**A Riveting and Emotionally Charged Journey**
"Unwanted" by Sirena Song is an absolute masterpiece that grips you from the very first page and doesn't let go. The storytelling is impeccable, weaving together a tapestry of raw emotion, suspense, and heart-wrenching beauty. Song's ability to delve deep into the psyche of her characters makes them come alive, making you feel their pain, joy, and struggles as if they were your own.
The plot is brilliantly crafted, full of unexpected twists and turns that keep you on the edge of your seat. Each chapter unfolds like a piece of a complex puzzle, gradually revealing the depth of the narrative. The themes of love, rejection, and redemption are explored with such nuance and sensitivity that it leaves a lasting impact.
Sirena Song's prose is poetic and evocative, painting vivid pictures with her words and creating an immersive reading experience. The character development is outstanding, making it easy to become emotionally invested in their journeys. The ending is both satisfying and thought-provoking, leaving you pondering long after you've turned the last page.
"Unwanted" is not just a book; it's an experience that touches the soul. I highly recommend it to anyone looking for a powerful and unforgettable read. Sirena Song has truly outdone herself with this one.

Totally Sweet
Format: Kindle
🔥OmegaVerse
🔥Single Mom
🔥Scent Match
🔥Emotional Trauma
Well written, emotional omegaverse about a single mom of 2 with an ex-Alpha boyfriend that found his Omega and ditched his family. Cammie has a meet cute with Reid and Finton separately but they both find her to be their scent match.
This book is totally sweet with lots of drama but lots of proving to Cammie that she is loved and wanted.
My Personal Ratings:
5 Stars: Loved it! Couldn’t put it down or obsessed about it while needing to get to the end of it. Had to share some bits with my hubby!! Usually read in less than 2 days cause a girl has got to sleep sometime. Will be reading everything this author has to offer and most likely reread the series as next books in the series are released.
4 Stars: Really Good. Whether the story drew me in or a specific character, will definitely continue the series and look into more books by this author.
3 Stars: Enjoyed something about the book, whether it be the storyline or a character but also may have not liked something. Sometimes the book is great but needs some TLC from an editor. May or may not continue the series.

Read it!!! It's so good!
Format: Kindle
I will reccomend this book to anyone and everyone who is looking for an omegaverse book to read! The rabbit hole of male omega books this one sent my mood reading self down was crazy! 🤭 I could not have loved Finn more! He was the sweetest omega, making sure Cammie was comfortable each step of building a relationship with him and Reid. He was so good with the kids even though Ben was a little rough around the edges.
Cammie's fears were all justified but the way she learned to trust her new pack was sweet! They just continued to show up and her sister was hilarious! Being a mom and thinking of her littles but also finding her own happiness was such a sweet journey for her 💖 lets just talk about the kids for a second and say Em is a spitfire and I LOVE her and Ben sweet Ben just wants to protect his Mama but needs love, Reid does such a good job stepping up!
And the 'gift' at the end had me in tears!! 🥹 Without giving too much away that is why I think sweet Finn is my favorite of all male omegas I have ever read! His way with words no matter what he is using them for, declarations of love, pep talks, or advice he really just knows what needs to be said 💖

I wanted to like this more than I did
Format: Kindle
This started off so well! I thought it was going to take Lola on a run for her money but it ended up getting weird. I liked the writing but there was just too much spice which I didn't think was possible for me. There were too many times that the writing felt weird or the situations too outlandish and unrealistic. I had to skim through a lot of the later half. It might just be the dynamic between the characters that didn't work for me so I'll give this author another go.

love love love!!
Format: Kindle
Unwanted is the perfect hurt/comfort romance read. I LOVE an OV romance where the beta is the center of the story and Song delivers a heartfelt story of a single mom to 2, burned by her alpha-hole ex starting her life over in the small town of Knotty Pines. Reid and Finn are an alpha/omega pair who’ve been together since they scent matched as teenagers, they’ve always known someone was missing in their lives and they’ll stop at nothing to prove to Cammie that her, Em & Ben are everything they always wanted.
I couldn’t put this one down - Song tugs at your heart strings, and gives you vulnerable, real and lovable characters with depth and relatability. The book is so well paced, detailed to perfection without overdoing it or straying, I really honestly loved the flow and details in this story and the banter and humor had me smiling throughout this read. This was the perfect hurt/comfort, who did this to you, fated mates, stop at nothing to get the girl romance that I’ll be recommending for the foreseeable future!!
