I love these books. I love the characters. And I love S. M. Boyce. Seriously. I am Boyce’s biggest fan and she better realize that.
I had high hopes for this book when it came to the series—I was so in love with the first book I didn’t think it could get any better. Boy, was I wrong. Treason went far beyond my expectations.
I was on the edge of my seat and holding my breath at more than one scene… You won’t want to miss this wild ride.
—Heather Sutherlin, author of Light in the Darkness
I didn’t think it was possible for me to like Treason more than the first book, but I do. This series is definitely one of my all-time favorites.
Boyce comes back with book two of the Grimorie Trilogy, and comes back STRONG! I honestly didn’t think Lichgates could be topped on my all-time favorites list. Treason surpassed it with flying colors.
—Robert Zimmermann, author of From Where I Stand
Treason is yet another incredible adventure by the amazingly talented S. M. Boyce.
—Hilary of Novel d’Tales
I have not loved a book, or a series, as much as I loved reading Treason in a long time. There’s something about Boyce’s style of writing that makes you fall into her stories and never want to come out.
—D. Ann of Overflowing Bookshelves Reviews
Once again, Boyce’s writing pulled me in. It’s amazing how such a fantastical world can feel so real and believable.
Adults and teenagers alike would enjoy this novel. There are no sex scenes, basically no bad language, and only positive depictions of making hard life decision the right way. Five stars from me.
—Rosemarie Herbert of The Cosy Dragon
Boyce pens her characters strong and complex but totally believeable in a plot filled with emotion, twists, turns, and with a touch of humor.
I really love Boyce’s writing. It’s clean, polished, and hits the perfect balance between pretty description and succinct action phrasing… She has a knack for painting a picture.

—————-
Kara Magari is about to discover a beautiful world full of terrifying things—Ourea.
Kara, a college student still reeling from her mother’s recent death, has no idea the hidden world of Ourea even exists until a freak storm traps her in a sunken library. With no way out, she opens an ancient book of magic called the Grimoire and unwittingly becomes its master, which means Kara now wields the cursed book’s untamed power. Discovered by Ourea’s royalty, she becomes an unwilling pawn in a generations-old conflict—a war intensified by her arrival. In this world of chilling creatures and betrayal, Kara shouldn’t trust anyone… but she’s being hunted and can’t survive on her own. She drops her guard when Braeden, a native soldier with a dark secret, vows to keep her safe. And though she doesn’t know it, her growing attraction to him may just be her undoing.
For twelve years, Braeden Drakonin has lived a lie. The Grimoire is his one chance at redemption, and it lands in his lap when Kara Magari comes into his life. Though he begins to care for this human girl, there is something he wants more. He wants the Grimoire.
