Beautiful
Format: Kindle
I love omegaverses I had looked at this one multiple times thinking it's just another book about cocky rock star guys that let fame get to their heads and there are parts like that so I wasn't 100% off. I started reading the second book and met the fmc Astraea from the first one,after she had a run in with the aphla from the gym.😁 it gave me the push to stop and read book one first and im so glad I did this book was amazing their was so many characters I fell in love with hoping they will find their happily ever after. the guys were great, the plot was 🎯, and the ending had me 😭😭😭. I was wondering how nate could ever redeem himself, and he did. the last scene with him was sad, but I also felt it was beautiful. thank you to the author for making a beautiful omegaverse book that gave me all the feels. now I'm jumping straight into book two.

Knot their Omega
Format: Kindle
It took me a day to really get into the book, there is a lot happening in the beginning of the story. I wish there was more of a time frame because I felt like something’s happened quickly but they were farther away than I thought so that was a little confusing to me. I felt like there was so much happening but also not enough.
As for the story itself I enjoyed it, it was different than other OV I’ve read. Bring the tissues, you will need them. They guys were great, I wish we saw more of Kai and Kenjis relationship. As for Nate…… IYKYK.
I enjoyed this book, my first from this author and look forward to reading about Kamaris story.
Book: ⭐️⭐️⭐️⭐️/5
Spice: 🌶️.5/5

Has Potential, Poorly Executed
Format: Kindle
I really really wanted to enjoy this book and was looking forward to reading it. However there were just one too many convoluted plot points, sentences just did not flow nicely at times, and I was left with a lot of confusion on my end. I think it has the bones of being a great story but seems like it was rushed and I had to push myself to finish the last of the book and was left with an unsatisfying ending. It’s definitely different from other omegaverse novels I’ve read but not for good reasons. I really think it could be great but needs some serious tweaking and editing before I’d read it again.

Secrets, Seduction, and Rockstars!
Format: Kindle
Rockstars, secrets, and off-the-charts chemistry? Sign me up!
Cinder Blaze takes us on a rollercoaster of passion and peril with Knot Their Omega. Blair Vesper, a secret Omega masquerading as an Alpha, strikes a risky deal to tour with Blooming Salvation, a band teetering on the edge of chaos. Enter Icarus Morrigan, the enigmatic manager, and his three complicated and irresistibly sexy rockstars: wild Kenji, icy Kaiser, and fiery Nathaniel.
This book delivers steamy Omegaverse drama, sizzling slow-burn romance, and just the right dash of angst. The tension between Blair and the band crackles like electricity onstage, while the societal stakes add depth to the spicy dynamics.
Short, sharp, and oh-so-sinful Knot Their Omega will have you hooked from the first note!
