A Dawn of Onyx by Kate Golden – Is It Worth the Hype?

This post may contain affiliate links. Disclosure here.

I bought this entire trilogy under the best possible circumstances: my local Barnes & Noble was closing to move locations, and every book was 50% to 75% off. 

I’d been seeing bits and pieces about the Sacred Stones series floating around the fantasy romance corner of the internet for a while and kept mentally filing it away. 

When I saw all three books sitting there at a steep discount, it felt like a sign. I bought all of them on the spot.

I went in curious but cautious. Discounted impulse buys don’t always pan out. This one did, at least for book one.

Summary

A Dawn of Onyx follows a healer who finds herself in enemy territory, navigating a world of political tension, magic, and a kingdom that isn’t quite what it seems. 

When she’s forced into close proximity with someone she has every reason not to trust, the tension, both the dangerous kind and the very much not dangerous kind, starts to simmer. 

The world is bigger than what we see, and that sense of something larger waiting just beyond the page is what keeps you turning. The stakes feel real, even when the answers don’t come easily.

What I Loved

The world-building genuinely pulled me in. There’s an atmosphere here that made me want to understand the magic system, the politics, the history, all of it. 

It’s the kind of world that feels like it has more going on beneath the surface than any single book could hold, and I mean that as a compliment.

The pacing also worked well for me. There were slower stretches, but nothing that felt like a grind, more like the story catching its breath before pulling you forward again.

And the slow burn. I appreciated that this book actually committed to the slow burn. There’s a moment, I’ll just say the plot very aggressively interrupts what could have been a very different scene, and the restraint there genuinely made me more invested in where things were headed. 

That kind of tension, when it’s done right, is what fantasy romance is built on. This book did it right.

I also finished it and immediately grabbed A Promise of Peridot before I’d processed a single thought. That says something.

What Wasn’t My Favorite

The main character starts strong. She’s trying to escape, listening in on conversations, actively working to figure out what’s going on, and I was rooting for her. But once the romance with Kane kicks in, that drive quietly disappears. 

The curiosity, the urgency, the sense that she’s a person with her own agenda, it fades into the background, and she starts to feel like she’s being written around the plot rather than through it. 

I understand why it happens emotionally, but I kept wanting her to hold onto both things at once. Her character development is genuinely there and I did enjoy watching it unfold. I just wish the consistency had carried through.

The tropes are also well-worn. If you’re newer to fantasy romance, you’ll probably love them, they’re beloved for a reason. 

But as someone who’s read a fair amount in this genre, I found myself wishing the story had leaned harder into what makes its world distinct rather than hitting every familiar beat:

• Enemies to lovers
• He falls first
• Miscommunication
• The chosen one
• Hidden powers
• Forced proximity
• “Who did this to you”
• Morally grey MMC

They’re all here. The execution is fine. It just doesn’t reinvent anything.

I also wanted more from both characters beyond their tragic backstories and a hobby or two. The world has real depth. I wanted the people in it to match.

Vibe Check

Genre: Fantasy Romance

Mood: Slow burn, atmospheric, tension-heavy, occasionally frustrating in the best way

Read if you love: Enemies to lovers, morally grey MMCs, fantasy world-building, restrained romance that makes you want to scream

My rating: 3.5 out of 5 stars

Spice meter: 1 out of 5 chili peppers

Would I Recommend It?

Yes, with context. If you’re newer to fantasy romance and want something with genuine world-building alongside the romance, this is a solid starting point. 

If you’re a seasoned fantasy romance reader who needs something that pushes the genre forward, you might find it a little paint-by-numbers. The world and the slow burn are genuinely good enough to keep you reading. 

The fact that I went straight to book two before I’d even collected my thoughts should tell you something.

Outro

A Dawn of Onyx is not a perfect book, but it does its job: it made me want more. More of the world, more of the characters, more answers to the questions it plants early and waters carefully.

I’ll say this much without spoiling anything, if book one felt like an overdone-but-enjoyable introduction to a fantasy romance world, book two hit me like an emotional gut punch I did not see coming. 

A Promise of Peridot turned up the heat in every sense, and the character development that felt slightly thin in book one starts to really bloom. I have a lot of thoughts. I’ll be back next week to get into it.

In the meantime, have you read the Sacred Stones trilogy? I’d love to know where you landed, especially on book one. Did the tropes bother you or did you lean in?

Looking for a similar vibe? A Kiss of Iron by Clare Sager fits the bill.
