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.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book.
Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray.
I wish it had been proofread - there are a lot of typos, but nothing too distracting.

Madison Deserved Better
Format: Kindle
Madison was a beta...except she wasn't any longer. She was a late presenting Omega. And she was struggling. She was tall and thin, not tiny and curvy. She was opinionated. She was everything an Omega was not. After suffering through her first heat, her friends took her to Ardor, a club where Omegas came to safely find Alphas. She's not expecting much but then she connects with a sexy beta. And when she meets his Alphas, they set her body on fire. Maybe, she's found her no-strings-attached heat pack. Maybe, she's found something more.
I could not connect with the characters in this book, so their story never resonated with me. And there was no love story; there was sex. Grey made it clear from the beginning that he had a true love and it was his beta boy, Rian. He went so far as to reassure Rian “Say the word, I’ll never touch her again. Lucas can put the babies in her. I only need you, beta boy”. So, Madison was there for babies, no emotions needed. Nice. No, thank you. I want the Omega to be the center of their world, not an incubator. Lucas and Rian weren't any better. After her heat, they let her leave. Not one of them made her feel valued. No one gave her a reason to stay or even offered a cuddle. And the sex didn't even come across as mind-blowing. Madison deserved better.
