Short, cute, straight to the point
Format: Kindle
This is the type of fast pace stories I love to read. I felt nothing felt incomplete. Everything went together. Loved the men loved the best friend and the Fmc. Definitely would recommend this book.

Fun, Steamy, and Just Enough Depth
Format: Kindle
I liked this book — it was cute, short, and exactly what I expected from a quick Omegaverse read. While it doesn’t dive too deeply into character development, there was enough personality and backstory sprinkled in to keep the relationships believable and engaging, especially given the length.
What I really appreciated was that the focus stayed on the main characters and their connection. The heat, the banter, and the romance were front and center without getting bogged down in unnecessary drama. It made for an easy, enjoyable read that flowed smoothly from start to finish.
I’m looking forward to the next book in the series. There was a teaser blurb at the end, but it isn’t up on Amazon yet — hopefully it’ll be posted soon so I can add it to my wish list.

Good But
Format: Kindle
A little disjointed at times, at least to me. This was about Lila (omega woman) and Harrison, Wesley and River (alpha males). The main characters were likeable, as was Lila's friend, Wendy. Lila finally wised up and left the alpha she had been with for a couple of years because he was an a-hole, who treated and used her horribly. She knew some, if not all, of the guys from college if I remember correctly. The guys had been looking for an omega to bond with for some time. When Lila saw Harrison again, the other two guys were out on a date with another omega but Harrison refused to go because he didn't like her. He saw Lila again and knew she was the omega they had been searching for. However, it wasn't easy for them to convince Lila of that because of the way her ex-alpha treated her.
The sex was hot. There was one inconsistency. I could almost swear that when Lila first saw Harrison again, she told her best friend, Wendy, that Harrison was the lead for his pack. Then later on when she's spending time with River, she thinks he is the pack's lead. Maybe I read something incorrectly. All in all, a good story.

Sweet read
Format: Kindle
A sweet steamy read of an omega who finds her worth and finds the guys that are willing to show her. The story had lovable characters with low angst and a HEA.
