Rival Hero: A one-night stand workplace rivals romance (Redleg Security Book 4) Kindle Edition
I only went into the bar to scope out my competition – him.
The scorching hot night that followed was a mutually pleasurable accident.
Of course I knew we were in the running for the same position.
It’s not my fault he didn’t know who I was.
Gathering intel is my specialty.
Maybe if he were better at it, he would have gotten the job instead of me.
I tried my hardest to resist our chemistry, but he was too damn hot.
Too charming. Too funny. Too masculine.
And he smelled so freaking good.
My hormones took over.
Now we're working together on the Redleg Security intelligence team.
Every day. High stress. Close quarters.
Sexual chemistry off the charts.
But he hates me.
The thing is… he should hate me.
I treated him like a pawn.
But he’s a real man with dreams, passion, and pain.
And I’ve never wanted someone as much as I want him.
But it’s too late for us.
I made us rivals when we could have been so much more.

Author's note about reading order:
Rival Hero is Book 4 in the Redleg Security Series. Each book in this series features a different couple, including their happily ever after and is a "complete story" with no cliffhangers. However, the series is best read in order to avoid suspense-related plot spoilers. Each book starts right where the prior book ends. If you do not wish to read them all, then you can read as a stand-alone. Also, the books get spicier as the series progresses.

About the author

One day during the COVID quarantine (a.k.a. the dark time), Jackie was reading yet another laugh a minute rom-com by Lucy Score or Pippa Grant, and she thought to herself - hey, I can do that. And so, she did and it turned out even better than even she thought possible.
Jackie is a fresh face on the romance author scene destined to shake things up with her signature blend of light-hearted comedy, over the top characters and romantic heartwarming moments. A voracious romance reader herself, Jackie writes stories featuring the four S's: Snark, Swoons, Steam and Sarcasm. Her heroines are bad-ass and her heroes are easy on the eyes and heavy on the charm.
When she is not writing funny stories about swoony heroes and the women who get to play with them, she is reading all types of romance novels or taking care of her army of cats and her teenage son (who also speaks fluent sarcasm).
Follow Jackie so you don't miss out on her new releases, which are destined to be topping the best seller lists.

Rival Hero is the fourth entry in the Redleg Security series, and I can say without a doubt it is now my favorite. Although the first three books are pretty great, too. Each book in this series picks up right where the previous book left off, so I highly recommend reading Heartbreak Hero, Forbidden Hero, and Comeback Hero first, but this can be read as a standalone since the author provides enough backstory throughout for you to be able to follow along. Rival Hero features our heroine, Mia, who is a wonderfully and at times beautifully painfully flawed, perfectly badass CIA Intelligence officer with mad skills when it comes to technology and digging up secrets. She's got wounds from her past that have taken their toll and have largely led to a lonely existence. Our hero Klein, appears to be a former Army Ranger and full time cinnamon roll at first glance, who listens to the Rat Pack, bakes, is loyal to his friends and devoted to his family, and is a gentleman who is ultimately looking to settle down and start a family. As we get to know our hero throughout the book we get a delicious surprise when it turns out this cinnamon roll has a deliciously gooey Dom center, and the angst and chemistry between the two MCs is what is responsible for waking it up.
This book finds our heroine seeking to get out of the CIA and start healing some of the damage of her past, but not before she she uses those skills to to dig up some dirt on her rival for the job she wants at Redleg the seemingly sweet human version of a golden retriever, Klein (Cal to eventually to Mia and his family, Klein to everyone else), yes, Calvin, really his name. As the book progresses we (and Mia) learn he's also carrying a few secrets of his own.
The beginning of our story finds Mia intentionally seeking out Klein for a little recon only she doesn't expect to be quite so attracted to him. The chemistry between these two is present from the first meeting and ignites immediately and only burns hotter as our two MCs quickly turn into rivals forced into grudgingly close proximity through an unexpected decision from Boss. (One item of note: The scenes with Klein and his mother who has early onset Alzheimers were at times both heartwarming and heartwrenching and you could feel the absolute devotion he had to making her comfortable as the disease progressed. But these could be difficult for anyone who is dealing with this topic or that of losing a parent in real life so I'd advise the reader be aware of that before starting this book as it is a central plot point.)
(Sidenote, I am excited for the next two planned Redleg books, but now I really need Jonesy and Aaron's books...) After both Klein and Mia are blindsided by Boss's decision that forces them into one another's orbit more and more frequently, the anger, the sass, and the lust reach epic proportions.
Throughout the book, it's clear to everyone else at Redleg that they have a past but neither Klein or Mia are speaking up. The book has what I would classify as a mostly classic enemies-to-lovers vibe woth some twists and turns and of course some seruous escalating the bad blood between them. But this definitely doesn't dampen the chemistry or the lust between these two characters. Eventually, the hostility and lust reach epic proportions and it's clear something has to give when little blow ups start to happen that even the mkat oblivious Redleg guard notices.
The shift from enemies to lovers begins with one of the spiciest scenes I've ever read, if D/s dynamics are not your thing, this scene and this book probably won't be your jam as the rest of the bedroom scenes are equally spicy. The shift between our MCs isn't instantaneous though, which I appreciated as it felt realistic. Even as things begin to shift both Klein and Mia still have their individual issues to work through before they can teuly make something work all while attempting a daring and risky rescue of someone important to Redleg. I liked that this book villains are tied to the previous books in the Redleg series and that also makes the case for reading the previous books in this series.
Mia's passion for using her skills,
skills which initially contributed to the enemy situation with Cal, to help victims and her willingness to support him go along way toward helping Klein take that leap from enemy to lover and Klein's genuine goodness, care and concern for his family, everyone he cares about, and Mia herself, result in her taking that leap from enemies to lovers right along with him. not everyone is out to harm her or those she loves. These two were made for each other and while there was some pain getting there and at times for personal reasons, reading Mia felt a bit like an uncomfortable mirror, this was a book I couldn't put down and worth every minute of housework I skipped to finish it.
Take a guaranteed HEA, a cinnamon role hero with some delicious hidden Dom tendencies, a badass heroine who's willing to (eventually admit her mistakes) and actually enjoys handing over the control sometimes, add in some of the spiciest bedroom scenes from thus author to date, and some by turns beatifully heartwrenching and heartwarming scenes with Klein and his mom, and of course appearances by our favorite previous Redleg couples and guards and a cliffhanger for the next two Redleg men to get books and hoo-boy, do we have yet another winner. This book is definitely my favorite entry in the Redleg series and Klein is tied with my OG choice, Hudson from Love and Other Mistakes, for favorite book boyfriend from this author's books. I can't wait to see what comes next for our Redleg men and women.
One thing I particularly want to note, I really appreciate about this author is her consistent treatment of difficult topics with both a content/trigger warning at the beginning as well as just the general sensitivity in the way they were handled in all her stories. I also liked that the D/s topic was discussed among the male characters in terms of consent, safety and what is and isn't a true D/s dynamic along with motivations for entering that type of dynamic and how it's not weird or deviant to like it.
Guaranteed HEA with no cliffhangers for our hero/heroine. No cheating or other woman plotlines or anything like that.
Tropes/Themes Include: Enemies-to-Lovers, Workplace Romance, light Reverse Grumpy/Sunshine dynamic, light BDSM awakening
- Reviewed in the United States on April 12, 2025I love finding a well written and edited story addressing serious situations while holding onto entertainment value. This one is right there: Alzheimer's, trafficking, personal conflict. Honest words.
Highly recommended.
If I ever gave 5 stars, this one would be a candidate for it.

4.5 stars for story / 5 stars for performance
I have not read anything from this author before, so I obviously have not read any of the other books in the series. That did not play a factor at all in the experience. Of course, it was so, so good that I will be rectifying this issue as soon as possible. The writing here was so clever with hilarious one-liners and witty banter that had me (literally) laughing out loud. It was amazing how she was able to weave such fun and light-hearted moments in the midst of a very serious, suspense laden plot. The main characters were so perfect for each other, both with alpha personalities that melded so well with each other. I absolutely loved every side character as well and it was so nice to get the little hints on possible future stories.
As good as this story was on its own, the audio aspect ratcheted up the total experience of this book exponentially. I pride myself on being able to listen to any audiobook with little reaction but that was not the case with this one. These narrators performed the heck out of this book! The smallest nuances brought so much emotion to these performances...joy, frustration, sadness and more...it all came out it spades. The humor in the writing was delivered perfectly and the moments when the 4th wall is broken brought an extra layer of fun. I highly recommend this one on audio.

It’s book four in the Redleg Security series. You can read the HEA as a standalone, but Redleg Security & the suspense plot themes are interconnected.
Rating: ⭐️⭐️⭐️⭐️⭐️ (0-5)
Steam: 🔥🔥🔥🔥🔥 (0-5) public places, toys, mild BDSM, lots of delicious details
Narration: 🎧🎧🎧🎧🎧 (0-5)
Overall: 🌟🌟🌟🌟🌟 (I’d give it 6 or 10 if I could—ALL the shiny stars!)
What I’m Starry-Eyed Over:
🎧 The narrators smashingly bring out all the feelings in this one—sweet, feisty, sad, sensual, sympathetic, scared, and so very stimulated! And, yeah, every time they said stud, Tiger, good girl, cake, etc I definitely melted!
🤩 One-night stand, enemies-to-lovers, workplace romance.
🤩 My favorite part (of the whole series) is how funny and s3xy the MCs are even though some of the topics are serious and heart-wrenching. Truly ALL the feels.
🤩 Cool captivation—it feels so natural and smooth how Jackie captures our attention with an enticing plot and scrumptious characters.
🤩 Cal Klein is totally my newest book boyfriend—he loves with his whole mind, soul, and body.
🤩 Cake on her mind—I love how Mia is obsessed with cake and Cal’s “cakey tush.”
🤩 The suspense and mystery of the storyline is fantastic. That “need to know” kind of feeling.
🤩 New word of the book: bjology. You must like some kinky to enjoy this one, friends.
🤩 Stud, tiger, good girl—I’m melting. These nicknames really work on me.
🤩 These two MCs are strong and determined on their own, but together they help each other become the best versions of themselves.
🤩 Beautiful and loving representation of caring for a parent with dementia.
🤩 Impressive theme of fighting the good fight against human trafficking.
🤩 The whole Redleg Security series has the best found-family and work family vibes.
What I’m Wishing/Dizzy About:
💫 Nothing at all.

5.0 out of 5 stars Soft n sweet n strategically spicy
As always, Jackie Walker has written a light hearted treasure to appreciate.
The pace is well managed, the relationships are authentic & the plot isn't overblown for the sake of drama - when it could have so easily been.
Without giving too much away, watching an adorable, cinnamon roll MC couple discover & wrestle with a new aspects to their individual human experiences is a delight.

4.0 out of 5 stars They complete each other is all areas 😘
I enjoyed this story, like the other Redleg Security books but my only complaint was the length of the book. Some of the chapters were unnecessary, detailing some bit of background story whilst in other chapters the background story was expertly summarised and woven well into the plot.
Other than that, I loved this broken badass CIA agent and her sweetheart of a ex- Ranger making the world and their lives a better place for finding each other. Such a sweet story of fire meeting ice and making a sexy, warm lagoon of unconditional love, friendship and spice! Loved the interaction and side stories from the other characters and sarcastic humour. Great story with just enough angst and a HEA. Enjoy!

4.0 out of 5 stars ...
Check the triggers before reading.
What happens when you come face to face with the girl that snuck out on you after an amazing night together, but she just so happens to be the new hacker that stole your promotion!
Damn Klein! 🔥 'I volunteer as tribute' 😅
So so so spicy!
Dom Klein is addictive but so is sweet Cal. Best of both worlds!
This book loves to tease you slowly, giving you a taste then pulling it just out reach, leaving you frustrated.
But stick with it you'll get the ultimate release your soul is craving.
