The BANTER 😍
Format: Kindle
Thoroughly enjoyed this book. The perfect witty, banter-laden escape, even if predictable for me, which isn’t even that part of the comfort and fun?

okay
Format: Kindle
I’m honestly not sure how i finished this book. i considered dnf-ing multiple times due to boredom, and then did that cycle like 5 times??? So here are your stars, i guess.
The plot is bonkers, and somehow was still sooooooo boring to me. Every single twist was painfully obvious, and the chemistry between Tansy and Gemma was saccharine in a very cloying way. The best way i can think to describe this book is having a trope wheel in front of you, spin it 5 times, and write that down.
I didn’t hate my reading experience, but i also didn’t *enjoy* it.

Another Fantastic Story From Alexandria Bellefleur
Format: Kindle
Love this author so much that I THOUGHT I had pre-ordered this book. Now I'm late to the party, but realizing that this book had been released made my day yesterday. Less than 24 hours later, I've finished the book and I miss it already.
In my opinion, Bellefleur is damn good at writing romances that feel like they could be real. That's not to say they aren't swoonworthy - they definitely are - but she finds the romance in the everyday instead of relying on overly flowery declarations and grand gestures. Okay, fine, there are some grand gestures, but it's the combination with the little things that make her love stories so great.
A couple quick additional things I will say about Bellefleur's writing at this story:
- She stays true to her characters. They change and grow, but they do so in a way that fits them or aligns with the influence of their partner. I also appreciate the fact that her characters don't talk and act the same way from book to book. Each character feels like someone new to get to know.
- The spicy scenes are - *chef's kiss* - practically perfect. A good amount of scenes with a good amount of words dedicated to each without any cringeworthy metaphors.

Cute!
Format: Kindle
This was really cute but once I got to around 60-70% I felt like the story dragged and it took me much longer to finish this than was necessary. Also idk if it was me, but for some reason the way the characters talked at times reminded me of a Historical Romance novel and it had me ???
Still a good time and I'm glad I read it :)

One of my all time favorites!
Format: Kindle
This is one that I love to reread every now and then. The character building is unparalleled and the chemistry and banter between Tansy and Gemma is electric. I’m almost nervous to read some of her other books due to the fear they won’t live up to this one! 10/10
