Sports Romance at its best!
Format: Kindle
You guys! The way I cheered Iris on throughout this book! When Roman and Iris met will forever be something I laugh about. Absolutely I recommend this book to you! There is plenty of spice too. Not too much, but just enough. We see betrayal, heartbreak, anger, love, pride, self preservation and so much more in this book. Lauren Rowe has very quickly become a top favorite romance author for me. IYKYK! The way she sucks you in and makes you feel like you’re right there within the story, it’s phenomenal.

The audiobook was done right! Narrators Samantha Brentmoor and Aiden Snow were fantastic! I’m not sure a better pairing could have been picked for this book.

Chasing the Ring
Format: Paperback
Chasing the Ring by Lauren Rowe delivers a fun, trope‑heavy sports romance with a jilted bride and NFL quarterback in paradise. While the chemistry between Iris and Roman is charming and the humor lightens the story, the plot feels predictable and the emotional beats don’t land as strongly as expected. A decent, easy read, but nothing that stands out in the crowded contemporary romance field.

A great start to a new series!
Format: Kindle
“What happens in Kauai stays in Kauai”
Iris’ wedding didn’t go as planned when she found out about her fiancé’s lying and cheating ways. She goes to their honeymoon alone where she discovers a handsome stranger in her bungalow, turns out the place was double booked. There was instant attraction between Iris and Roman and after one amazing night together they decided to spend the week with a no strings fling.
As the days go by, it’s starting to feel more and less like a fling. But they’ve both been withholding information from each other to protect their identities and once the secrets come out, they have to figure out if the time they’ve spent together is worth the risk.
I love Iris! I think she’s so relatable. So proud of her for standing up for herself when she found out about her fiancé and for doing what she did when she found out about the truth about Roman. She’s the prefect preschool teacher, sweet, patient and kind. She deserves all the swoon and spice after what she’s been through and Roman definitely delivered.
Roman being in the public eye all the time never knows if someone is being truthful just to get close to him so he definitely embraced the fact that Iris didn’t know who he was. He was able to just be himself and show her his real self. And this man knows how to bring the swoon and he for sure delivered in the bedroom!
Such a great start to the series! This is the Lauren Rowe’s trad debut and she definitely delivered!!! With the Super Bowl coming up soon, this is a must read to get you in the mood!

Excellent Rom-Com
Format: Kindle
Starting with an iconic, unhinged confrontation with a serial cheater! Quickly moving onto two awesome meet cutes. (i guess one of them is a pee-cute)
Iris had a reaction I fully stand behind. I do hate the she went viral for it, but that comes back around to be almost empowering!
I love an unrecognized athlete - secret identity style trope and this one was done well. Giving Iris time to heal up and bask in the attention of a man who sees her as everything she is.
Roman and his family have a great relationship and the way they all came for Iris was perfect.
Magic Blinders really took me! I truly love the concept, how it helped Roman, and how I can see it really helping children and people like me with adhd!
Lauren stories have an interesting structure I have not read anywhere else. They keep me on my toes, laughing til I cry and really just enjoying the stories.
Thanks Lauren and Netgalley.

Football & Romance
Format: Kindle, Format: Kindle
This was such a fun read and also my very first football romance. I was pulled right into the story from the beginning when our bride to be FMC gets shown a secret phone the fiancé was hiding by his own sister! You can bet I was sat after that. I love me an FMC that stands up for herself and promptly serves him up the best revenge in front of the whole church and then takes that honeymoon trip as her own personal vacation.
Enter or MMC Roman who is also on vacation getting a surprise when Iris busts in on him in the shower. I couldn't have laughed harder at the whole situation. Things heat up very quickly between our MCs that will leave you fanning yourself and absolutely swooning. Although Roman starts things out with hiding who he really is from Iris you can't help falling for his charm and sweetness. Also, on a personal note he was a Michigan Wolverine?! Yeah, that's a win in my book. Go Blue!
This book is perfect for those who love a good sports romance especially football. It will also have you smiling like a loon, belly laughing, and kicking your feet. I read the audiobook as well and it made the whole story even greater. Highly recommend.
