magical realism + sports romance
Format: Paperback
3.75★ sapphic challengers with some ashley poston-esque magical realism! this was a fun twist on the soulmate concept, making them real possibilities for the lucky few born with the name of their marking their wrist. for luca, it's everything she's dreamed of. for juliette, it would only get in the way of her tennis dreams. luca and juliette face off as tennis rivals who also happen to be soulmates. juliette deals w the pressure of being 3rd in a whole family of tennis aficionados while luca deals w her legendary plays as merely "luck". if you really like tennis or the sports aspect of sports romance, this definitely gets into the thick of it. sometimes it was confusing for me as someone who doesn't really know tennis well, but generally, i enjoyed it. The romance was really cute, I did find Juliette a little bit bratty in the beginning (probably deliberate) but there's definitely growth with their relationship. Overall, it was an enjoyable sports romance with a little ✨ an honest arc review ♡

Decent fluffy beach read
Format: Paperback
As a lifelong tennis fan and a queer woman, I was excited to find this book. However, the writing and characterization were not the best and I found the language used to describe the sex scenes pretty distasteful (like something you'd find in a hetero romance novel, I imagine). Nevertheless, I finished the book and it was still a decent fluffy beach read.

Loved it
Format: Kindle
This book was a Rollercoaster of emotions and I was all about it. I love the relationship between Luca and Juliette bc it was real and human. It showed growth, love, and understanding. It wasn't easy but it was real. I enjoyed every moment of it especially the soul marks. That was a wonderful element to the plot that I would love to read more of.

So cute
Format: Paperback
Ok, going into this, I didn't realize this had any fantasy-ish/magical elements, so for a minute, that threw me off. But honestly, I was really pleasantly surprised by this book. I had never heard of Katie Chandler before, but had seen the book mentioned on a list of upcoming releases so I just thought I would give it a try. This is a classic rivals to lovers story and I was here for it! Luca and Juliette were pretty nasty to each other in the beginning so it definitely took a minute for them to come around. I really enjoyed the amount of character growth that happened in this story. Juliette especially comes a long way within herself to be a better person her Luca and for herself. It was definitely a bit of a rollercoaster with the push and pull, but it paid off in the end. The idea of a "fated mates" situation, in a mostly contemporary romance was definitely original and I look forward to seeing how she might incorporate those fantasy elements into future books. 4 stars from me! Great story.
