    Book Info

    Title: Sienna Rossi: Beyond Shattered Trust (The Rossi Legacies Book 9)

    Author:  Moonlight Muse

    Publication Date: August 31, 2026

    Category: Paranormal Fantasy Romance

    Relationship: This book features a fated mates M/F relationship between a werewolf (Jayce) and werewolf/demon/witch (Sienna/Mordana)

    POV: Told from the POV of multiple characters with the majority being both the male and female main characters

    Series or Stand-Alone: This is a book that is part of a The Rossi Legacies series set in the same universe of The Power of Bonds Saga also by Moonlight Muse.

    I feel it is best if you read the series from the beginning for better understanding of the characters and overall storyline.

    Length: Long - 416 pages

    Ending: Ends with a HEA and satisfying conclusion for our couple while the overall story in this series will continue on.

    Overall Rating: 4 out of 5 stars

    Open or Closed Door: Open door

    Spice Level: 3.5 out of 5 peppers - There are several detailed spicy scenes that feature dirty talk. 

    The book is more plot driven with some smut sprinkled in.

    Age Range: Jayce is said to now be 21, which would make Sienna around 20.

    Book Boyfriend Material: If you read the previous books, you know by now Jayce has had more than his fair share of hurt. As such, he has become colder and more standoff-ish.

    However, that doesn't mean he isn't still caring and there for those that are important to him, even if he doesn't always make that crystal clear.

    FMC: Sienna has certainly matured a bit after everything she's been through.

    That said, she still loves hard and will not stand by idly as life passes her by. She's wiling to own up to her mistakes and fight for what she wants and thinks is right in life.

    Readability: Easy to read and flows well with minimal grammatical issues. Some wording issues that personally gave me the ick that I'll detail below.

    Main Themes/Tropes: Betrayed ex lovers; fated mates; forced proximity

    Author’s Supplied Triggers: None provided

    Available On:

    Please note that the availability options listed were applicable at the time this review was written but may change over time.

    Synopsis From Author

    A king who wishes to shield his heart, and a queen who will stop at nothing to fix what she has destroyed.

    Sienna Rossi made one choice.
    A choice born from love, desperation, and the fragile hope that she could save the man she could not live without. But some decisions come with consequences that even love cannot soften, and the mistake she made has shattered the trust between her and the alpha she loves beyond anything she ever feared.

    Jayce Westwood has always been a man of control - ruthless, powerful and unyielding. He was born to lead, born to protect, and born to carry the weight of a crown that was never meant to be gentle. But when the consequences of Sienna’s actions break him, even the Deimos King begins to question what remains of a bond built on pain, secrets and betrayal.

    Sienna will stop at nothing to fix what she destroyed, and Jayce will do everything in his power to shield what little remains of his heart.
    But darkness is rising, the enemy is moving, and the threat in a land far away is growing.
    Despite the aftermath of past actions, the love between them still remains.

    In a story of shattered trust, devastating choices, dangerous power, and a love that refuses to die, will Sienna and Jayce find their way back to one another?
    Or has one mistake finally broken what fate itself once bound?

    My Review

    I've been eager to read this book ever since the seventh in the series was released almost a year ago. I was not disappointed.

    Likes

    • The story draws you in from the beginning
    • Even though longer, I did not get bored thanks to all the twists and turns
    • Really enjoyed the character growth and maturation

    Dislikes

    • Some wording used gave me the ick
    • Has one of my least favorite tropes

    First I will definitely recommend that you start at the beginning of this series for things to make the most sense and know why some of the side characters in this book make the choices they do.

    I will admit that as much as I enjoy them over all, it sometimes takes me several chapters to get into Muse's books. That was not the case with this particular book.

    I was hooked from the start and there was so much action and twists that I wanted to keep reading and thus finished it faster than I normally would.

    I really enjoyed how Sienna and Jayce had matured and evolved. In some ways they've switched roles from their first book with Sienna being the more grounded one and Jayce having to deal with more grief, emotions, and insecurities.

    And what Sienna ultimately does to show just how much she trusts Jayce...wow.

    The overall story and conflict that has spanned the series was just as entertaining to read as the parts with our main characters. Muse did a really great job building suspense and writing the action scenes.

    There are also several spicy scenes if that's something you enjoy reading in your romance books.

    Normally I'd want to rate a book 5 stars when it's one that has me so enthralled I can't put it down. But a couple of things derailed that for me.

    First, I didn't realize until reading this book that someone described as doing something hornily would give me the ick and make me pause to cringe. But it does, and was used a few times in the book. Maybe that makes me petty but we all have our quirks.

    Secondly, this book uses one of my least favorite tropes. Jayce basically lets Sienna think that it's her fault they're not together now that she's back but you'll find out that's not what the real issue is.

    While I can understand where Jayce is coming from in this instance, and I know they're popular tropes, miscommunication and lying by omission always make books a bit less enjoyable for me.

    That said, I definitely really enjoyed this book and recommend it to any romance book lovers - just make sure you start at the beginning of the series .
