This is a Romantic Suspense, and this is the third book in the Secure One series. I have not read the other books in this series before picking up this book, but I did not feel I was missing anything. I do think this book can be read as a standalone. This book is a fast paced book that is packed with suspense and action. This book kept me guessing and wanting to find out who was the killer which made me keep reading. I really loved getting to know the characters. I felt the two main characters are perfect for each other, and they help heal each other. Their romance was not cute and sweet, but it was perfect for them. I really enjoyed reading this book. The ending of this book was wild, and I really did not see it coming. I was kindly provided an e-copy of this book by the publisher (Harlequin Intrigue) or author (Katie Mettner) via NetGalley, so I can give an honest review about how I feel about this book. I want to send a big Thank you to them for that.

This is Mack and Charlottes story in the series- none have been a disappointment- all deal with past wounds, scars or ghost and overcoming those to find love. Great suspense and intrigue- didn’t see the ending of this one coming. Looking forward to more in the series!

In The Red River Slayer (Secure One #3) by Katie Mettner, stopping an infamous serial killer requires the Security One team to confront their pasts when women's bodies are discovered in rivers over three months. After a fourth woman is found dead in a river near Security One headquarters, security expert Mack Holbock investigates the case and searches for a clever serial killer with the help of Charlotte, a traumatized sex trafficking survivor.

The wonderfully developed relationship between Mack and Charlotte and Mettner's well-constructed action/fight scenes and gripping suspense that kept me on the edge of my seat is what drew me into this novel and kept me glued to the pages. I love Mettner's active, straight-to-the-point narrative style, vivid, detailed, descriptive writing, and superb worldbuilding that make you feel like you're right there with the characters in each moment. Reading her novels is like watching a well-written and produced criminal investigation, crime drama, mystery/thriller movie, or TV show.

Haunted by the past, kind, quiet, gentle, and accepting, Mack is a disabled vet. Consumed by guilt, Mack focuses on trying to right wrongs in the world, leaving him no room or desire to have love in his life. But when Mack meets Charlotte, he becomes possessive of her and concerned for her recovery and safety, especially when they face danger investigating the serial murders. Mack feels driven to protect Charlotte and win her trust, but he cannot fall in love with her.

A formerly homeless sex trafficking survivor whose wounds aren't visible, Charlotte suffers from nerve damage in her legs from the abuse she suffered. Her self-esteem and confidence are terrible because of the awful things she's been forced to do to survive. Coming to Secure One has been her salvation, allowing her to heal and find a supportive family, team, and home. But best of all, it brought her Mack, who makes her feel safe—except for her heart. He affects her in unfamiliar ways she doesn't quite understand. But she knows he's a danger to her heart because she believes she's unworthy of someone like him and could easily give him her heart, which is dangerous. Charlotte comes into her own working as Secure One's kitchen manager and helping Mack investigate the murders of the young women found in rivers. However, being in the field forces her to face and overcome her fears and deal with a past she cannot escape.

I love Charlotte and Mack's relationship. Their connection and attraction are instant, strong, and deep, leading to Mack and Charlotte becoming friends and companions almost immediately. The respect, honest communication, and give-and-take between Charlotte and Mack are sweet and swoony. To Mack and Charlotte's surprise, they fall for each other, believing the other deserves better because they aren't good enough. All Mack and Charlotte want is to be the one to help each other heal. Mettner transitions their relationship from friends to lovers through steamy, intimate, sweet, and sexy kisses that lead to closed-door intimacies that are sensitive to and respectful of what Charlotte has experienced.

Mettner continues developing her genuine, complicated, fallible, empathetic, intelligent, and likable characters. The novel features fantastic disability and mental health representation with its security team of disabled and recovering trauma survivors. It has humorous, snarky, supportive, and emotional interactions with a found-family feel.

The relationship and suspense plot are slightly more self-contained within this novel and easier to follow, so they flow better—even though they're still interconnected with the first two books. A thrilling, sexy, emotional, fast-paced, suspenseful, and romantic novel, The Red River Slayer explores themes of self-confidence, self-esteem, first love, letting go of the past, healing and recovery, disability rep, PTSD, learning to trust, sex trafficking, criminal activity, serial murder, and mental illness.

I love this excellent romantic suspense series. I love that there is romance, but also elements of procedural thrillers which are one of my favorite mystery sub-genres. I've been reading the books in order, but they can be read as standalones. Each book focuses on a separate investigation and potential couple, but many of the characters continue through each book. Secure One is a successful security company staffed with former Army Special Forces soldiers who served together and are as close as brothers. Each has scars from what they went through, but are trying to heal themselves as they help others. The love stories are heartwarming, but the cases are suspenseful and thrilling.

This is the third book in the series and is my favorite so far. The couple which is the focus of this book is Mack and Charlotte, both strong characters who are helping each other get over trauma in their pasts, learning to trust others and themselves. Mack, Charlotte, and the rest of Secure One are trying to stop a serial killer before there is another victim. This is a fast-paced, entertaining read. I was intrigued by the investigation and enjoyed how things turned out in the end. I can't wait to read the next in the series.

Would it be weird to go back to page one and start again? 😊 Yes, I liked it that much.
This gripping romantic suspense keeps the readers on the edge of their seats from beginning to end. Written with skillful pacing and intricate plot twists, this book delivers a thrilling ride that will leave readers guessing until the very last page.
As always with Katie Mettner’s books, the real strength lies in its well-developed characters. Mack and Char are both complex and compelling, each grappling with their inner demons as they navigate the dangerous world of hunting serial killers—and love. Katie does an excellent job of fleshing out their backstories and motivations, making it easy for readers to empathize with their struggles and root for their success.
The romance adds an extra layer of depth to the story as Mack and Charlotte navigate their growing attraction amidst their insecurities and the chaos surrounding them. Both have issues that force them to hold back, but Mack’s need to protect her and his kind understanding is heart-warming, which is exactly what Charlotte needs to realize that she’s worthy of love and affection. Charlotte saw something different in him too, that softer side that conflicted with the hard exterior he often showed. She’s exactly what he needed to help him realize he’s also worthy of love and affection. All of this added a layer of depth that is often missing in today’s romance novels.
While the journey to uncovering the truth is filled with twists and turns, it’s the ending that makes it worth the roller-coaster ride! I’m not telling, though, no spoilers here! With its well-drawn characters, intricate plot, and pulse-pounding suspense, The Red River Slayer is a satisfying read for lovers of romance or suspense, but it’s perfect for Romantic Suspense lovers like me. Go get this 5-star read! You won’t regret it!

Mack Holbock works for Secure One; when another body is found in the river he and Charlotte are on high alert. Charlotte was once a captive of The Miss and is just now getting over her ordeal.
Charlotte was at a party for the senator's daughter and had taken her to the bathroom when she was attacked. She fought off the attacker and saved the sixteen-year-old Ella. The attack was when the police and FBI were there about the latest body found in the river. As Mack and Charlotte work on theories to catch the killer even Ella has some insight into the murders.
Mack and Charlotte have been trying to avoid attraction to each other; but as they work to find the killer the attraction grows. They go to Pennsylvania when a couple are found in the river sure they are party of the slayer's victims.
Love the suspense book and have really enjoyed the series.

This is the third book in the Secure One series and gives us the answers we’ve been waiting for. Katie writes amazing books and this one is full of suspense, action and a bit of love.

This is Mack and Charlotte’s story - they are both amazing characters that have trauma from their past that they deal with on a daily basis. They are both extremely strong, determined and protective of those they care about. They are committed to work with their team to finally bring down the Red River Slayer. This book will have you in the edge of your seat the entire time.

Katie’s books are very special as they teach readers about different disabilities that people live with every day. Highly recommend this book and the entire series. They can be read as stand alone but I recommend reading them in order to understand the back story and the characters.

The serial killer the Red River Slayer dumps a new body which sets the stage for the third installment of the Secure One series. Are the girls turning up dead part of what Charlotte was involved in? Could she know who they are? Charlotte has been a cook at Secure one and has become part of the team but has been slowly trying to heal from her trauma when she was in captivity.
Mack has been trying to heal from his own tragic story. Even though he is a disabled vet, he has become a valued member of Secure one. He is in protection mode since he first met Charlotte. Protecting Charlotte will be easy, protecting his heart from her will be a little harder to do.
This book steps up the action in the series, and the intense emotion between these two is palpable every time they are together. I love seeing the author bring out the characters flaws and follow how they evolve throughout the story. The two broken souls were a joy to read and get to know. Katie writes a great story that you can't help but love the characters, the camaraderie, and the family feeling among the group. I highly recommend this series.
Thank you to the author and the publisher for the arc of this awesome book.

I fell in love with Book 1 in the Secure One series and loved the second one even more. However, there’s just something about Charlotte and Mack that puts them in the lead for my favorite (I’ll probably say this about the next one too).

This book was action packed and I was definitely on the edge of my seat. I’m sad it’s over but I know the next one will be here before I know it.

Thank you Katie for an ARC, your books are always a delight to read.

Wow... not a cozy...haha
I sort of thought it would be, a cozy mystery, but nope..
A good plot line, though and I want to know more about "Secure One"...
A security company with all vets.. vets of one war or another..
Either as military men/women or as fighters of street crimes.

This is book 3 in the Secure One series. You can definitely read it by itself but I liked that I had read the first two before embarking on this one so I had some background.

Mack has "done good things for good people in the name of justice" which I respect and love about his character. He has some scars and like Katie's other books, he represents those with disabilities that are undercover heroes.

Charlotte needs to heal and learn to trust that not all men are bad. Mack is the perfect person to help with that and heal himself at the same time. He accepts her for who she is and that is what she needs the most. There is a fierce little lioness inside waiting to get out and protect so many others like her.

This series has always been about helping women that are being held against their will. This story was my favorite in the series and it was also the most intense. The Red River Slayer is killing women and they are being found every 6 weeks. The FBI is supposed to handle the case but Secure One is what this case needs most. This installment of the series was so good, I ended up reading it all in one sitting.

Katie Mettner has done it again in expertly crafting a great suspense story that you can enjoy whether you are reading this book alone or as part of the series filled with characters that now feel like friends.

Terrific book that kept me hooked from start to finish. In the earlier books, the operatives at Secure One successfully stopped a trafficker and her subordinate, rescuing women who had been held captive. In both books, some women's bodies were found floating in rivers. The killer was dubbed "The Red River Slayer" and has remained unidentified for several years. This is Mack and Charlotte's story. Both were supporting characters in the earlier books.

Mack served in the military with the other team members and was injured in a mission that went wrong. His memories haunt him, and he feels guilty that he couldn't stop what happened. Charlotte escaped the clutches of The Miss, but her experience left her traumatized and wary of trusting anyone. Mack has been protective of Charlotte since the day she arrived at Secure One. I loved seeing him support her and work at building her confidence.

As the book opens, Secure One provides security for a senator's daughter's birthday celebration. When the body of a murdered woman washes up on the riverbank, Charlotte recognizes the woman as another of The Miss's captives. The team believes she is another victim of the Slayer, and there is a connection between the murder and the cases they worked on. They suspect that it is just a matter of time before there is another victim.

This action and suspense-filled story kept me glued to the pages from start to finish. Mack and Charlotte take the lead in the investigation with the backup of the rest of the team. Charlotte's artistic skills come in handy as they plot the killings and try to make sense of them. They get help from the senator's daughter, who brings a different perspective. There is also an unexpected arrival from Charlotte's past, which provides a link that sends her and Mack on a desperate journey. The final confrontation was a nail-biter with a surprise revelation.

I enjoyed the development of Mack and Charlotte's relationship. Mack is such a tough guy on the outside, but his kindness and sensitivity toward Charlotte show a softer side to him. I loved watching him build up her confidence and show her the respect she deserves. The more time Mack spends with her, the harder he falls, but he is convinced he doesn't deserve anyone's love. I loved watching the changes in Charlotte as she healed. She has confidence in herself and her abilities. She is also very empathetic and sees past Mack's tough-guy façade to the hurting man inside. The picture she drew of him was heartbreaking and blew him away with her perceptiveness. Despite her self-assurance, she believes her past makes her unworthy of anyone. It takes nearly losing each other to realize they are exactly what each other needs.

One of the things I love about this series is the author's matter-of-fact treatment of her characters' physical challenges. They aren't made a big deal of; they are simply part of who the characters are.

This continuation of Mettner’s romantically charged thriller series gives Charlotte and Mack, supporting players from Book 2, their own story. Charlotte has assumed kitchen duties for Secure One as she continues to heal from the trauma she suffered at the hands of The Miss and The Madame, antagonists from the previous books in the series. With scars both physical and psychological, she grows more self-assured with each passing day, yet she truly believes she will never be good enough for anyone else.

Mack Holbock is one of Secure One’s finest team members, and he is struck with an overwhelming urge to protect Charlotte from the moment he first laid eyes on her in the previous story. Where she sees weakness, he sees strength, and he takes every opportunity to bolster her flagging self-confidence. But Mack is pursued by demons of his own, haunted by the memory of a mission gone wrong where lives were lost, and he suffered his own irreparable physical injuries. He blames himself and feels unworthy of understanding or forgiveness.

The Secure One team has been providing security for the various events Senator Dorian holds at his private riverside getaway. When the body of a murdered woman washes up on the riverbank during one of these events, the team fears that it is the work of The Red River Slayer, a serial killer who has gone quiet for the past couple of years. When Charlotte recognizes the victim as one of the women pressed into service by The Miss, Mack and his team work to discover the connection between this new murder and one of their most recent cases, but time isn’t on their side. If it IS the work of the notorious serial killer, odds are good that it is only a matter of time before the next body turns up.

Mettner really ramps up the tension in this third outing, with more action and suspense than in either of the two previous entries. Charlotte and Mack make a formidable team as they puzzle through what is happening, leading to an explosive climax neither one will ever forget—oh geez, that’s corny, but you can take it whichever way you like. It probably applies…

As before, I confess that I’m still invested more in the thriller aspect of this series than the romance, but this one really stepped up its game in that arena. I was flipping pages fast and furious to find out what happened at the end. I suspect you will be, too! And also, as before, I’d like to mention that I have a special appreciation for Ms. Mettner’s inclusive writing for the Disability Fiction genre, as I had a sister born with spina bifida. I’m writing this review on what would have been her 60th birthday, and these are adventures she would have truly loved.

Another fantastic addition to the Secure One series by Katie Mettner!! Although this book can be read as a standalone and one could easily follow the plot, there are several characters and mentions from the previous books that it would be beneficial for the reader to read those -- and believe me that reading the previous books you will NOT be disappointed!! I look forward to her continued projects in this series.

This book's romantic interest focuses on Mack and Charlotte. Previous books introduced these two to these characters near the end of book 2. I've been waiting to read their happily ever after, and Katie did not disappoint! Of course this is a romantic suspense book so no happily ever after comes with no problems obstacles or mysteries to solve/uncover. This book focuses on a serial killer coined "The Red River Slayer" and Secure One's involvement in solving and uncovering the killings. There's plenty of action and suspense that will leave you turning the pages quickly to find out how it ends and to make justice is served!!

Mack and Charlotte are perfect for each other. Each carry their own PTSD - Mack from the military and Charlotte from her time held captive and imprisoned under the Madame. Although the story is about uncovering the Red River Slayer, this story is also one on a deeper emotional level. How one battles the demons and instead of succumbing to the mental torture but empowerment and mental strength to come out on top. Both are so insightful and gentle with each other and yet unaware how truly capable they are in the beginning. I love Charlotte -- loyal, artistically talented, plenty of inner strength, and an underestimated physical strength and smarts. Mack, all big and macho on the outside, but has a sweet and sensitive inside that Charlotte brings out.

Clean language, the physical scenes of passion are tastefully done, and nothing overly graphic/detailed when it comes to the murders. With each book Mettner writes, she always highlights to readers about different disabilities that people live with every day and how they are overcome mental battles with it.

Thank you to NetGalley and Harlequin - Romance | Harlequin Intrigue for the advanced copy. All my thoughts and opinions are my own.

Woot! Woot! There is just something so satisfying about reading a book that you know is going to answer the questions that you have had for the past two books. The ending was so incredible that I wanted to get out my poms and poms and cheer. The ending was just icing on the cake with a cherry on top.

The Red River Slayer (a name the press has given to a serial killer who is haunting law enforcement) has struck again. Some of my favorite heroes who make up the agency known as Secure One happen to be handling security at a Senator's party when the body is found. Secure One is made up of heroes from different walks of life. Some of them bear the scars from their days in combat and others bear scars (both physical and mental) from some depraved individuals. These people understand each other and use their bright minds and abilities to provide not only security for those that need it, but also assist law enforcement in solving crimes. They do not allow fear to keep them from seeking justice for those that need it.

This is Mack and Charlotte's story. They both need to face their past in order to live in the future. I think this may be my favorite story in this series thus far. Mack is precious with his loving and caring attitude. I just wanted to squeeze him. Charlotte needs to feel real love as all she has ever known is manufactured or bought love.

This is a fantastic mystery, but it is so much more. It is taut, raw, powerful and traumatic suspense all bundled together with a little dose of romance and healing. As I literally flew through the pages of this book, I knew this book would easily be rated five stars, but worthy of so many more. Now I am ready for some more Secure One. These characters have stolen my heart.

Thank you to the author for this ARC. I am leaving this review voluntarily.

This is the third book in the series but they can all be read as standalones. This was the first book in the series I read and I didn't waste any time going back and reading the first two. While you can read them separately, I definitely recommend reading all of them together. It really just brings the series together and provides a better and deeper understanding of the series as a whole.

Mack is one of the team members on Security One and is the security expert. But he is also struggling under the weight of a whole lot of guilt, past trauma, and scars. As a disabled veteran, Mack has a lot going on in so many ways and gives it his all each and every day to do his best to save the world and all of those living in it. He certainly isn't the type of character who was thinking about being in a relationship or finding someone to spend the rest of his life with. But isn't the best time to find a soulmate when you aren't looking?

Charlotte is a survivor through and through, figuratively and literally. She recently survived trafficking and has scars emotionally, mentally and physically. I think that has a lot to do with why she and Mack were so drawn to each other right from the start. They were immediately protective of one another and they formed an immediate bond that ran deep. While there was more than enough action to keep me hooked on this story, the emotion and level of depth in this book was incredible on its own as well.

I definitely recommend this book and the entire series along with the author. Especially if you want to be on an emotional roller coaster that is full of danger and suspense and the hunt for a killer.

I absolutely love this series! Each book is a page turner with so much suspense and romance in each one. This book brings Mack and Charlotte together at Secure One. Mack works for Secure One and Charlotte is the cook. She was rescued in book two. The chemistry is definitely there, but both aren’t quite sure at first how the other feels toward the other.

Throughout this book, Secure One is on a mission to stop the person responsible for woman showing up on the river shore dead. It’s a race against time before another murder happens. While doing security for the Senator’s daughter, a body washes ashore. It’s Charlotte who recognizes her. Also, a woman shows up who was running from someone. They know they need to protect her.

Charlotte draws a map and Secure One try to hone in on any clues to the person responsible for killing the woman washed ashore. Who could it be? Will they stop this person before more woman die? There is one person who washes ashore embraced with one woman. Who is that? Wait til you find out!

While working together to find the Red River Slayer, Mack and Charlotte definitely become closer. They share their stories and what has happened to them in the past. Mack’s story of how he lost the nerves in his legs is so touching. He’s definitely a tough cookie though. Will Mack and Charlotte come out with their feelings in the end to each other?

The Red River Slayer is the third book in the Secure One series. This book is fast-paced, daring, suspenseful and entertaining read. A brilliant, well-paced and well-written story with a healing journey, a protective hero, a vulnerable yet strong heroine. The Red River Slayer is fast-moving from the first page with intriguing plot and mystery that will have reader invested in characters and storyline.

Secure One work together on a mission to stop an infamous killer of women that end up dead in a river. Mack, a security expert, who works for Secure One takes on the search for a cunning serial killer. Charlotte is the cook. Both are jaded and distrustful. Their story is emotion-charged, intense and suspenseful. Even though he was claiming he has no heart, he proved time and time again the opposite with his actions. There is something about their connection that feels real, touching and honest. Nothing could have ever prepared them for meeting each other and the amount of the attraction they feel. Their build-up while danger was surrounding them was crafted skillfully with slow-building tension, romance and suspense.

A phenomenal / whimsical read.

This is my favorite Secure One book yet! I absolutely adore Mack and Charlotte. They're both such authentic and deeply human characters, each dealing with their own PTSD from past trauma. Mettner deftly weaves the tapestry of their complicated emotional lives with care and sensitivity. Watching Charlotte and Mack navigate their past trauma while confronting their deep feelings for one another was moving. Charlotte is a powerful character, a woman who has gone through horrors no human should ever have to endure only to rise like a phoenix into the new life she's made for herself. She is courageous and badass and I absolutely loved seeing her growth. Mack is perfection. He's perceptive and patient and an advocate for the woman he loves, giving her the support she needs to grow and take back her power. He actually sees her rather than trying to save her. These two souls recognizing the deep connection they share is extremely gratifying. Oh, and did I mention they're hot on the trail of a diabolical serial killer? The suspense aspect of this book is also captivating with a serial killer who is fresh, original, and deeply frightening. The tension mounts as the team at Secure One--with the help of a Senator's daughter--work to solve the case before another woman is killed. Charlotte's fierce determination to stop more women from being victimized puts her and Mack on a collision course with the Red River Slayer. You won't be able to put this down.
