A Book That Lit Up My Heart
I’m always on the hunt for a romantasy that sweeps me off my feet, and A Dawn of Onyx by Kate Golden did just that. Released in 2023, this debut novel whisked me into a world of magic, danger, and a romance that had me blushing. If you’re a fan of A Court of Mist and Fury or crave a story with a strong heroine and a brooding hero, this one’s a gem. In this review, I’ll share why A Dawn of Onyx is so captivating and who’ll fall under its spell.
What’s the Story?
Set in the war-torn kingdom of Amber, A Dawn of Onyx follows Arwen Valondale, a healer who’s just trying to keep her family safe. When she’s captured by enemy soldiers and taken to Onyx, a rival kingdom ruled by the mysterious King Kane, her life flips upside down. Arwen’s forced to use her healing skills in Onyx’s court, but as she gets closer to Kane, she uncovers secrets about him—and herself—that change everything. Their slow-burn romance unfolds against a backdrop of political intrigue and magical battles, keeping you hooked without giving too much away.
The world Golden creates feels so real. Amber’s golden fields and Onyx’s shadowy castles popped off the page, making me want to wander through them. As someone who loves cozy fantasy vibes, I was all in for the mix of warm healing scenes and dark court drama.
Why It’s Amazing
Golden’s writing is smooth and addictive, like sipping hot cocoa on a chilly night. Arwen is a heroine I cheered for—kind but fierce, with a backbone that shines when she’s pushed. Kane, the king with a hidden soft side, is pure heartthrob material, and their chemistry sizzles without rushing into anything too steamy. The romance builds slowly, with longing looks and witty banter that had me smiling ear to ear.
The plot’s a perfect balance of heart and action. There’s enough magic—think glowing spells and ancient artifacts—to thrill fantasy fans, plus court schemes that keep you guessing. I loved how the story touches on themes like trust and sacrifice. In 2025, when we’re all juggling tough choices, Arwen’s struggle to protect her loved ones felt so relatable. The world’s diversity, with characters from different lands, adds a fresh layer to the genre.
Any Weak Points?
A Dawn of Onyx isn’t perfect, but it’s close. The first few chapters take time to set up the world, which might feel slow if you want instant action. Some side characters, like Arwen’s allies, could use more depth—I wanted to know them better. The magic system’s cool but a bit vague at times, which left me curious for more details. These are small bumps, though, and didn’t dim my love for the book.
Who Should Grab It?
This book’s a dream for romantasy readers who love slow-burn romance, strong heroines, and lush fantasy worlds. If you’re into The Serpent and the Wings of Night by Carissa Broadbent or Iron Flame by Rebecca Yarros, you’ll adore this. It’s great for anyone who enjoys court intrigue and magical vibes, perfect for ages 14+ due to mild violence and romantic tension. If you prefer fast-paced thrillers, the slower romance might test your patience.
Why It’s a Standout
A Dawn of Onyx sparkles in the romantasy scene because it feels both familiar and new. Golden’s take on a healer-turned-heroine isn’t something you see every day, and her world-building is rich without being overwhelming. BookTok’s been buzzing about this one in 2025, with fans swooning over Kane’s charm. As the first in the Sacred Stones series, it sets up a bigger adventure I’m dying to follow.
My Final Take
A Dawn of Onyx is a magical, romantic escape that’ll steal your heart. Kate Golden weaves a story full of warmth, danger, and chemistry that lingers long after the last page. I give it four out of five stars for its gorgeous world and swoony romance, with a slight dip for the slow start. If you’re ready to lose yourself in Amber and Onyx, this book’s calling your name.
