real good
Format: Kindle
This was a solid read for the ABO universe. The characters are great. The smut scenes were well written. And the town is so cute I want to go there. It didn’t have much character development it just felt like I was getting to the characters as they were getting to know each other.

So sweet
Format: Kindle
It’s so unexpectedly sweet that it sneaks up on you. Each character is so unique and charming. I love the openness and honesty among their pack. It really blows me away how wonderful this omegaverse trope plays out. I received a free copy of this book and am voluntarily leaving a review.

Needs editing
Format: Kindle
Cute storyline and promising characters, but the lack of editing is painful to read. I would love to read an edited version.

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it. I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!. I received a free copy of this book and am voluntarily leaving a review.
