was a fun romp by a new author and I’d happily read any more books she puts out.

I read a digital copy of this book via NetGalley. To be released summer of 2023.

I found the past year and coming into 2023, that I am reading and enjoying more mystery novels rather than romance as found I got bored of romance chick lit reads. This was a fun read and a bit of an I Know What You Did Last Summer type read crossed with Verity by Colleen Hoover. Almost thirty years ago, Petal lost everyone she loved when her parents killed themselves, and then her new best friend Megan died while they were in high school. After the tragedy happened, Jenny and Petal went their separate ways and never spoke to one another or about what happened that night their friend Megan died. Petal changed her name to Petta and moved on with her life, never looking back. Now years later, a new novel has been released and has also been picked up as a movie. The book talks about three friends who went out one day and only two came home. The dedication also reads "I know what you did Petal Woznewski". Petta is first told about the book by her gyno and then she sees it everywhere she goes. The name could be a coincidence but as she opens it and starts reading, tales of her life are fictionalised on the pages. Who is ME, Littleton? The other thing that strikes Petal as strange is that everyone else's names have been obscured except for hers, is someone trying to frame Petal for Megan's death after all these years? Now Petal, must head back to the hometown of Madison and discover who is behind the book and set the record straight of what happened the night Megan died. If you loved the 90s/2000s slasher films then you will feel right at home with Cayce Osborne's book "I Know What You Did".

4.5 stars, but rounding up because this was really really good. I love stories about a book inside a book, and this one was so intriguing and twisty and engaging. I stayed up way too late to finish this up, but no way could I find a stopping point once I was to the half-way mark. Ahh, the suffering I gladly endure in pursuit of my reading passion. I had no idea what was going on, what was real, who was real, who the bad guy was. Everyone was suspected at one point or another in my Scooby Doo mind, so I guess that means I "technically" figured it out. If you read a bunch of thrillers, I think you'll find this one of good ones that stands out a bit from the rest.

A decent four star mystery/crime novel with an interesting main character. The story kept me intrigued all the way through but I especially liked the use of humour around a quarter of the way in, which elevated the entertainment value for me as a reader. This lasted for a little while but didn't follow through to the end.

I liked the author's use of metaphors and similes which were very creative. But I felt the references to movie plots were overdone as I got a bit tired of them. I was very pleased the author did not make use of an unreliable narrator as this is a pet peeve of mine.

I was beginning to think that the final reveal was going to be a cliche ending but was pleased to find that this was not the case. I feel this will be an author to watch and I will be interested to keep an eye out for her next book.

I received this arc from netgalley in exchange for my honest review.

"But that was before the book began to stalk me. I know that sounds crazy paranoid, but it’s true."

Petal, or as she likes to be called Petta, learns a dark story from her teen years has been spilled. In fact, it's on the New York Times bestseller list--a published book by an anonymous author using a pen name. Only three people know of what happened that night. Petal, her ex friend Jenny, and Megan who is now deceased. But bits and pieces aren't adding up and many different culprits pop up from Petta's past as she desperately tries to uncover the origins if this story she hoped would remain buried.

This was captivating, addicting. I couldn't put it down. There some great and shocking twists. I couldn't decide who was behind the book until the every end it was revealed. I loved the excerpts from the book too. Excellent thriller.

This had a really original premise so I was exctied to see how it'd all pan out
The plot was a bit slow paced but it was certainly creative how everything was set up! Not terribly logical but creative. The main character does seem to exist mainly around her drug habit which featured strangely prominently throughout and its not the best image of a weed smoker but each to their own really. The ending is quite predictable just because who else could or would it be?! I'm also not convinced you can stop a murdering psychopath by doing what Petal did.... but.... it is fiction so whatever. This feels really critical but it is a well written book, and it is a completely original take on the "childhood secret forced someone to return to hometown where someone else tries to murder them" type book. I did enjoy it aside from the above little things that annoyed me but I'm sure plenty others won't think twice about them

This book kept my attention beginning to end. Loved it! The characters were well developed. The book kept me engaged and wanting to know what would happen. A bit slow at times, but overall I would recommend.

What would you do if someone wrote a book blaming you for a death that happened in your past - and used your full name to do so?

This book was exactly what I hope for when I pick up a thriller. The tension kept building. The new reveals didn't fully eliminate all the suspects. The clues were all there so the reveal at the end wasn't out of left field - but it also wasn't super obvious from the start. I started this after wishing everyone happy new year and didn't put it down until I finished it at 3am. It isn't the fastest paced thriller, but it was an enjoyable ride and I was never bored.

Petta (Petal)'s life is a bit of a disaster - she hides out in her little NYC apartment, eats junk food for breakfast, and generally doesn't have the most stable life. However, it's exactly the way she needs it to be for her to feel safe. She's snarky and I enjoyed her commentary throughout the book. When someone publishes a book that names her - with her full name - as her friend's murderer, she goes back to her hometown to find out who is framing her and clear her name.

Thank you to NetGalley and Crooked Lane Books for the opportunity to review this book ahead of publication. This does not affect my opinion regarding the book.

When Petta starts hearing about a best selling book with the main character sharing her unique name she tries to disengage herself. As the book seems to be haunting her she reluctantly starts to read. The similarities to her high school days have her questioning who wrote the book, and why.

This was a twisty suspenseful book that had me guessing the whole time! While I enjoyed the book I felt like it was missing something and that the suspect list was short. I did love the surprise ending to the book within this book “No one suspected”. This read kept me on my toes.

Thank you NetGalley for the early access in return of an honest review!

bleh, this book was ok. it was kind of boring, and it kind of just kept going on and on. i was gonna dnf it but stuck it out until the end, go me !
the main character was so boring and her entire personality seemed to revolve around smoking weed, eating food, having a FWB who she ghosts constantly, and having dead parents lol. none of the characters had any depth, which im not a fan of.
2.5 stars rounded to 2.

Cayce Osborne’s debut novel is a fabulous suspense thriller featuring Petal/Petta, a character with flaws and issues just like the rest of us. She’s not a lovable, beige character and I love that about her. Cayce has written her brilliantly, her voice is unique among a plethora of books that have main characters with little or no substance, so unrelatable and one-note. Petta has depth and colour in abundance.

I Know What You Did had this self-appointed-crime-solving ‘expert’ guessing incorrectly at every turn. And I loved that I didn’t guess the ending… ‘Who wrote the best-selling novel?’ ‘What really happened to Megan?’ These questions kept me eagerly turning the pages and desperately trying to stay awake to finish the book to discover the answers.

The story within a story was very clever and really well done. The ‘authors’ voice was very distinct from Petal’s and made the distinction between the 2 stories easy to follow.

I hope Cayce is currently writing her next book because this reader is definitely eager to get her hands on it.

Thanks to NetGalley and Crooked Lane books for the arc in exchange for an honest review,

Petta Woznewski receives a book from her boyfriend, Gus, which purports to tell the story of an incident from her high school years which she has kept secret. Only her friend, Jenny, knows about it and she has kept it secret as well. But now it is out there for the world to read about and the book doesn't tell the truth about the secret. Petta has to find out who wrote the book and set the record straight.
I didn't like Petta much throughout the book. She was so angry and engaged in self-destructive behaviour. The story is told from her first person point of view so we don't get a break from her pessimism. Gus seems like a really decent guy and I wondered why he stayed with her.
Osbourne is a good writer and, given that this is her debut novel, I can see her getting better in the future. I will watch for more of her writing.
Thank you to Netgalley and Crooked Lane Books for an ARC of this book. The opinions in this review are mine and I was not compensated for them.

Petal (Petta) is content with her quiet life in New York, until she becomes the subject of a novel. Her full name is mentioned in the novel and the author seems to have included details that only her closest friends from her school days knew. It includes a dark secret she has buried for all those years. In attempting to find the author behind the pen name, she returns to her hometown and things really start to get interesting.

I enjoyed the secrets and the dark past entwined through this one and there were some interesting twists. I definitely would not have guessed that this was a debut.

Thanks to NetGalley and Crooked Lane Books for this gifted review copy.

So you are 44 and perhaps not thrilled with your life in New York City , but you are settled in and content with all of your dysfunctions. Then the title page of a best selling murder novel is dedicated to you and "what you did". Petal Woznewski feels compelled to go back to her childhood home of Madison, Wisconsin , and face one of the traumas that shaped her. The book was uncanny in some of the knowledge of their 14 year old selves, but Megan hadn't been murdered and only she and Jenny remained that knew the whole story. So who was behind this book and why had they changed everything but her name. This is definitely worth your time .

Also must say I hardly ever highlight passages of a book. The last paragraph of this book struck me- check it out.


Thanks to NetGalley, Caye Osborne, and Crooked Lane Books for the opportunity to read this book in exchange for an honest review.

Strong thriller from an author I didn't know anything about. The writing was good and the narrative was very catchy. I love it!

Was so excited for this read. The title and cover looked like my kind of thriller and it did not disappoint one bit. This book was captivating from page 1. And it almost read like a true crime novel which made me dive deeper into it. Although it doesn’t come out til 2023, it’s by far one of my favorite 2022 books!

Thank you to #NetGalley, Crooked Lane Books and Cacey Osborne for the opportunity to read an advance copy of I KNOW WHAT YOU DID, to be published 18 Jul 2023. An excellent book from a debut author! The characters were real and believable; the plot was intriguing; the level of suspense moved the book along quite well. The protagonist was an independent woman living in New York City. She had high ideas about that level of autonomy and worked at maintaining them. When she accidentally discovers a book with her unusual name as one of the characters, she reluctantly sets out on a mission to determine the source. Individuals who enjoy the writings of Lisa Regan and Shari Lapena will likely enjoy this novel. #NetGalley #CrookedLaneBooks #CayceOsborne. #IKnowWhatYouDid

This was the first book I have read by Cayce Osborne and I can tell you it will not be my last. Petal Woznewski is a loner living in NYC when she hears about a new book that just came out featuring her as the main character. The book is set to be fiction but it has a LOT of information about a past Petal wanted to remained buried forever. The only way to get to the bottom of this is to go back to the source of the issue and figure out who the author is of this book and find out who wants to revel her secrets that she wants left alone.

This book floats between Petal's current life and situation with chapters of the "book". You get little snippets along the way that keep you wanting to turn the page. Petal gets threatened and tormented as she is trying to uncover the truth about the author. Someone wants her to pay for things that she did in her past. But does the book have it right? Did Petal do the terrible things that it claims she did and does she need to atone for her mistakes?

This is a must read for people that love thrillers/mystery type novels. This book is such a great quick read and I will be reading more from this author. Thank you NetGalley and Crooked Lane books for an ARC of this book in return for an honest review!

Even if the plot reminded one of the classic domestic thriller with secrets from the past this book was very original as it's a sort of meta book and the Petal is an interesting character as she's not likeable but you cannot help liking her.
There's plenty of twists and I didn't expect the solution.
It's a good debut, recommended.
Many thanks to the publisher for this arc, all opinions are mine

I was very unsure of this book at the beginning. It took a coupld of chapters to get really pulled in but it did happen and I finished this book in a little over a day. The twist at the end was unexpected but not the dramatic, thrilling ending I was hoping for.

With all that being said, I really did not like the main character. For a middle aged woman, I found her extrmemely obnoxious and childish. Some of that was because of the childhood trauma she suffered but it was over done and made her very unrelatable. It became her whole personality adn the only way she could cope was by "smoking a bowl" or being a slob, The over use of movie quotes and song references really did not add to the story. While I did enjoy the book for the most part, I am not sure I would read a book by this author again, if that becomes a habit with her main characters.
