I Know What I Saw
"A classic blend of I Know What You Did Last Summer and Carlisle’s unique storytelling prowess [...] Well written, perfectly paced, and crafted to the highest standard. Remember the name K. T. Carlisle. She is the one to watch." — Nicky Shearsby, Author of Beyond The Veil
"This thriller delivers on all levels—teen readers may very well devour this novel in one sitting." — Kirkus Reviews
A young girl attacked. An unbreakable pact. There’s more in the woods than meets the eye.
When 13-year-old Eliza Loft learns that high school senior, Renée Pope, was brutally attacked and killed, she’s horrified—and she just might be the only one who knows what happened. After all, Eliza was in the woods that night, and what she saw haunts her for years, especially since she can’t talk about it with anyone. Not when she knows deep down that a moment of mischief between friends might have been a contributing factor in Renée’s death.
But when an anonymous note claiming to know all about her involvement appears in Eliza’s locker years later, staying quiet about what happened may no longer be an option. After a co-conspirator with shared responsibility for the prank that led to Renée’s death receives an identical message and turns up dead just one day later, Eliza becomes even more panicked. Suddenly, she’s convinced that she’s being targeted for what she did and must fight to prove what happened before it’s too late.
A twisty, unpredictable thriller full of dynamic characters and dark secrets, I Know What I Saw is a gripping coming-of-age story that seamlessly blends elements of paranormal folklore and sasquatch mythology with all the conventions of a spellbinding whodunnit.

One gripping, twisty thriller full of teenage drama - the fights, rivalries, vivid imaginations, and the uncertainty of who saw what and whom to believe.
The author does a fantastic job: you start the story feeling like you know everything, only to have your assumptions challenged, and by the end, she wins - your guesses are completely lost.
Dark, atmospheric, and expertly crafted, it’s a story that keeps you guessing.

A sasquatch YA thriller set it the wilds of New York state? I'm there!
When I first saw the description of this book, I knew from the start that I had to read it. Vampires, werewolves, and ghosts have had their time to shine, and finally K.T. Carlisle give Bigfoot his time to shine. Believable characters and plenty of twists lead you to a fun read.

Wow! This YA thriller was a super fun ride. I've always thought cryptozoology was interesting, though I've never been big on Bigfoot. You don't have to be a Bigfoot fan to thoroughly enjoy this story, though! There are definitely hints of Pretty Little Liars and I Know What You Did Last Summer woven into the tale, and the immersive writing style kept me engaged and turning pages the whole time. I liked E a lot, and I felt her thoughts and actions were realistically portrayed for a teenage character. The book is chock full of red herrings and twists, so I'm genuinely shocked that my initial guess for the ending was actually correct! That almost never happens, and even though I solved the case early, Carlisle absolutely had me second-guessing myself throughout the whole book. Highly, highly, highly recommend this easy to read, well paced, small town thriller. I'll be checking out more from this author!

Fantastic and Engaging
The voice of this story is so clear and real. It did what a good book should do, it pulled me in and made me find little excuses here and there to open it and read with any spare second I could get away with!
K.T. paints such a great picture with her words that I felt zero confusion as to where I was in the story plot, world, or character's thoughts.
I only wish it was longer!

Eliza Loft is a teenager in a rural upstate New York community who witnessed a horrible crime. A classmate was horribly murdered in the woods…and a sasquatch may have done it!?
That’s not a spoiler. That’s how I KNOW WHAT I SAW starts. But where does it go? That may be a surprise–and it certainly is an interesting journey. Particularly when a mysterious note appears in Eliza’s locker, indicating that someone knows what she saw that night…and what she did.
The plot is a fast-moving one, with some nice twists. But Eliza is the heart of this book. Author K.T. Carlisle creates a complex, believable and likable central character. Eliza is hurting and confused. But she’s also resourceful and smart. Yes, this book is a thriller, but it’s also a YA story. Eliza used to be friends with Kate and Carissa, two of their school’s popular kids. But now, her only friend is Simon, a nice but awkward boy who is a true believer in cryptids. Her relationships and the main plot intertwine nicely over the course of the book.
Perhaps the best thing I can say about I KNOW WHAT I SAW is that it only took me four days to finish it. It drew me in and kept my attention–and I bet plenty of other readers will enjoy it too.

K.T. Carlisle has created a fabulously complex book dealing with a number of complex teen issues and how they affect children, including bullying, and teenage fantasies about their teachers, this beautifully crafted story explores the mystery behind the Sasquatch and is it possible that these legendary creatures live locally, or it’s something most sinister?
This YA Teen Fantasy is a wonderful story that follows Eliza, and her story and what can happen if you’re not careful.
A definite 5-stars story about Teenagers, Legends and much more.

This young adult mystery was a fun and intriguing read! So… is the Sasquatch real? Does it kill people? That’s the big question at the heart of this book, and I enjoyed unraveling the mystery as the story unfolded.
The suspense kept me turning pages, and the way the mystery was built up made it a great read. If you like stories with eerie small-town legends and a good puzzle to solve, this one is worth checking out!
Thanks to K.T. Carlisle for my copy.

Have you noticed everyone is talking about this book?
Well, there’s a good reason for that—it is everything you could want in a pacey YA read!
Eliza, or E as she prefers to be called (and not Eliza Loft) is an outcast at her school because of something that happened when she was 13 years old. She and her friends were in the woods on the night high school senior Renee was murdered, but only Eliza knows the truth about what really happened. Not that she could tell if she wanted to. They swore each other to secrecy.
Four years later, Eliza has done her best to move on from the incident. Sure, she’s bothered by horrible dreams, been ostracized by her old friends, and most people think she’s a liar, but at least she’s got Simon—the local Sasquatch believer and her co-host on their weekly podcast.
But when Eliza receives a note that claims to know her involvement in Renee’s death, and one of her old friends turns up murdered the same way as Renee, Eliza realizes her past is coming for her, and it might be trying to kill her.
As I said in my intro, this book has everything you want in a good YA read. I almost never read YA now that I am an adult, but I made an exception because I love this author.
The mystery is age-appropriate, and is delivered in a way that makes it believable that these kids couldn’t just go running to adults or police, which is not easy to do! I love the way it slowly unfolds, and how the original murder ties into the present-day killings.
But my favourite part? The characters! Oh my goodness, they are just the types of characters we need in YA. Eliza is an outcast, but is confident in who she is, and stands up for herself. I enjoyed reading about an outsider who doesn’t buy into the crap people say about her. She isn’t having the time of her life, but she realizes she’s still worthy of life and love. Sure, she shows moments of uncertainty and lapses in judgment, but that’s exactly what teenagers do.
I love her relationship with her dad—it’s full of honest love and the usual pull of a kid trying to assert their independence. It’s refreshing to have an involved parent figure, who stands by their kid no matter what. We also need more of this in YA.
Eliza and Simon are just too cute together as well. Their friendship feels very real, both in the way they are there for each other, and the things they hide from each other. And the will/they won’t/they pull in there is so adorable and again, perfectly age-appropriate. The confusion, desire, and anxiety are all written very accurately.
What about the Sasquatch angle, you ask me? Well, it’s not just a gimmick. Eliza and Simon hold a shared belief in the existence of the Sasquatch, and that belief, along with their podcast, and sighting messageboards play an integral part in the solving of the mystery. I love this angle to the story, and the creative avenue for the murder mystery as well as the uncertainty it casts in the true solution.
Did I manage to guess who it was? Yes. But not too early! And you know what, even if I guess I don’t really care as long as the reveal and conclusion are satisfying and this story ticks those boxes nicely!
The end made me very happy for a certain reason that I can’t say because of SPOILERS but let’s just say I hope Carlisle writes a sequel so I can see what Eliza and Simon are up to next.
That’s it! No notes! None, zip, no problems found, no little issues with plot or anything. FIVE STARS! READ IT NOW!

This is an incredibly well-written book. From the world-building to the characters, I was genuinely impressed. K.T. did a beautiful job of bringing Eliza to life. Her story is sad, raw, and deeply emotional. I would venture to guess that you could point to any American high school and find at least one Eliza in it.
That said, I did feel the central plot was a little lacking. The "big secret" Eliza carries didn’t quite live up to the emotional weight the story placed on it. While it doesn't paint her in the best light, it also doesn’t feel like something that would justify the level of near-constant panic and unrest she experiences. Guilt would be understandable, but the intensity of her turmoil didn’t fully land for me. Then again, that might just be how a teenage mind processes things. I'm not a teenager, so I’ll admit this may be a blind spot on my part.
Still, by the halfway point, I was hooked. The momentum picked up, and I just couldn't put the book down. The reveal at the end wasn’t entirely unexpected. It’s hinted at ahead of time, and I had my suspicions, but it was still a strong twist. While the pacing of the final chapters felt quick compared to the rest of the story, it made sense in context. When the truth comes out, it often does so fast, and life spirals just as quickly. I had the sense of “when it rains, it pours.”
So, I debated between 4 and 5 stars on this one, but ultimately, I have to give it 5. Even with my critiques, I'm still thinking about Eliza Loft. There are lingering questions, and I honestly hope there’s more to come from this character. I'd absolutely read more from this author, and I thank her for such an emotional and thought-provoking read.

YA novels are not something that I personally care to read, but there was enough intrigue here in the pages of K.T. Carlisle's mystery-thriller to get my attention, especially when it's premise is based around Sasquatch lore...
Carlisle is a magnetic talent. I keep finding authors choosing to use the 1st person POV, and despite finding enjoyment in a handful of these incredible novels, I do still despise it. However, their, and in this case particularly, Carlisle shines brightly to tell a teenage mystery with the nostalgic energy of a late 90s throwback horror minus the grisly gore...
Which is fine. That's certainly not a knock because I got lost in the story, forgetting I was reading a YA novel, and speedily turned the pages to discover each new teenage angsty twist. Admittedly, I solved the mystery early off a hunch, but I had to find out if I was right.
"I Know What I Saw," or rather, K.T. Carlisle's strong writing ability has me rethinking how slowly I read. I read this in 2 days, which I had the unrivaled amount of time to do, and enjoyed. The characters are relatable, perfectly captured and varied, and some even gave me sentiments of who could play the roles to a T. (I think pre-calculus could be taught by Glenn Powell in this world.)
If you want a fast-paced page turner, Carlisle doesn't disappoint. She completely engrosses you in this upstate, backwoods NY setting and the lore that lurks within its cozy little community, and, if you're not careful, just might be watching from the treeline.

I know What I Saw is a pleasant quick read, much akin to a chick-flick in the style of a whodunit. It contains all the necessary components that one might expect, the girl who once was cool, now being bullied at school, the widowed father, mean-girl clique, attractive teacher and dead bodies likely mauled by a roaming sasquatch.
The writing style is fit for the mid-teens to young adult range, and fits the typical genre of thriller fiction. The prose often feels like a writer attempting to write a book rather than a narrative flowing through the pages utilizing unnecessary descriptive or details that I found a bit distracting. The plot itself is sufficient enough to be engaging, and the pace does not lag in any deleterious way. Though for the brevity of the book this naturally comes at the cost of character depth.
Without going into spoilers, I did find the plot solutions hinge on rather convenient and contrived methods. And while many solutions I feel stretched believability, the questions raised were effectively answered, albeit not in a manner that I found myself saying, "well, I guess" rather than, "well done."
The story itself fits within the older thriller mysteries like a modernesque version of Nancy Drew or Goosebumps for YA readers who enjoy a mix of mystery, melodrama and a dash of the macabre.

Do you know what you saw?
I don’t believe in Bigfoot. However, that didn’t stop me from enjoying I Know What I Saw by K.T. Carlisle.
This thriller focuses on E, a teenager whose luck would give Peter Parker’s luck a run for its money. Luckily, Carlisle makes sure that E is such a likeable character, so you do root for her. Her best and only friend Simon is also very likeable, who could easily been a nerd stereotype but thankfully isn’t and his keen eye makes him probably my favourite character. The rest of the cast is equally well written with a lot of hidden depths and secrets, to again stop the obvious high school stereotypes.
There is plenty of suspense and the mystery is well done. Plenty of red herrings and clues, to keep you guessing; this is what a thriller and mystery should be. Also, is it wrong that I care about E’s old Beetle? No, it is not. It’s a sign of great writing.
The conclusion I’m in two minds about. On one hand, it seems a bit rushed with it being resolved in roughly ten pages. On the other hand, if it didn’t happen the way it did, it would have been unrealistic, and this is in a story about Bigfoot.
Overall, I Know What I Saw is a fantastic read and if you are looking for a thriller, this is one to go for.

I grew up with 80s and 90s horror paperbacks, with creature themes being a particular favourite of mine. This book jumped out to me because of this. I was thrilled as I worked through it to also pull out mid to late 90s teen horror movie vibes! Another nostalgic love I have.
Boxes nicely ticked, I settled into this instantly.
It's a wonderful YA horror thriller story with Eliza (E) a very compelling and likeable young lead character caught up in a disturbing incident, initially at high school, then later with further unsettling occurrences.
K.T. Carlisle internalises E's emotional responses to situations beautifully. It's so on point with this, with the descriptive and absorbing flow impressing me so much.
This is a very maturely written book and those (such as myself) who are way out of the range of being a young adult, can really enjoy it. This has a lot to do with its delightful retro vibes.
The mystery element to the various small town incidents are delivered in a cool noir style, and Carlisle's timings with the story beats are absolutely spot on. Everything is placed and unravelled at just the right time.
This is a tremendous book and it really should go on to be a cult classic.
I hear that a sequel is being worked on! Get in!

I Know What I saw has easily been added to my list of comfort books. It was such an enjoyable read, not only because of how well K.T. Carlisle nailed the depth of the characters and the very realistic high school drama, but also because this story felt like something I would have read ten or fifteen years ago. Not because of the drama, but because of the way it was written and the way it made me feel. I don't have anything against books that feel newer, but something about the nostalgia I got from I Know What I Saw is just unbeatable. Now for the story itself.... I loved the "relationship" between Eliza and her best friend, Simon. The struggles Eliza went through after the death of her mother are all too relatable as someone whose mom died at a young age. I Know What I Saw keeps you guessing at who is really responsible for the gruesome deaths of these girls. The ending is well played, I honestly didn't see it coming. I have loved every book I've read by this author thus far, and I can't wait to see what she comes out with next. Make sure you check this one out. You won't regret it!!

Carlisle expertly pulls the reader into the world of her characters in this absolute page-turner. I found myself saying "Okay, just one more chapter", addictively needing to know what would happen to the characters next, so much so, that I'm hoping there are spin-off books, or future explorations of this particular world. The characters were unique, but deeply grounded and relatable, and I found myself cheering for the protagonist because she desperately needed a win. The relationships in the book, friendships and otherwise, brought me immediately back to my high school days in the best way possible, and the big foot element kept me guessing and thoroughly intrigued throughout. I will absolutely be keeping up with everything this author releases. If you enjoy well-written mysteries, you will love this book.

Carlisle does a wonderful job of amping up the tension from page 1 of I KNOW WHAT I SAW and leaves the reader on the edge of their seat instantly. Her writing is impeccable and fluid, bringing the reader along on the journey with Eliza (or E), never taking you away from the action or E’s thoughts.
This is an easy and dreadfully delightful read and would appeal to anyone who loves fast-paced thrillers, action-packed stories, or creepy folklore. I, for one, love all three. Carlisle is an insanely talented writer whose work is immersive, descriptive, and she knows how to balance action and inner dialogue, which is something hard to find- especially in YA.
You should definitely pick up I KNOW WHAT I SAW else you’re missing out on the next bestseller.

Every now and then, you come across a writer who you just know is destined to be great, and K. T. Carlisle is one such writer. Her tone, pace, and structure help the words flow effortlessly from each page, her plotting ability creating a seamless blend of brilliance that means you lose all sense of time and space. I KNOW WHAT I SAW is a classic blend of ‘I Know what you did last summer’ and Carlisle’s unique storytelling prowess. I tore through this in just 2 days, which is not something I usually do. I just couldn’t put the book down. VERY well written, perfectly paced, and crafted to the highest standard. Remember the name K. T. Carlisle. She is the one to watch.

An exceptionally well crafted book
K.T. Carlisle has created a fabulously complex book dealing with a number of complex teen issues and how they affect children, including bullying, and teenage fantasies about their teachers, this beautifully crafted story explores the mystery behind the Sasquatch and is it possible that these legendary creatures live locally, or it’s something most sinister?
This YA Teen Fantasy is a wonderful story that follows Eliza, and her story and what can happen if you’re not careful.
A definite 5-stars story about Teenagers, Legends and much more.

I Know What I Read
I’m not a big YA fan, I don’t really care whether or not Bigfoot exists, and I’m not from a small town. Nothing about this book should have interested me. But I know what I read.
I read an attention-holding story with a satisfying plot and compelling characters, not the least of which is the town of Whitehall, NY. Carlisle made that little town come alive, so much so that on my next trip to New England, I want to walk its streets and explore its forests.
I Know What I Saw’s plot held together well and had enough twists to keep it interesting. All-in-all it was a very enjoyable read.

What an excellent book! The indie book world is awesome!
As a rather mysterious tale, I won't get into the details. A girl is sure she saw something, and it's ruined her life more or less. Every character was vivid and every scene compelled me to keep turning pages 'till the end and looking for clues every step of the way. The fact that agents didn't jump all over this when it came their way is just their loss.
While this is a rather fun and easy to read book, it is also quite a heavy one and I shudder to think of what specifics may have given Carlisle the insight to write it, but I'm glad she did.

Absolutely fantastical
Absolutely losing my mind over how much I loved this book! The characters are so cute, the set up is so classic, and the situation is extremely unique!
I know the initial intention of this book wasn’t romcom but it has very big romcom moments that are just, chefs kiss.
I had so many different theories about where this story was going to go, that I couldn’t wait to get to the end to figure out if I was right (I wasn’t)
10 out of 5 stars, can’t wait to read more from KT Carlisle!

Bigfoot fans, this young-adult thriller is for you. In a small town where Sasquatch sightings are a major tourist draw, there might be a worse monster lurking in the woods. Aside from that, this book paints a good picture of the secrets and anxieties teenagers carry as they navigate school, friendships, crushes, and grief. Add in the possibility of a crazed killer targeting young women and a couple of kids who start investigating the killings on their own because no one will believe them otherwise, and you have a surprisingly touching thrill-ride of a book.

This is a well written piece of literature. I enjoyed the book from the character development to the lay out and pace of the story.
Does this little town have a Bigfoot problem?
Seems someone has seen something disturbing.
Follow Eliza as she sorts through bad nightmares, mysterious warnings, and crazy conspiracies.
Who can she trust? Where can she turn?
I highly recommend this for a good read! 😁📖🪄

Well, K.T. Carlisle wowed me again.
Such an amazing book! I loved the Sasquatch element. So unique and gave a cool, wild element to the mystery. Eliza was such a wonderful, relatable character. She’s a very realistic teenager. This keeps you on the edge, wondering what exactly they saw. What is real and what is not.
Absolutely reading EVERYTHING by Carlisle.

A fun read that keeps you guessing!
This was such a well-written novel. I couldn't put it down! The story was engaging and all of the characters were fleshed out well. You could really feel how close Eliza and her dad were, and her will they/won't they friendship with Simon really makes the story fun. I had some suspicions, but didn't guess 'who done it' until late in the book. HIGHLY RECOMMEND!

A stunning story of teen drama, with hidden gems and shocks galore, this story is created with amazing depth of narrative that makes for an easy read, the story deals with the legendary Sasquatch, but it also has a few chills, thrills and surprises that make for a great adventure and book.
Exceptional storytelling and a 5-star story, definitely one author to keep your eyes on.

An enjoyable YA thriller.
Yes, it was predictable, but I’m a 40-year-old woman so I’m not the target demographic.
It was a quick, easy read, and though I knew what was coming, it was still interesting to see how exactly it would pan out.
I am looking forward to reading other books by Carlisle when I’m looking for a palette cleanser between adult books.

Unique Thriller
Very interesting storyline. Book is very well written and edit. Pace of the story was quick and flowed smoothly. Being from NY and having camped in this area I felt a connection to the characters.

An easy read that I think will be enjoyed by younger audiences but can be enjoyed by older readers too. I liked the main character and felt sympathy for her being bullied and all. The language is simple, and the story is engaging.

Kept me on the edge of my seat. I wanted to know what was going on! What really did she see in the woods? Was it really bigfoot, or something more sinister? This was the perfect read for spooky season.
