Fake dating the man I've loved since I was sixteen to escape my stalker ex? Sounds exactly like something that would happen to me.

Jennifer Blakely had done the work. She'd made peace with her best friend Adam leaving, first for college and then the NFL. She'd learned to live with the years apart and the feelings she'd had to hide — tucked away so carefully she'd almost believed they were gone. When he returns to their Pennsylvania hometown, eight years of careful convincing unravels in a single look.

The timing couldn't be worse. The Mayor's son, her ex, has been leaving voicemails she's too scared to delete, showing up in places he shouldn't, and looking at her like she's something he owns. But in a town his father controls with an iron fist, no one ever steps in to stop him.

No one… except Adam.

Jennifer would find it a lot easier to say no if she didn't still have feelings for him.

Adam spent eight years avoiding her to try and bury the feelings he had for her. Coming home was supposed to clear his head, to help him decide the next phase of his career and yeah — to see Jennifer. Instead, he finds her constantly looking over her shoulder and pretending she's fine when he knows she is anything but. After seeing her ex, protecting his person became his sole purpose. Keeping her close was the only thing that made sense.

He wasn't prepared for how fast being by her side became something he didn't want to give up.

Her ex is watching. And he is running out of patience.

The danger is real. So are the feelings. And they are running out of reasons to keep saying it's all pretend.

Some books entertain you. Others stay with you long after you’ve turned the final page. Hearts on the Line is one of those books.

R. Katze tells a powerful story filled with hope, resilience, and healing. The emotional depth feels incredibly authentic, and that’s because it is. Knowing the author drew from her own experience with domestic violence made every chapter hit even harder. It takes immense courage to transform personal pain into a story that may help others feel seen, understood, or less alone.

The romance never overshadows the healing journey. Instead, it grows alongside it, creating a relationship built on trust, patience, and genuine care. That balance made this story feel both heartfelt and real. Yes, there were tears…

More than anything, I want to applaud R. Katze for sharing something so personal. Stories like this matter. They create conversations, raise awareness, and remind us that there is life beyond survival.

ARC ⭐️3.75 or 4

I thoroughly enjoyed this read and i’m very grateful that I got the opportunity to read it as an arc. I could go on and on about how much I loved the mmc and fmc’s dynamic and just everything in this book but I would be here literally all day. I think the fact I finished this in a day should show how much I enjoyed this. They were so freaking cute and i’d love if there were more books coming to turn this into a standalone series.

The only reason I didn’t rate this higher is because I don’t think the third pov writing style is for me, but that shows that even though that did deter me at first and it may put you off too that you can look past that because the rest of the book was so enjoyable.

This book was just so out of my normal reading tropes, but i’m so glad I gave it a chance, because I loved every minute of it.
And you should give it a chance too when it releases on JULY 14TH🤍

“You can still count on me to keep your ego in check.” 
“Yeah” Adam slowed, the soft pressure of his hand making her turn to face him. “You always were the better part of me.”

~

“No, he never got her… but fuck, sometimes he wished he had been brave enough to try.”

~

“He would hold her for as long as she let him and wish for even longer.”

~

“Jen: Come over?
Adam: Is that really even a question?

It wasn’t, and they both knew it. Wild horses couldn’t keep him from getting to her.”

~

"Life is full of what-ifs…You can't escape them; you can only choose which ones you want to live with.”

~

“Yes, Jen, I love you. I’ve loved you since we were kids; first as friends, now as my everything.”

~

“He glanced back at the stands to see her eyes on him as she smiled. He wasn’t sure how life could get more perfect than it was right then, but he looked forward to seeing it try.”

Adam & Jennifer haven't spoken in years. After he left their hometown and became a football player and she became a teacher, career wise they were on totally different paths. And it just led to a disconnection between them.

But with Adam now being back home for a few months while he makes some decisions regarding his career, he and Jen reconnect, but the Jen he once knew isn't the same, there is fear lurking around and he will do everything possible to keep her safe and...make her his once and for all.

The friendships, not only between the main characters but the townspeople was amazing and I loved it.

Jen & Adam got to not only know each other again, but the mature and independent versions as well.

It was a slow burn, the banter and easy going friendship with the underlying chemistry was written well. The pain and fear the female lead experienced had me in my feelings, but I loved her strength and determination.

Overall, a good and quick small town read.

Thank you to booksiren & the author for an eARC.

Hearts on the Line by R. Katze.

Hearts on the Line by R. Katze is a contemporary romance about darkness, hope, strength, tragedy, and survival, told through the eyes of a caretaker. It follows high school English teacher Jennifer “Jen” Blakely and professional football player Adam Thompson as he battles career and personal demons. Set in a Pennsylvania town marked by corruption, the story centers on tenderness, reconnection, pain, abuse, and injustice.

R. Katze’s Hearts on the Line is far from your average romance. It presents readers with a stark reality and makes its central concern clear: love unfolds alongside domestic violence and systemic corruption.

The true strength of Hearts on the Line lies in the way R. Katze develops and celebrates the characters. Jen rises above the typical damaged feminist trope and works to reclaim her own authority and autonomy, even as oppression and violence press down on her. Adam’s character arc is just as potent, moving from a high school football star to a man at the crossroads of his life, career, and identity, where his fortitude is tested; loyalty matters, and his athleticism is surpassed by deeper qualities.

The chemistry soda between our MMC and the FMC is cutting and can trip, and years of backstories for Jen and Adam continue to work wonders behind them, adding depth to their romance as it begins unfolding. I adored their exchange on childhood and marriage as adults — it remains poignant without tread but not a cliché. The overlap where those two former lovers reach into one another and see what they've both become is warm, tense, and painfully real.

What truly sets this book apart is its exploration of domestic violence and the dark underbelly of local politics. At first, readers who expect a simpler answer may wonder why Jen is not doing more. But while the writing lays bare corrupt law enforcement, victim-blaming, and manipulation, it also threads hope through community support and the protagonist learning to stand up for herself, even if some readers may question its harshness.

At once accessible and haunted, Shoreton Point springs to life with just the right amount of tension throughout. Meanwhile, the light they chase through the shadows, along with small-town camaraderie and festival scenes, softens the novel's darker themes, proving once again that people are greater than the dark in their midst when they gather courage together.

The slow unfolding of the story balances exposition, self-reflection, and action sequences between Erick and his father, as well as quiet conversations with Jen and Adam. In turn, it gives us enough football details without overwhelming those unfamiliar with the sport.

I loved how this story tackles such heavy material with sincerity, and yet the drama can feel overwhelming, particularly for readers looking for a lighter romance. This story moves from romance to suspense to social commentary, which may feel demanding for some readers at times. Readers seeking a feel-good romance may not be ready for the uncomfortable truths within the pages of this book.

Also, the romance's transition from friends to an over-the-top best-friends-who-fall-in-love dynamic, with full physical contact, happens very quickly at the end. The stories threaded through the buildup are deeply emotional, but the more explicit intimacy scenes are highly detailed and may feel extreme to some, even if they fit the story’s intensity.

Hearts on the Line is a thrilling, agonizing, and finally affirming departure from standard contemporary romance. R. Katze gets under the skin with a compelling romance driven by a strong social imperative, and the novel presents conflict through very human characters who are imperfect yet resilient, even as its intensity may be too much for readers seeking something lighter.

I recommend this book to readers who like their romance with a bit of grit, a story where people admit their vulnerability, wrestle with hard issues until they can no more, and then lean into the safe haven offered by love and friendship. This is a story for readers of drama grounded in reality, place, and sincere love, though it may not satisfy those seeking a lighter escape.

If you dislike emotional or social-style topics, this novel may come across as weighty. However, readers ready to follow the fight for justice and love will find great value in this reading.

That, at its core, is what Hearts on the Line asks: How far would we go to protect those who threaten our hearts? And can there be regeneration, even rebirth, after the darkest storms?

Adam Thompson, the local NFL hero, comes back home to consider his options before making a big career decision. He’s stayed away from home for a while, and things around here have changed. Including his childhood best friend, Jen Blakely.
Coming home means dealing with feelings that have been buried for years and learning that life can still surprise you, that being strong isn’t something you have to do alone, but that sometimes it takes a whole village.



I’ve been disheartened by FM romances for quite a while now, so I’m not going to lie, I went into this ARC a little apprehensive. I’m happy to say it turned out to be exactly what the doctor ordered!
This is a story written with love and respect for its characters. At no point did I feel frustrated by the kind of random and nonsensical decisions that so often I find in FM romances. Instead, I enjoyed every minute of it. It wasn't always an easy story, but I thought it handled its more difficult situations with care and sensitivity.

Some of the sweeter moments reminded me of Love Among Thieves and it is the kind of romance I’ve really been missing in FM books.

I read this shortly after Home Ice, a book I really struggled with. (If I had read "my best friend" one more time, I was convinced I was going to lose it!)
What R. Katze does so well here is understand how relationships actually work. She takes the time to rebuild an authentic connection between two people who have always loved each other, but who don't really know each other anymore. The attraction has never disappeared, but Adam and Jen have to learn how to communicate again.
In many ways, it reminded me of Finest Kind of Fate, where the characters recognize that time has changed them both. They don't fall in love with old memories of who they were, but they get to know who the other person has become and choose to fall in love all over again.


Another aspect I really appreciated was the way the book approached some particularly difficult topics, especially . Too often, books take the easy route: they simply tell that someone went to therapy for a while, got better, and move on. R. Katze digs a little deeper into what reclaiming your life can actually look like, while still keeping the overall tone of the story light.
I would have liked a few moments to be developed a little further, and I wish some of the emotional situations had been explored deeper. That said, I understand this is meant to be a lighter romance.


The only thing that really didn't work for me was the number of editing mistakes. There were quite a few spelling, wording, and punctuation errors. Since this was an ARC, I know it isn't the final version, but I was still unpleasantly surprised that more of them hadn't been caught before it was sent out.


Overall, this is a story I'll remember fondly and an author I'll definitely be coming back to.

4,5/5. Suspensful and sweet in the right places.

Overall, a very even experience - started out well and followed through.

The book covers some very heavy topics (DV), but does it very tastefully, in my opinion, so that it doesn’t feel like just a plot device for easy drama. Yes, it drives the plot forward, but it's given a lot of page time to focus on the feelings of victims and how it's never their fault and they deserve their happiness. I really enjoyed how much thought and empathy was put into it.

The tension was there in the right places - both as chemistry between the characters and when shit went down. The couple has an easy rhythm and their banter and constant touching were cute. You could clearly see that they’re comfortable with each other and it allowed you to fully accept the ending as something natural for them. When the drama happened, the book became gripping and your nerves were strained thinking to what extent things would escalate before someone steps in. Good stuff.

Also, I’m a sucker for when people come together to stand up for someone, so when the town backs her up and helps her with her opressor, of course, I couldn't help feeling satisfied.

The side characters are an added element that I really liked. The parents, the agent, the sports people, even the villains. Thoroughly enjoyable.

When it comes to the issues I've had, there are very few I've had with the actual text.

There was one spice scene right after the first one which I thought made everything sound repetitive and felt like an unnecessary addition. It wasn't needed, sounded very close to the previous one, and occurred in too quick a succession. It's a good scene, but it wasn't the place for it.

And I don’t know if it’s something with the file or my Kindle being a little menace, but every time I started a new chapter, it send me back to the trigger warning. It was annoying as hell, because I had to pay attention to the chapters I was in at all times, and that slowed me down.

In conclusion, I do recommend giving it a read, especially if you can handle some heaviness and want to see men punished for their actions. It really speaks to my vindictiveness.

Thank you to NetGalley, the publisher, and the author for letting me read the ARC!

Thank you so much to R. Katze for a copy of this ARC in exchange for an honest review.

~ Summary ~
Childhood friends Jen and Adam were once inseparable, but life pulled them in different directions. Jen still lives in their small town working as a high school teacher, but life has taken an unexpected turn that has her trying to escape an abusive ex who also lives in the same town. Adam, an NFL star, returns to town facing a major career decision. When Adam steps in to protect her, their old bond sparks into something deeper, and he suggests they pretend to date to discourage her ex from continuing to stalk her.
But her ex’s threats loom large, and the small-town police force offers Jennifer little help. As she fights for her safety, Adam is forced to choose between ambition and the love of his life. Together, they navigate danger, second chances, and the kind of love that refuses to back down.


~ Thoughts ~
When given the chance to read a new romantic suspense novel, I will always say yes, so when I was given the chance to read an ARC of this book, I jumped at the chance. This story pulled me in from the beginning and never let go. This had the perfect blend of small-town charm and romance mixed with the tension of an abusive ex who wouldn’t leave her alone. It drove me crazy how anytime she tried to get help from the police or anyone official in town, she was stopped every time.
I immediately fell in love with Jen and Adam together, and he was a great protective MMC. I also think the author handled the domestic abuse storyline well. I also appreciated that the romance began after she had already left her abuser. The balance between romance and suspense was perfect, and I didn’t want to put this down for a second.
This was the perfect small-town romantic suspense novel I didn’t know I needed.

Hearts on the Line is written by R. Katze. Thank you to the author for the opportunity to read this ARC. I have read previous books by her and I enjoyed them. This story is definitely on the sweeter side. A great palate cleanser if you have been reading a lot of dark or dangerous romance novels and need a break. This book does have some triggers of heavier topics. I would advise that you check them out before reading this story.

R. Katze wrote this book with care and consideration regarding the topics discussed throughout. It felt genuine and showed she thought about how she wanted to portray the difficult situations. This small town/second chance romance was full of chemistry, tension, and yearning. There is something special about two people who have known each other forever to come to the realization that they care much deeper than on a friendship level. I fell in love with Adam and the way that he cared for Jen. Adam is the quintessential golden retriever with a heavy dash of protectiveness. Jennifer is the all-American school teacher that needs a little protection. She also needed a little help getting back to the person she once was. They were both very relatable and lovable characters.

These two were the best of friends from the beginning and just needed that little push over the edge to dive a little deeper together. The town that they live in surely helped and approved of Jen and Adam FINALLY making it official. This story is everything I need right now. A reminder that there is still goodness in the world. The story gave me all good feels, laughs, gasps, and feet kicking vibes. I would not mind revisiting this town and these characters. Some of the side characters have the potential for their own great love story.

Thank you to @netgalley and @author_r_katze for the opportunity to read this book as an ARC. This review is voluntary.

Hearts on the Line is a story of strength, love and resilience set in small town Shoreton Point.
Two best friends since childhood, fall back into the easy rhythm of life after years apart. Except it’s not so easy, Jen has a secret that she struggles to share and no one’s talking.

It’s been a while since I have read a book that has evoked such a wide and strong range of emotions. I thoroughly enjoyed envisioning Jen slowly beginning to lengthen her spine as she grew more confident advocating and standing up for her herself. With Adam’s unwavering love and support, Jen refuses to back down. I couldn’t have been more proud of a fictional character. I felt like I was cheering her on every step of the way! Adam was a steady and strong character throughout this whole story and complimented Jen to a T.

Eric is an infuriating character, one that made me need to step away from the book a few times due to anger. A sleezeball that R. Katze put effort into betraying the true nature of what these people are like. If I was capable of running someone over with my car, he would be one character I’d want to take out. He evoked THAT much emotion from me.

Based on emotion alone, I would give this book ⭐️⭐️⭐️⭐️⭐️‘s.

A heartwarming read. This book had the friends to lovers, he falls first, small town vibes! Adam and Jen were best friends from childhood but they drifted apart as they got older and specially when Adam made it to the NFL and moved. They both had feelings for one another but because they didn’t want to risk the chancing of ruining the friendship (yes cue Taylor swift’s song) in pursuit of more they never made any advancements. In light of a situation happening with Jen, they agree to fake date for her protection.

This book touches on sensitive topics, so please do read the trigger warnings. The way it was executed was done so well. Jen is a sunshine but she’s also a strong survivor. It was moving to watch her gain the courage to stand up for herself and see the community come together to stand by her.

Adam is a golden retriever. He’s protective, supportive and a gentleman. The way he portrays his love and care for Jen is so cute!!

If you are itching for a quick read that has the friends to lovers, small town, he falls first, fake dating and a dash of sports romance, check this one out.

Thank you R. Katze for the opportunity to read an ARC.

I am absolutely loving this series! Best friends to lovers has always been one of my favorite romance tropes, and this book reminded me exactly why. There is just something so special about watching two people who already know each other so well finally realize they’re meant to be together, and Adam and Jen’s story delivered that perfectly.

Before anything else, I do want to mention that this book covers some heavier topics, so I definitely recommend checking the trigger warnings before diving in. The author handles these moments with care, and while they add emotional depth to the story, it’s always good to know what you’re going into.

Now… Adam.

Can we all agree that he is the definition of a golden retriever book boyfriend? He is sweet, caring, supportive, and so incredibly lovable. The way he loves Jen and always wants what’s best for her completely melted my heart. He’s the kind of MMC who makes you smile every time he shows up on the page because his heart is just so genuine.

And Jen was the perfect match for him. I loved watching her relationship with Adam evolve from friendship into something so much deeper. Their history together made every romantic moment feel even more meaningful because there was already so much trust, comfort, and love between them. Their chemistry felt effortless, and it was impossible not to root for them.

The small-town atmosphere was another one of my favorite parts of the book. It had all the cozy, close-knit vibes that make this trope so much fun. Everyone knew everyone, everyone had an opinion, and the whole town was so invested in Adam and Jen’s relationship that it had me laughing more than once.

And let’s talk about the bets!

The entire town placing bets and getting involved in their relationship was absolutely hilarious. Those moments added so much humor and charm to the story and made the town feel like a character in its own right. It brought such a fun, lighthearted energy that balanced the more emotional moments perfectly.

Overall, this was a heartwarming, emotional, and incredibly sweet romance with two characters I couldn’t help but fall in love with. Adam and Jen’s journey was everything I wanted from a best friends-to-lovers story, and the small-town charm, lovable characters, and laugh-out-loud moments made it even better.

If you love best friends to lovers, golden retriever MMCs, small-town romances, and stories with plenty of heart, this is definitely one to add to your TBR. I absolutely adored it!

This was an easy, somewhat slow read that I enjoyed but didn't like enough to want to read more by this author. My biggest issue with the book was the dialogue. It was extremely distracting how infrequently the characters used contractions while they were speaking. I'm not usually really particular about that kind of issue, but it happened so often that it couldn't be ignored. The lack of contractions made the character interactions feel so stiff and unnatural, and it just immediately took me out of the story every time it happened.

The characters were the high point for me. Adam was sweet and protective, and Jennifer was a strong, yet vulnerable heroine. Their relationship was loving and tender, even with rather mediocre chemistry. The small-town feel of the novel allowed for a family-focused story with an emphasis on relationships over success. However, I wish the danger with the stalker ex had been resolved differently. There was so much buildup, and I was disappointed with how easily it was tied in a bow.

Overall, this was a romantic, low-stakes book. I recommend it to those who really enjoy sports or second chance tropes. *I received an advance review copy for free, and I am leaving this review voluntarily.*

Fake dating her childhood best friend and long time secret crush, what could go wrong?? Jennifer Blakely made her peace with her best friend, Adam, leaving for college and ultimately the NFL. 8 years of hiding her feelings comes crashing down when he returns home to visit. On top of that, her ex, which happens to be the mayors son is leaving her voicemails, following her, and acting like he owns her. Despite what he’s done to her, no one stands up to him…no one except for Adam. He’s also spent 8 years burying his feelings for her. He’s supposed to be home to clear his head and decide where he wants to take his NFL career. Protecting Jennifer seemed to be exactly where he was supposed to be and having her by his side is the only thing that made sense. Danger is real and near. Adam has a decision to make. How long can they both pretend that their feelings for each other are fake?


Adam is in my new top five book boyfriends! Protective in all the right ways, comforting, smart, loving. Jennifer is also one of my favorite female characters! She doesn’t back down from a fight while also trying to protect those around her. You could instantly sense the chemistry between the two and were rooting for them the entire time! Their communication is top notch throughout the story. Neither of them want to ruin their friendship, especially after missing out on 8 years with one another, and you could just feel the yearning from them both. I laughed, smiled, cried, and got angry. The side characters added balance and layers to the story. I absolutely devoured this book. It was such a good read! I cannot recommend it enough!

I love a story where the main characters know each other so well that their friendship provides a strong foundation for their relationship. That is certainly the case with Adam and Jennifer. The author pulls you into their world, and it's easy to become invested in their journey as they finally take the leap from friendship to something more.

The plot dynamic involving Jennifer's ex adds another layer of depth to the story. The author's portrayal of their past relationship feels authentic and believable, giving Jennifer's emotional journey greater impact. Adam's response to the situation only makes him more endearing, as his actions and unwavering support highlight the strength of his character and deepen your appreciation for him.

Adam and Jennifer will steal your heart with their relationship journey. Their connection feels genuine, their chemistry is intense, and at times the romance is undeniably hot. This is the kind of love story that leaves you so satisfied that it immediately earns a place on your reread list.

Advanced reader copy:

Thank you to the author and Twisted Chaos PR Team for the opportunity to be one of the first to read this book in exchange for my honest review.

**Trigger warning** This books speaks of domestic abuse but not by the MMC

This is a best friend to lovers, second chance, small town romance. Adam moved away to play pro football and lost touch with Jen until he comes home to make a life changing decision. They reconnect as friends but it is obvious that he has always been in love with her, and she him, but has no idea what she’s been through while they were apart.

I devoured this book in a day as I did not want to put it down. The secret love these two have for each other was refreshing but sometimes aggravating as it was so obvious, in a good way. You get so wrapped up in the characters and story that you feel like you could almost walk up to them and say “hey you dummies get it together” LOL.

All in all this was a very good read and I will be adding the authors other books to my TBR.

Thank you to R. Katze and their team for providing me with an ARC of Hearts on the Line.

Hearts on the Line is a sweet small-town romance that combines friends-to-lovers with fake dating, two tropes that work well together. The story follows Jennifer as she returns home and comes face to face with Adam, her childhood crush, after years apart. As they reconnect, their relationship develops through plenty of heartwarming and tender moments, along with revelations from his time away.

I enjoyed watching the characters grow throughout the story, and there were some genuinely sweet scenes that made their romance easy to root for.

My only personal drawback was the writing style. The story is told in third person, and I tend to connect more with romances written in first person, so I found it a little harder to immerse myself. That said, this is purely a matter of personal preference and didn't detract from the story's overall charm.

Overall, if you enjoy small-town romances with friends-to-lovers, fake dating, and a wholesome, feel-good romance,

*ARC
A friends-to-lovers, 2nd chance, fake dating, small town, sports romance that follows Adam, a NFL player who returns home to think things through and Jen, a english teacher and best friend of Adam since childhood.

Adam is fiercely protective of Jen, especially after learning what happened to Jen during the time he was gone. The pair decides to fake date in order to get Jen's crazy stalker ex to back off. It is not a easy feat though, as Jen's ex is the son of the mayor, who is constantly pulling strings for him and excusing his behavior.

This book tells the story of Adam and Jen while also talking about a heavy topic. It shows Jen's healing journey after her ex has finally gotten what he deserves and how she has many people who are willing to help her. I enjoyed reading this book though I wished it would not have been in 3rd person, as I found it harder to connect as deeply with the characters.

Thank you to Netgalley, R. Katze, and the Publisher for this ARC in exchange for a honest review.

Jen Blakely y Adam Thompson crecieron juntos. Fueron mejores amigos durante años y sin darse cuenta, la amistad empezó a convertirse en algo más. Ninguno se atrevió a confesar lo que sentía por miedo a perder su amistad1, así que ambos guardaron silencio.

La universidad los llevó por caminos distintos. Al principio hicieron lo posible por mantenerse en contacto, pero el tiempo, la distancia y las responsabilidades terminaron alejándolos hasta convertirlos en dos completos desconocidos.

Años después, Adam regresa a su pueblo para tomar una de las decisiones más importantes de su vida. Reencontrarse con Jen le recuerda todo lo que dejó atrás, aunque también descubre que ella ya no es la misma. Hay algo que la atormenta y que amenaza con separarlos una vez más. Ahora deberán averiguar si todavía existe una oportunidad para recuperar lo que perdieron o si algunas historias están destinadas a quedarse sin final.


:::

Podría parecer exagerada la situación de Jen, pero solo basta con ver las noticias y ver como muchas mujeres que sufren violencia domestica no son tomadas en serio. Muchos casos llegan hasta la muerte de la victima porque las autoridades no tomaron enserio su denuncia.


Thanks to NetGalley, the publisher and the author for the ARC in exchange for an honest opinion.

Adam and Jennifer’s story is a tale told many times…
Childhood friends, unrequited love, unrealised love, and a smidge of mutual pining…
He comes to town while making a decision about his career, and reconnects with his childhood friend, and realises that he wants more….
This is complicated by the fact that she’s a little annoyed that he ghosted her, and she has an ex who is conveniently deaf to the word no, and has no idea what the law is (or boundaries).
This has some heavy triggers… DV, manipulation, corruption, coercion, public violence, so take care if these are an issue for you.

I did feel that Jennifer and Adam reconnected a little too easily. There wasn’t really anything before that giving any indication of a confrontation or anything. I mean, ghosting your BFF is pretty major…

Overall though, it was a sweet(ish) story, packed full of drama and small town charm. I enjoyed it.

⭐️⭐️⭐️⭐️⭐️

Hearts on the Line was such a heartfelt and charming read. From the very beginning, I found myself completely invested in the characters and their journey. R. Katz does a wonderful job of creating relationships that feel genuine, allowing every emotional moment to land with real impact.

One of my favorite aspects of this book was the balance between humor and vulnerability. It had plenty of lighthearted moments that made me smile, but it also explored themes of love, healing, and finding where you truly belong with so much heart. The character development was beautifully done, making it impossible not to root for them every step of the way.

This is the kind of story that reminds you why character-driven romances are so special. If you’re looking for a book with emotional depth, memorable characters, and a romance that leaves you feeling warm long after you’ve finished, I would absolutely recommend Hearts on the Line.

Thank you NetGalley for the opportunity to review this book before release!!
This book was everything I needed!!

Jen (FMC) is just a girl who is trying to hide from the worst ex a girl could ask for. But is also trying to show that he isn't going to stop her from being... well... a normal human being.
Adam (MMC) is a pro-football star who is coming back home for a few weeks to decide what he wants to do next season.
These two were besties (who may or may not have fallen for each other in high school, but never said anything) and sadly lost connection after high school. Well he's back in town and just so happens to run into her!

The rekindling of these two was amazing. The way he ends up sticking up for her due to her obnoxious ex and his family. They were meant to be.
I love a good found family romance and this is the one!! With some yummy friends to lovers, fake dating troupes in here too.

Don't worry, it does get spicy at the end when they FINALLY admit their feelings!!

Hearts on the Line by R Katze is an emotional, heartwarming romance that skillfully blended the beloved friends-to-lovers and fake-dating tropes into a compelling story of healing, trust, and second chances. Set in the backdrop of a small town, we get to follow the story of the FMC Jennifer Blakely, a teacher trying to rebuild her life and the MMC Adam Thompson, an NFL player and her childhood best friend. One of the things that stood out to me about this novel was the relationship between Jennifer and Adam. Their shared history gave their romance an authenticity that made every interaction meaningful. Overall, Hearts on the Line was a touching contemporary romance that delivered lovable characters, heartfelt emotion, genuine chemistry, and a satisfying happily-ever-after.

I received an ARC copy from NetGalley. Thank you so much for giving me a chance to read and voluntarily review this novel!

This was a really good book based on two main characters - Adam (who has left town to play football) and Jennifer who has stayed in their hometown.
If you have any domestic violence / stalking triggers, this book is not for you.
Adam and Jennifer were each other's best friends growing up but when Adam leaves town, they communicated less and less untill there was no communication.
Adam comes back to town and realizes that he still has the same feelings for Jennifer. Jennifer is a different person now due to her experiences she has had whilst Adam was away and she is scared.
Things escalate with Jennifer's ex boyfriend (where the triggers come in) and Adam realizes that Jennifer needs him to protect her from the ex boyfriend.
But Adam has to make a decision about his career. What decision does he make? Do they end up together? So many questions.....if you want the answers you had better read this book!

Jen and Adam have been best friends since they were 5 years old, but when Adam goes off to college and starts playing pro football, they fell out of touch. Adam is back and their chemistry and affection picks right back up where they left all those years ago. Jen has had a traumatic year trying to heal from the trauma her ex, the mayor's son inflicted on her. Adam is a protector and will do anything to keep Jen safe. As they begin a fake dating scheme to deflect Jen's ex, feelings some into play and the people of their small town are all too happy to win their bets about Adam and Jen finally getting together.

In this small town the mayor pulls all the strings, and Jen has to fight for her rights and safety from her ex. This story is about perseverance, healing, and finding support in the right people. I loved the found family, mental, emotional, and physical health representation, and truth of going after what is right.

Thank you to NetGalley, the author, and publisher for a read of Hearts on the Line. I enjoyed this story and the how well sensitive topics were handled with such care. It had humor, spice, a protective and cinnamon roll of a man down bad for his girl, and a strong FMC. Definitely worth the read!

This was my first time reading this author and it was a good introduction to their writing style and character development.

There are some tougher subjects covered in this book—-DV—-so be aware of any triggers you might have before reading. The author does handle these subjects with care and understanding.

Jennifer had a lot of growth to make during the course of the story. It was interesting to see the relationship develop between herself and Adam. There were some sweet moments that made you root for her and Adam.

If you like a small-town romance where what starts out as fake dating between 2 friends turns into something more, give this title a chance.

The only thing that kept this from being 5⭐️ was that it’s written in 3rd person and I don’t engage as much with 3rd person vs dual 1st person. Just me personally.

⭐Review: 4.4/5

Hearts on the Line by R. Katze was an emotional and heartwarming story that beautifully balanced heavier themes with romance and comfort.

The fake dating and friends-to-lovers tropes were done really well. Watching Jennifer and Adam slowly find their way back to each other was one of my favourite parts of the story. Their history together made their bond feel natural, and their chemistry made it easy to root for them from the beginning.

The story also handles Jennifer's struggles and healing journey with care, while Adam's protective nature adds an extra layer to their relationship without diminishing Jennifer's strength as a character.

Overall, this is a great pick for readers who enjoy fake dating, friends-to-lovers, small-town romance, and protective heroes.

“Fake dating the man I’ve loved since I was sixteen to escape my stalker ex? Sounds exactly like something that would happen to me.”

If you’re looking for a quick read that is fun with slight suspense, you should check out Hearts On the Line. It’s a small town, fake dating to escape a stalker ex romance, where the MMC happens to be her childhood best friend and now a pro football player.

There are a lot of sweet and tender moments, as well has spice. The dynamic of the main characters is one of the better representations of childhood friends to lovers I’ve seen in a long time.

Thank you to R. Katze and Twisted Chaos PR for letting me read an arc of Hearts On the Line. All thoughts are my own.

***This book deals with domestic violence, please check your triggers.
Jen and Adam have been friends since childhood but drifted apart in college. When Adam comes back to town, they rekindle their friendship and start to fake date to protect Jen from her abusive ex.

This was a solid romance novel. Loved Jen and Adam and their friendship. Loved the town and the side characters. The domestic violence aspect of the book was treated with care and respect, and it was described enough to make you understand what she went through without feeling like you are reading a tabloid.

This was my first book by R. Katze, and I’m looking forward to reading her other books.
