Intriguing
Format: Kindle
Very interesting world set up! I'm liking the characters more and more as we get to know them as well. At first I found it difficult to remember what powers each of the 3 monsters have, but the author does a great job of working it into the story to help the reader remember and eventually tell who is who much easier.
Seems like a great start to a series. I can't wait to see where everything is heading.

In Love With These Interconnected Series
Format: Kindle
I am in love with these interconnected series!!!! I love getting sneak peeks at the girls we haven’t met yet and seeing the girls we know and love interact with each other. I also really enjoy the concept of how all of the sectors are set up and the way that the academy is run. Alexandra’s situation is especially unique as she has lived her whole life thinking that she is human while wishing that she wasn’t. She has created her own monsters to protect her from the monsters in her real life, but all of the sudden her monsters are real!!! I love how different this is from other stories that I have read, not a lot of characters will living beings with their own memories and thoughts into existence. I am also super excited to see how the ending translates into the next book and if there will be any ties to Greek mythology included.

It’s an experience

⭐⭐⭐⭐⭐
**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.
