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!

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot.
Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable.
The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold.
The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.
