Kluvberg #3

Love on the Line

Rate this book
They’ve trained for every challenge ... except each other.

Defense has always been Claire Caldwell’s default setting. Signing with the Boston Siege, her hometown team, was a dream come true. But outside of soccer, her life is slowly falling apart. She’s focused on one making this season—likely her last—count after years of disappointments.

Otto Berger’s life was just upended mid-season. Sidelined for the first time in his career with a serious injury, he winds up thousands of miles from home, face-to-face with a woman he never expected to see again. Assistant coaching for the Siege while recovering sounded simple. Coaching Claire? Complicated.

They’re no longer the young Olympic hopefuls who met in Paris. One walked away without a gold medal. Both left broken-hearted. Neither anticipated being forced to work together years later.

Can two people with a history they can’t escape rewrite their story, or are they doomed to relive the same ending?

"I kiss her before she can say a word, slow and languid. For the first time, it doesn't occur to me that it could be the last time. It feels like a beginning."
I thoroughly enjoyed this. A second-chance, coach/coachee forbidden love sports romance? Couldn't go wrong.

Claire and Otto meet at the Paris Olympics when they're in their early 20s- they immediately hit it off and fell hard, only to go their separate ways after the games. We got some flashback scenes from Paris and I think they worked well to show us the depth of their feelings and how quickly everything happened but also didn't overwhelm the story. Cut to six years later and Otto moved to Boston to be the temporary new coach for Claire's team, while he recovers from an injury.

I loved how even when these two were trying to avoid each other and stay out of each other's way they were just so drawn together. Like they couldn't help but gravitate towards each other. I loved how they supported and cheered each other on, and how they understood each other in a way only professional athletes could.

As always I wish we had gotten more domestic scenes. Even after Otto and Claire admit that those feelings from Paris are still there and maybe even stronger than ever, they resist each other. I wish we had gotten to see them just be together a little more.

📖 Favourite Quote: "I was not ready for us in Paris, Claire. I wanted to be, but I was not. I am now."
📚 Would I recommend? yes!
💬 tldr thoughts: a swoony second chance romance!

In the package:
📦 second chance
📦 it's always been you
📦 assistant coach x player
📦 dual timeline

Plot: Claire and Otto first met 6 years ago at the Paris Olympics where they both played soccer. Fast forward to the present and Claire's life outside of soccer is tough and Otto has just agreed to become an assistant coach to Claire's team after a serious injury. Can they make it work this time?

Thoughts: you guys know I am a sucker for dual timeline books so I ate this up!! Tbh all second chance romance books should be told through dual timelines because it just works. This is my first book by C.W. Farnsworth and I will have to read her backlog now! I always appreciate books with emotionally complex characters, and Otto and Claire were exactly that. I love their banter and tender moments, and especially the grand gesture towards the end cause who doesn't love that!?

Thank you C.W. Farnsworth for the eARC!

It was heavy. It was emotional. It was funny. It was yearning. It was everything. Farnsworth put love in her writing, just like Otto and Claire did. What a great end to the Kluvberg series.

Fav quote
“He put love on the line, and I want to do the same.”

Fav bromance interaction
“She’s American?”
“So is Saylor.”
Beck scoffs. “I’m aware of my wife’s nationality, Berger.”
I resume staring out the window.

Happy release day to my one of my instant-read authors! Although, I need to re-read the second in the series as I always forget all about it after I’m done

Review of advance copy received from Netgalley

4.5 ⭐

Thank you endlessly to Victory Editing NetGalley and C. W. Farnsworth for the e-arc of Love on the Line in exchange for an honest review. All opinions expressed are entirely my own.

I have been desperate for my next C. W. Farnsworth fix while I wait for the release of Cruel Summer, because her books are dangerously addictive. I imagine this must be what taking drugs feels like because the inexplicable high I get every time I read one of her books should probably be studied.

To anyone new here, I will read absolutely anything Charlotte publishes, and you can probably find me somewhere screaming about how much I love her books; probably on my Instagram page. I don't know how she does it, but her writing has me in an unrelenting chokehold, and honestly, I'm not mad about it. This final instalment in the Kluvberg series definitely doesn't disappoint; Otto and Claire's second chance at love was such a joy to read.

A chance encounter ensues where Otto and Claire meet at the Paris Olympics that they're both competing in. Their connection was instant and their chemistry blossomed into something really tender and beautiful, though it came to an abrupt end because of their geographical distance of living on opposite sides of the world. Fast forward six years later, Otto finds himself recovering from an injury that means he cannot do the one thing he loves; play football, and relocating to Boston and assisting the women's football team as their assistant coach; the same team Claire plays for.

What I love most about this series is the focus on female athletes. Women's football (I'm with Otto on this one; we call it football in Europe) in books is almost unheard of, and Saylor was the first book that I read about a female athlete that played football, and professionally, too.

I loved the flashbacks to Paris and seeing how Otto and Claire first met. Their connection sparked immediately, and in the present, you can feel the lingering emotions they still carry while navigating the challenge of working together.

Both Otto and Claire are interesting, emotionally complex characters. Otto’s early life was marked by emotional neglect: his parents were absent, and the grandfather who raised him was largely disengaged and unsupportive of his football career. Claire harbours strong resentment toward her father, who divorced her mother, and she is also caring for her mother, who is suffering from dementia. She feels stuck and has fallen out of love with football.

It isn’t until Otto returns to her life and begins working with the team, offering his support, that Claire starts to fall in love with the sport again. Even though they try to resist their attraction, they are still faced with the same challenges they had six years ago, with both of their lives on different continents. What I love most about Charlotte’s writing is the journey and character development for both characters. Claire, who was initially adamant about keeping her father out of her life, learns to accept his support, allowing him to help with her mother’s medical bills and be there for her as a father again. Otto’s journey is a little different: having missed out on getting the  girl the first time, he is determined not to let their second chance slip away, and relocates to play in the States.

Despite their many hurdles they face, I couldn't help but root for them. I absolutely loved seeing some old faces again; Beck and Saylor and Will and Sophia, even Tripp, Will's brother.

Otto and Claire's story was a sweet end to the Kluvberg series. It was a beautiful mix of romance, personal growth, and second chances.

Tropes

celebrity romance

4.5 ⭐️
What a lovely read! You’ve got Claire, the strong female lead, and Otto her “right person, wrong time” second chance at love in a player coach, forced proximity situation.

I gobbled up this book pretty quick and immediately went and purchased the other books in this series.

The soccer aspect was also fun and different for me. It felt very fitting given that it’s about to be the World Cup!

It was giving Saylor & Beck but reverse lol but I fear no one can take their place

Would have been a 5 star for me had be not been a total manwhore (bc of course he was) and I wish he didn’t get engaged to someone else during their separation (idc if it was 6 years, of course all claire had was a lackluster bf)

Also I feel like there weren’t that many scenes of the two together to show them falling in love again ??? Like they barely spent any one on one time that would warrant them being totally in love - at least they had Paris but it was 6 years ago !!!

There is a reason football/ soccer is called the king of all sports and i feel like this book really does justice in showing the pressure to achieve perfection and the close up every player faces when it comes to small mistakes or even actions after you win something.
It is incredibly well written in regards to this part.
And talk about a second chance, since one of the Olympics is over I really felt the same way i did during it, the vibes are just something else, and to read the past with those kind of vibes and feelings, really upgraded the book to a different standard.
Make Otto a stay at home husband!!!! I absolutely love Otto and Claire, they complete each other in a way we rarely get to see and read.
And the found family, the cute nephew, is just another bonus to this story.

I really loved this one. The emotional tension between Claire and Otto grabbed me right away, and you can feel all the history sitting between them in every scene. The story nails how hard it is to face someone who once knew you better than anyone else, and their connection feels quiet, painful, and very real. I also loved how the sports setting adds pressure without taking over the story. The romance is slow, emotional, and full of heart, and the healing felt so satisfying by the end. I enjoyed it.

Read count: 2

CW Farnsworth is an author I will FOREVER read and I know there is a very high chance that I'll love anything she releases. Whether it's a book about professional athletes, famous musicians, small towns, billionaires - her range never fails to impress me.

I'm not going to lie, I enjoyed the first 2 books in this series, but they really can't compare to this one! I loved getting to know Otto in the previous stories and the fact that he is part of a second chance, dual timeline, HEA was so exciting.

This story gives me such Kulti vibes (which is another one of my favorite books of all time) in the best way! We have a German professional soccer star, turned coach of a professional women's soccer team in the US. Their relationship has complicated history and now add in the fact that he is her coach- I enjoyed every chapter. This will be another CW book that I know I'll reread over and over again.

Things I loved:
- seeing all angles of the story with dual timelines and dual POV
- quite a few cameos from the past couples
- how their relationship in both past and present timelines were kept to themselves
- both of them working through complicated family relationships
- seeing moments of jealousy from both MCs
- the scene when Claire gets hurt during a game and Otto rushes to her side.... melt

Thank you so much to NetGalley for the advance copy! I'm so grateful!

All is good until the one person who never should’ve been back in your life shows up again. And this second chance between Claire and Otto was so freaking good!! CW knew just what she was doing with this one.

Claire never thought Otto would turn up in her life again after they left each other in Paris knowing there could be no future for the 2 of them half way across the world. Now Otto shows up as a coach, back in her life, just dumped there being this temptation from the past. But Claire has her family to think of. A sister, who is a single mom to her nephew back in town. A mom that needs full time care, and a dad she hasn’t talked to much since her parents divorce. The last thing she needs is Otto to come back and complicate her life. Claire just wants to continue to play soccer and do it without the burden of losing another huge game that defines her life. Now if only Otto would take the hint and make sure that his presence doesn’t make a distraction so she can focus on what needs to be focused on.

Otto knew his life was gonna change when he took the job in Boston to coach the women’s soccer team during his rehab of his arm after his surgery. Now, Otto knows showing up unannounced probably isn’t the best thing to do when seeing someone who hasn’t left his mind in a really long time. It’s also the fact that he doesn’t know how Claire is going to respond to seeing him again after he broke her heart. He didn’t expect a warm welcome however he also didn’t expect Claire to be stand offish to him. With life still at home in Kluvberg, and not really getting anywhere with Claire, Otto realizes maybe he should just finish the season and go home without making a distraction of himself. However, Claire does start to thaw out a little bit and Otto realizes that maybe their fling didn’t freeze in Paris all those years ago. Maybe something is still there and they were meant to find each other again.

We adore a second chance romance and add in a man that has yearned for years, you have me hooked. CW really knows how to make me fall for these men, and all those men have is their women on their minds. I’ll never get tired of reading every second of these books.

I can’t tell you the last time I read a soccer romance! And I feel like now I need to read more!

*an important note if you follow what I read, you know that dementia and Alzheimer’s can be triggers for me and this book does have a side character with dementia. It was done in a way where we aren’t spending oodles of time with that character but more seeing the repercussions and effects on the MCs story and so it didn’t bother me

Okay, now that that’s been said- I thought this was really cute! It was one of those stories that you just get lost in and a few hours later, it’s done and you’re feeling satisfied.

Claire and Otto have history and so we get dual timeline and I found myself eager to go back to the past to see what happened between them.

You also get:
-second chance romance
-right person, wrong time
-forced proximity
-player x coach

This is also book 3 in the series (I haven’t read 1 and 2 yet) and I’m happy to report that you can absolutely read this independent of the series. If anything, it makes me interested to go and see who book 1 and 2 follow!

And thank you to C.W. Farnsworth for the early copy!

4.5! I love women’s sport!!! Claire plays for the Boston Siege as well as the U.S Women’s National Team. She had the opportunity to plan for the national team at the Paris Olympics, and during her time in Paris, she had a whirlwind romance with none other than Otto Berger. He is one of the best goalies in the world and was also in Paris for the Olympics. However, when their time in Paris came to an end, so did their relationship. It isn't until Otto shows up in Boston as the new assistant coach for the Siege that they must confront their lingering past.

I honestly just wanted to give Claire the biggest hug. She is a person who cares deeply and feels like she needs to carry the weight of those she loves on her shoulders. It is an incredibly tiring and lonely thing to go through. It was amazing to see her slowly go through the journey of choosing herself and learning how to balance all aspects of her life. Otto's return to her life was definitely a shock for her. I don’t think she ever expected to see him again; however, after realizing he would now be a big part of her life, she slowly learned she needed to resolve their past. I think it also allowed her to heal other relationships in her life.

Otto was such a cutie! After having to take a season off to be able to recover, he decides to take on a new role in a new country. He's definitely in a time of his life that is full of uncertainty, and I believe that drove his uncertainty towards Claire. Nevertheless, that man was so down bad for Claire it was insane. There are two specific things that he does in this book that are my favorite micro tropes in a sports romance that I was genuinely screaming. The story was so well paced, and by the end, I felt that Claire and Otto got the ending they deserved after everything.

Thank you to C.W Farnsworth for this eARC in exchange for an honest review

Only C.W can make football sexy to me.

I adore any and all sports romances Charlotte writes and this one was no different. The yearning, longing and slow burn of Otto and Claire's journey was torturous but in all the right ways.

⚽Second chance/ right person wrong time
☘️Coach x Player
⚽Found Family
☘️Complex family dynamics
⚽Dual Timeline

There is a wonderful focus on female athletes in this book. The community Claire had with her players and the way the coaches and players uplifted each other was really heart-warming to see. Claire's relationship with her sister was really impactful to me and showed that it's not just romantic relationships that can have second chances. I loved the family dynamics throughout this book and it felt very healing and positive.

Do we think their ship name would be Clotto or Ottaire?

Fab read for any lovers of sports romance and the tropes above <3

Claire and Otto meet at the Paris Olympics. He is a superstar German goalie and she is just starting out as an American Defender. He's a celebrity, nobody knows her name. Things don't end the way they both hoped it would. Claire and Otto do not see each other for 6 years and suddenly reunited. He is rehabilitating a shoulder injury and temporarily acting as assistant coach for Claire's professional Boston team. Feelings they have long since buried resurface and they need to decide how to deal with them.

This was my first CW Farnsworth book and I really enjoyed it. I love that this was a sports romance where both characters are athletes. Both want the other to be the best player they can be. I loved seeing Otto and Claire come to terms with their feelings and learn how to support one another. Both grow as individuals and as a couple.

Thank you Entangled publishing for sending this book to me!

I'm extremely lucky to have received an ARC of this book and was not surprised to have not only loved but devoured it.

As per, Charlotte does very well in showcasing her characters and their personalities and how they develop. I am a sucker for second chances but even more so a lover of football, so you can imagine this is a match made in heaven for me!! (not to mention the goosebumps I got when my home city was mentioned???)

Otto might be in my top 3 C.W. Farnsworth book boyfriends. I particularly loved his vulnerability in emotions, particularly how loud (and obvious) his love for Claire was. His immediateness in helping Claire when she lost a precious token sealed the deal for me.

I loved Claire as a FMC. Her tenacity for her sport and the love she has for her family, even if she struggles, at times had me teary. I wouldn't say the book is super angsty, but ohh...it does have its moments! Like Otto, it was clear that Claire was a lost cause the moment Otto came back into her life. It was as if no time had passed despite her clear attempt at resisting the chemistry.

The small moments and buildup to their reconnection always had me on edge, which is why I wish we had more scenes of them together-together. However, the small moments and buildup did enough to suffice my adoration for the couple.

Overall, the book was fast-paced and one I could get through in a couple of hours. It’s my favourite thing about reading Charlotte’s books, it’s plot driven and I never have to worry about tangents or loose plot lines. While this book is a standalone, I would recommend reading the other books in the series first (or just Saylor and Beck’s book because they do heavily appear in this book), but it is not necessary.

Love On The Line is the third book in the Kluvberg series by CW Farnsworth. It's a second-chance sports romance, and it was an amazing read! I love this series, and this one just made me love it even more! I especially love sports romances when both characters are athletes, like they are in this one.

Otto and Claire were everything! I loved how the author flashed back to six years ago when Otto and Claire first met in Paris at the Olympics. The flashbacks really helped me feel their connection, and their chemistry was off the charts, then and now! This one is highly recommended with way more than five stars!

ARC RECEIVED BY AUTHOR

Thank you to CW Farnsworth for the arc of this book! I had such a good time reading it. It was such a cute soccer romance.

It is also my first soccer romance so it was a fun plot line. The characters start at the Olympics where they met 6 years ago and it switches to present where he’s her coach🤭 absolutely loved the second chance romance. Honestly the author did a good job writing these characters and their family issues. I loved the whole story and the way it ended was bittersweet🥹

This was so refreshing and fun! Releasing it after the winter olympics was genius. I really enjoyed the dual pov and the dual timelines. I loved how realistic this story was. People often use the phrase “right person, wrong time” but they are literally that! I loved how self assured Otto was from the beginning he knew what he wanted. His backstory only made me root for him more. I love how Farnsworth explores relationships with loved ones. Otto’s relationship with Opa was very raw and relatable. Same with Claire’s relationships with her dad. They indifferences weren’t ideal but there was always love and i feel like it’s very relatable to family dynamics who shape you into the person you are. I adored their story, I wish we got to see more of them together.

Pro soccer players, second chance, coach and player.

I enjoyed this one. Claire and Otto fell in love swiftly while in Paris for the Olympics but the timing and circumstances weren't right.
6 years later and they're in the same place again and have the opportunity to allow their feelings to grow.

How can you not love a second chance romance?!? Mix it with coach/player and some forced proximity at times… I did not want to put this book down! I loved the dual timeline aspect of the story, that’s how you have to do a second chance romance. I loved the spice and everything else about the plot! I am so glad that we got to see more of Otto Berger, I was intrigued by him from the start of this series and this book did not disappoint! Claire and Otto are everything! They have such good banter and chemistry! I couldn’t stop smiling while reading this!

Claire and Otto met six years ago in Paris, and they haven't forgotten each other since.

When Otto gets injured playing pro soccer, he comes to the US to coach for Claire's team.

I loved the dual timeline, and how their past and present were woven so seamlessly together to make the yearning hit so hard.


Tropes:
Second chance
Former playboy
Forced proximity

Probably would've been 4☆ but books about athletes need more sports for me. Especially when it's women's sports. I felt like there was more of Otto's football than Claire's soccer. Also, I was sad to leave the Kluvberg setting so it lost a bit of the magic there.
