Revolt: The Onyx Mist Series Book 2

Coming August 4, 2026

From Amazon Bestselling author Sara Flanagan comes the second book in the Best of BookTok Onyx Mist Series, a captivating DARK fantasy romance inspired by Aladdin, with a feminine rage twist. Perfect for fans of Raven Kennedy, Sarah J. Maas, Harper L. Woods, and Amber V. Nicole.

“He hoped she saw the final look in his eyes. His promise that, even if death loomed between them, Mora would never be rid of him. Not truly.”

The crown has fallen and Mora falls with it, trapped and cursed in the face of Dother’s death. Unable to escape what he’s done. Stuck with her new Keeper, Castellan, a King's Guard determined to use his wishes to save the Halflings, Mora stands begrudgingly by his side in the face of a revolt... and learns just how monstrous she can be.

In her dreams, she finds solace in the arms of a Fae she should despise, a male who soothes her broken spirit and stokes her desire. All while Zadriel wakes to her scent saturating his clothes. Yearning to be with her yet knowing they can never truly be together.

As Berwick burns, a greater evil looms, and Mora’s royal blood makes her a pawn in a new game of crowns and wishes. A game that demands far more than her cunning. Because saving the Halflings means sacrificing what little freedom she has left, and Mora can’t decide which is more desirable... duty or the ever-tempting lure of her rage.

Revolt is an adult dark fantasy romance and a prequel to Wish. It is intended to be read as the second book in the Onyx Mist Series. This series is full of magic, feminine rage, morally grey characters, and a swoon-worthy fated mates romance, with monstrous villains you’ll wish you could end yourself.

Please Note: Revolt contains mature themes, explicit content, and dark elements. It is intended for an adult audience; read at your own discretion. Trigger warnings are linked in the e-book. This is the second book in a dark fantasy romance series.

  • “You all are not ready for this ride! Revolt has everything Wish had, but also more. More trauma, more feminine rage, more emotional damage, etc. I think this is one of my top reads!”

    Kaitlyn | @kaitlynhillebrand

  • “It was a wild ride. A beautiful gruesome ride, and I loved every second of it ”

    Maryann | @maryannaugerbooks

  • “Sara Flanagan is back at it and she’s on fire! I love a great backstory, and this one highlights all the juicy details leading Mora down her onyx path! Enemies are lovers (but it’s ok because “it’s all a dream”). The villains are even more infuriating, somehow. And hopes are dashed over and over again. What a perfect addition to the series. I loved every page!”

    Mary | @_thebookdragon_

  • “If such a thing is even possible, I loved Revolt even more than Wish. Sara’s writing is so beautiful, her characters so real and relatable that you feel their emotions as your own.”

    Steph | @a__shortcut__to__mushrooms

  • “Revolt is a staggering feat, a breathtaking achievement from Flanagan and a nuanced analysis of trauma, healing, self loathing and fear, wrapped in a story of true love that will beat your heart bloody in the telling of it.”

    Kate | @tothekateswho.read

  • “Sara does a phenomenal job of creating depth, complexity, and structure to her characters while also building fantastical worlds you could get lost in. Revolt is a testament to her commitment to building characters that won’t soon leave you and the depth of love and sadness you thought you could feel go even deeper."

  • "Beautifully written! Revolt is an intense, Dark Fantasy Romance with heart stopping moments. Mora’s Rage is brilliantly crafted in this book, it bridges the gap and painting a full story 300 years prior to Wish’s timeline. If you love soul shattering, lots of yearning and feminine rage, you will love Revolt, part of The Onyx Mist Series! "

    Drita | @drifter.readz

  • "Revolt was an absolutely incredible read! Sara, once again, took us on a roller coaster ride full of emotions and turmoil, but I wouldn't have it any other way. It was tragic and intense, but also sweet with some light hearted moments peppered in. A very easy 10/10."
