One body. Five suspects. Total darkness.
A tense, claustrophobic historical mystery set almost entirely underground at the onset of the Great Depression about the discovery of a 150-foot waterfall in the middle of a mountain, the unthinkable crime that happens in its caves, and a woman who’s never felt more alive.
In 1928, a Chattanooga man disappears down a hole in the ground and discovers a 150-foot waterfall in the middle of a mountain that he names after his Ruby Falls. Within months, visitors can buy tickets to see the falls for themselves. Ada Smith has been sneaking into the caves at night, entranced by the natural wonders around her and the freedom granted by this new underground world.
But it’s tough timing for a natural wonder. As the country flounders in the Great Depression, a shrewd public relations ploy seems like the only way to save Ruby Falls. A famous mind reader and mystic agrees to launch himself into the Ruby Falls caverns where he will attempt to locate a hidden hatpin using only his psychic abilities. He'll be joined by five his manager, his wife, a guide, a Chattanooga businessman, and a reporter from the Chicago Times. But they’re not alone in the caverns. Ada and another guide, Quinton, have been asked to follow the mind reader’s party at a distance, staying out of sight. They are a safety net, in case of a broken leg or busted flashlights.
One of them will be dead before the end of the day.
Faced with a corpse and the stark reality that one of the people in her midst is a killer, Ada needs to get everyone—the murderer and the innocents—back aboveground before their light runs out.
Ruby Falls is both a unique twist on the locked-room mystery and an exploration of loss and what it means to start over. It’s a heart-racing story of survival and a testament to the threads that bind strangers together. Set against the true story of the discovery of Ruby Falls, the novel also draws on the memoirs of Katie Stabler, a female guide at Wind Caves in South Dakota.

Review of advance copy received from Netgalley
Ruby Falls is a 150 foot waterfall located in the middle of a mountain. It was discovered by Leo Lambert in 1928 and he named it after his wife, Ruby. It was opened up for tours via an elevator at the start of the Great Depression. Ruby Falls by Gin Phillips is inspired by that story and adds a locked room mystery! To drum up business, Leo arranges for a mind reader to come and find hatpin hidden somewhere in the caves. He's joined by 5 others, including his wife, manager, newspaper man, and two people working for the Falls. Ada who is Ruby's friend, has been secretly exploring the caves. She, along with another guide Quinton, are tasked to secretly follow the group, to make sure they get out safely. It becomes a real situation when one of the group is murdered.
It's historical fiction, a mystery, and a bit of romance all in one. I loved everything about it. I had a feeling before I started reading. I mean, look at the cover! But I wasn't prepared for how the setting and characters would grip me. I'm claustrophobic and would never explore a cave, but I enjoyed my time underground with main character Ada and the rest of the group.
Things start out on the slower side, giving you time to get to know Ada. I immediately identified with her desire to try something that she wanted and that she wasn't expected to do. Her love for the caves grew and that made me enjoy the setting. I could see everything in my mind and it's perfect for the mystery that unfolds.
The characters are unique. We get a few chapters from some of them. The rest are from Ada's point of view. The dialogue is fantastic. I loved watching the story and all the scenes unfold. Switching between the tour group and Ada with Quinton was a great way to build tension.
Any one of the group could have been the killer. You'll likely keep changing your mind until the end. Waiting to see if they make it out adds a survival element that is just perfect. I really didn't want the book to end!

Ruby Falls starts off as a strong historical fiction/thriller. We have a interesting time period and very unique setting and a very strong premise. The atmosphere is the best part of this read. It is haunting, suffocating with elements of sensory deprivation slowly eating away at the mental stability of the characters. Eleanore is an unreliable narrator but that is what makes her most intriguing. She is fearless yet anxious and clearly coming apart inside. Though well written the story begins to slow and drag a bit for me. Not so much that I lost interest completely but enough for me to glance ahead and watch chapter length, if that makes sense. The ending almost seemed written by a different author which was unexpected.
Overall it was a well written story that was good not great. If you read books for atmosphere though, this will be the read for you.

Thanks to Grove Atlantic and NetGalley for the e-ARC.
Living in north Georgia, I found the premise and setting interesting, but the story and characters did not hold my interest. Fans of historical fiction/romance/mysteries may enjoy this one.

In 1928, Ruby Lambert’s husband Leo discovers a massive waterfall inside of Lookout Mountain near Chattanooga, Tennessee. He names it Ruby Falls after his beloved wife.
This amazing discovery attracts visitors from all over the world.
Meanwhile, Ada Smith has been exploring the caves of Lookout Mountain alone at night.
Unfortunately, The Great Depression hits Tennessee hard. Leo and Ruby are struggling to keep their attraction open to the public.
Along comes famous mind-reader Jeremiah Hagathorn. He proposes a publicity stunt that Leo cannot resist.
Someone will hide a hat pin inside Lookout Mountain, and Jeremiah will find it using only his psychic ability.
Jeremiah is accompanied by his wife and three others, including a reporter. Ada and fellow spelunker Quinton are secretly hired to follow the crew in case of an emergency.
A simple publicity stunt turns dangerous and deadly quickly.
Ruby Falls is a unique thriller that takes place underground in darkness. The story also becomes a tale of survival!

Oh my! I really loved this different, unique, historical locked-room mystery! It is also based on a real place.
Taking place during the Great Depression, Ruby Lambert's husband, Leo, discovers a big waterfall in of Lookout Mountain. This is where they have been mining, and this discovery is unexpected. People come from all over to see it.
Ada Smith is Ruby's best friend. She has lost her husband, and the depression has hit. She begins exploring the caves and tunnels of Lookout Mountain at night when no one is around. While doing this, she meets a worker one night named Quinton. He does not judge or condemn Ada, but instead gives her advice on exploring, and even joins her at times.
The depression affects their town hard, and especially Leo and Ruby. They made a huge investment and turned Ruby Falls into a tourist attraction with a restaurant, tours, and weekend dances. However, to drum up more business, Leo decides to invite Jeremiah Hagathorn to partake in a PR event. Hagathorn is a renowned mind reader. LEo will have 2 of his most trusted people hide a hat key somewhere in the monstrous caves and tunnels. Then a group of people, including the two hiders, a journalist, Hagathorn's wife, and a tour guide, will go down and Hagathorn will have 12 hours to find it. Unbeknownst to the group, Ada and Quinton are hired to follow the group from a distance to keep an eye and provide a safety net.
However, tragedy happens and Ada and Quinton have to get the other explorers out before another death occurs.
This was a claustrophobic, atmospheric mystery. I really liked most of the characters. I really liked the characters, especially Ada and Quinton. They are intelligent and resourceful. Ruby is also very likable. This is more a mystery than a thriller, but there are tense moments and just an overall dark, closed in vibe. IT is very well written and comes together nicely, and I was a little surprised at the reveal- or more for the motivation behind the crime! Well done!
There is a lot of reflection in the characters, that at times made the story drag a bit. And it is told through multiple viewpoints- but I felt this worked for the story. I highly recommend for anyone interested in a mystery with a unique take on the locked room mystery!
I also highly recommend the author's note at the end. I found it very interesting about the history of the falls!
Thank you to NetGalley and Atlantic Crime for the ARC. This is my honest and voluntary review.

Growing up in Tennessee, I have seen the billboards along highways and interstates for Ruby Falls my entire life. I have even visited there on more than one occasion as a child. So, when I saw there was a murder mystery that takes place right here in my own backyard...sign me up!
We are in the late 1920s, and Ruby Falls is not as fully developed as it is now. We join in progress a situation that involves caves. There isa lot of backstory of the protagonist in the first part of the book. It allows for a lot of depth of character for later.
We do find ourselves with a group that is going deep into the caves. This part of the story has strong Agatha Christie vibes, and I am all for it. When they find themselves in peril, a body turns up. Now, not only are they trying to survive, but they know the killer is one of their own and must find out who it is. If they survive nature, a huge “IF”, they may not survive the killer.
There was only one part of the story that didn’t connect with me and that was a part of sexual tension. I see where it could fit in the protagonist’s story, but it just didn’t seem to fit the rest of the novel.
Check out “Ruby Falls”, the novel. Well, while we are at it, why don’t y’all come on down to Tennessee and visit Ruby Falls. Enjoy some sweet tea. Sit a spell on my front porch. We will talk about books.

Review of advance copy received from Publisher
Thank you @novelsuspects @atlanticcrime for my #gifted copy of Ruby Falls!
Sometimes, I see "historical mystery" and I worry that it will be too cozy for me.
Ruby Falls is anything but cozy. Tense, claustrophobic, riveting. With a real sense of danger as the characters' water and lights run out, stuck underground with a possible murderer.
Ada is a 40something widow during the Great Depression in Chattanooga. When her friend's husband Leo discovers an underground waterfall and makes it into a tourist attraction, Ada reclaims a bit of something for herself when she starts exploring it after hours. She continues to explore even after being discovered by fellow caver Quinton.
Leo invites a mind reader to find a hatpin in the caverns, a PR ploy as restaurants close and bread lines grow. Quinton and Ada follow behind the motley search party as a safety net, just in case trouble arises. And it certainly does.
Ada is a force to be reckoned with. She's spent her life as a daughter and wife and is worried she will now fade into oblivion. She wants to forge her own path. An astute observer of people, the "crooks and crevices" inside all of us that echo the caves.
The first part of the novel sets the stage, introducing us to the characters and the terrifying beauty of the caves. But once the clock starts ticking to finding that pin, the story grabs you and doesn't let go until the end.
This is in no way a romance. But also? I loved the romance angle. 4.5 stars

Review of advance copy received from Netgalley
I wanted to read this book because I have been to Ruby Falls twice and was fascinated by it. I read the synopsis and was intrigued to see how the author would incorporate a mystery into the history of Ruby Falls.
I can say that this was very atmospheric! I give 5 stars to the setting, because I literally felt like I was back there exploring. She did such a fantastic job describing Ruby Falls. I love the historical account in the beginning of how Ruby Falls was discovered also.
The main mystery plot was done really well. I could feel the aggravation the characters were feeling because I was also very aggravated. Had I been in that situation the outcome would have developed differently. There is no way I could have been stuck with those people in that cave.
The one part that I didn't really enjoy was the little romance subplot. It didn't need it and felt very disjointed from the rest of the book. One scene in particular was so out of place that it was more shocking to me than any of the things that occurred in the main plot. This book was intriguing enough without it.
I would recommend this book to anyone who is an explorer at heart and wants to add a little mystery in their reading..
I give this book a 3.75 rating rounded up to 4.

First off, let me just say, I LOVED this setting! Ruby Falls is a beautiful place. It is not very far from me. So to have a book set here just made my day! Plus, I learned so much about the history!
This story is so atmospheric and has good intensity! It takes place almost completely underground in the caverns of Ruby Falls. It has little bit of everything, romance, science, history, murder and mayhem!
And the characters!! I fell hard for Quinton. He is the strong silent type! Ada is a good girl but she does not always follow the rules and this just endeared me to her! And let’s not forget the crazy psychic. You talk about a piece of work!
Need a story about more than one discovery…THIS IS IT! Grab your copy today!

Review of advance copy received from Goodreads Giveaways
Ruby Falls by Gin Phillips absolutely wrecked my nerves in the best possible way.
This book is basically one long anxiety spiral — and I mean that as the highest compliment. From the very first chapter, I felt trapped right alongside the main character, and the tension just never let up. It’s claustrophobic, intense, and deeply psychological without ever feeling overdone.
What really stood out to me was how personal the danger felt. It wasn’t just “something bad is happening.” It was layered with emotional stakes, complicated relationships, and that constant creeping dread that something worse is just around the corner. I kept thinking, okay, surely we get a breather now — and nope. We do not.
Gin Phillips does such a great job capturing fear in a way that feels raw and realistic. I could practically feel the panic through the pages. And yet, it wasn’t just nonstop chaos — there were quiet moments that made the characters feel real and grounded, which somehow made everything scarier.
This was the kind of thriller that makes you forget to check your phone, forget what time it is, and maybe double-check your locks before bed.
Easy five stars for me. If you love tense, character-driven thrillers that make your heart race, this one absolutely delivers.

Review of advance copy received from Netgalley
Ruby Falls stands out most for its setting and atmosphere. The underground caves during the Great Depression are eerie, claustrophobic, and beautifully rendered—the sense of darkness and isolation is constant and effective. The setting easily feels like the strongest character in the book.
Ada is a compelling protagonist: grieving, restless, and drawn to the caves as a way to feel alive again. Her partnership with Quinton was a highlight, and the locked-room-style mystery built around a publicity stunt gone wrong is a strong, intriguing premise.
However, the pacing held this one back for me. There’s a lot of reflection and introspection, which adds depth but slows the momentum, and it takes a while for the tension to fully kick in. The ending resolves the mystery, but the tonal shift felt a bit abrupt.
Overall, this is a well-written, moody historical mystery with a truly unique setting, but it leans more atmospheric than suspenseful.

Ruby falls wasn’t exactly what I expected- Roughly 99% takes place in the caves, which I should have anticipated from the title, but somehow didn’t. In addition, the mystery, while interesting, doesn’t start up until relatively late in the book; the first half primarily establishes the characters and environment. Those hoping to solve the mystery along with the main character while reading may be a bit disappointed, I don’t know that we are intended to be able to.
Regardless, I enjoyed Ruby Falls. Without too many spoilers, the author’s style, particularly towards the end, really captured the mental and emotional state of the main character. In fact, their style kept me engaged throughout, even through the establishing first half.
Definitely recommended, even for those who haven’t visited Ruby Falls, though with the caveat that it’s a bit of a slow start.

Growing up in East Tennessee myself, I was drawn to this historical fiction called Ruby Falls. This book follows Ada Smith, strong female main character who explores the caves on her own at night. This story is so intriguing and has amazing character development. If you like caves, a good mystery/ thriller, or historical fiction, pick up this book and dive in. During the Great Depression the cave needs a new stunt or gimmick to draw in customers. They decide to enlist a mind reader and mystic to explore the cave in search of a hidden hat pin in the caves. Cute right? That's when the story turns! Tragedy strikes. Ada and her partner have to figure out what happened and get everyone out with losing another member of their party. Think Murder on the Orient Express but in a spooky cave with some smart characters. 5 stars!
February 13, 2026
Oh goodness, the description of Ruby Falls had my interest piqued, plus as a Chattanooga native I was excited to read fiction set around the time of the falls' discovery. Unfortunately, in the end it didn't quite work for me. The start is strong--I really felt Ada's loneliness after her husband's death and her jealousy of Ruby. Her clandestine exploration of the caves helps the reader understand her state of mind.
However, the second half-ish, following the crew searching for the hatpin, gets a little tedious. The murder mystery seems almost secondary to the rest of the story, which is more of a self-examination and a budding romance. At times, it feels like two books mashed together. Read it for the beautifully written early chapters, but don't expect a gripping mystery.

I absolutely LOVED this book! I have loved all of Gin Phillips books and expected nothing less from Ruby Falls, but this book is next level. There are no new stories, only new ways to tell them. The story is a good one, the storytelling, masterful. The way in which these richly drawn characters evoked the picture in my mind’s eye, far exceeded my expectations. I was so drawn to them that for the duration of the novel, I felt truly surrounded by their presence. Her writing is so beautiful, I feel as if she deliberated over every single word. Ms. Phillips’ novels always feature strong women and Ruby Falls is no exception. Ada is a strong woman who knows who she is and knows what she doesn’t know. She is wise beyond her years. You will love her! Preorder your copy now. Available March 3, 2026. You’ll thank me

A closed room (err cave) mystery done differently and well. I loved the period of time this was set in and the fact that Ruby Falls is a real and beautiful cave system.
It took me a bit to get into this as the beginning was lagging a little. Once it gets going, you get to learn a lot about Ada and her love of exploring this cave. As someone who has a degree in Geology and earth sciences, I enjoyed the bits of mineral talk and exploration. Having been in caves I could really feel the claustrophobia oozing from every page.
I grew to enjoy Ada and I liked being in her head even if at times she was losing it.
If you enjoy mystery novels with decent twists, an interesting setting and time period, this is a solid read.
Thank you NetGalley for this ARC

Thank you to netgalley and the publisher for the arc of this. I was very interested in the idea of a murder mystery inside of the caves of Ruby Falls. I went to Ruby Falls earlier this year, and the setting really was similar to the real place. The setting and how the caves were brought to life were really good. I wished this story had more suspense. There was so much potential for a great, high stakes mystery but this read more like litfic with mystery. That’s not really my thing. I think if you prefer cozy mysteries or a lighter mystery, this is more geared toward you.

Review of advance copy received from Edelweiss+
As a native Tennessean, I found the premise to be interesting. Unfortunately, the execution was disjointed and unexciting. The whole book feels unsure of itself. Does it want to be historical fiction? Does it want to be romance? Does it want to be a thriller? The story dabbles with a little bit of all three, but by the end, I just wanted it to pick a lane.
I appreciate Edelweiss and the publisher for making the ARC available. Perhaps the ARC is an early draft that got retooled, and the physical for-sale edition will be more cohesive. Here’s hope.

Review of advance copy received from Goodreads Giveaways
I found "Ruby Falls", by Gin Phillips, to be an okay read. The story was well-written and the main characters, Ada Smith and Quinton were interesting enough, at least in the beginning. As the adventure continues in the cave with the various characters, I found the plot to become quite tedious. In my opinion, the storyline did not move as quickly as it should have. I found myself losing interest. Overall, the idea and timeline were interesting and unique. If you're looking for a slow paced mystery, you may find this one interesting.

This book was given to me by Goodreads.
It is similar to a closed room mystery although it takes place in the cavern where Ruby Falls is located.
Even though it is slow getting started, there are many twists and turns to keep your interest.
The Sept. 23,1932 chapter explains the outcome for some characters but I wished 2 more characters were included.
I have visited Ruby Falls in the past and was able to see in my mind, the cavern and challenges that the characters faced.
If you have visited Ruby Falls, you will enjoy this book.

I can’t tell you how many times I’ve driven by the sign for Ruby Falls. I think that’s probably what drew my interest in this book. Plus I have been in several of these type caves.
This was a good mystery taking for the most part underground. It was descriptive, you could hear the water drip, see the shadows at the edge of their lights.
I did think it dragged a little in the middle. I wasn’t entirely surprised by the ending. It’s perfect for fans of a locked room murder.

Ruby Falls takes place underground in the dark which makes it unique. Apparently it is a real place so that adds into the story. This is a well written mystery with good characters and a surprising who dun it. It is told through multiple characters, so that can be a bit confusing. The book is full of mystery and intrigue though.

A DRC was provided by Edelweiss in exchange for a fair and decidedly not meandering review.
Good, not great, historical fiction. Strong start in an interesting time period and unusual setting, then the story loses its way. The reader feels like one of the characters lost in the caverns, but there's some lovely writing that carries through to the end.

Quite a twist on a locked in mystery having it taking place in caves! I loved the characters and the suspense builds with each chapter until it starts to make you want to race to the end! Many thanks to the author for this early copy for reading and review

Wow! I got this book as an ARC and had Nonidea about it. It was wonderful. Very slow paced, but meandering like an underground cave. So many intriguing characters and a very good mystery.

Ruby Falls by Gin Phillips is a compelling and suspenseful novel that captivates readers from the very first page. The protagonist, Ada, emerges as a remarkably resilient and complex character, shaped by the many challenges she has faced throughout her life. The narrative begins prior to the discovery of Ruby Falls, but the true heart of the story unfolds as Ada becomes involved with a rescue team.
Without revealing too much, it is worth noting that the character development in this novel is exceptional, and the plot is rich with tension and intrigue. Phillips masterfully crafts a “whodunnit” that keeps readers guessing until the very end. I found the book difficult to put down, and would highly recommend it to anyone who enjoys mysteries and suspenseful fiction.

my staff pick review -
i loved this book! i admit that it took me a few days to get into it, but once the crew was underground, i couldn't put it down! the story is told primarily from Ada's perspective, but occasionally shifts to the characters that have never been in the caves, and we are privy to their dynamics as they are led deeper and deeper by a wild man who will stop at nothing to achieve his goals. at once touching and suffocating, this book will drag you into the depths right alongside them, and you will crave it. in three words: tense, intimate, and claustrophobic.

my edelweiss review -
I LOVED this book! I admit it took a few days to really get into it, but once the crew is underground, I couldn't put it down. It's claustrophobic, it's intense, it's nerve-wracking, but it's still captivating and at times incredibly intimate and touching. The story is told primarily from Ada's perspective, but it occasionally switches to other perspectives to explore mostly other character dynamics that Ada isn't privy to, but also the private thoughts of the characters who had never before experienced the caves in any capacity, let alone with a time constraint and a wild man leading them deeper and deeper. I rate this a nine out of ten, but if we're talking stars, it's a five out of five for me. Expect this treasure on March 3rd, 2026!!
