Review: Aether Guardian (The Mark of Shadows) by Joshua Bush

May 24, 2026 by A S Colworth Leave a Comment

Rating: 7.5/10

Synopsis

Liberation. Loyalty. Light.

Enter the world of Aether Guardian with the first book of a stunning fantasy series. This tale of magic and danger is perfect for fans of John Flanagan, Christopher Paolini, and Joseph Delaney.

Her power could save the world—if it doesn’t destroy her first.

In the city of Erebus, young women are trained for ten years to become Sisters—elite warriors wielding Aether to protect humanity from the monstrous beasts that roam beyond the city walls. For Cecilia, it’s a chance to prove her worth. But when her Soul Stone awakens with a forbidden Aether, everything changes.

Branded a heretic. Distrusted by her team. Feared by the very institution that trained her.

Assigned to a squad that barely tolerates her presence, Cecilia must survive grueling missions, master a power no one understands, and unravel the truth behind the High Church’s hidden agendas. As beasts begin to breach the city’s defenses and ancient enemies stir in the shadows, Cecilia and her squad are thrust into a battle far beyond what they trained for.

The world doesn’t want her. But it just might need her.

Review

I’ll start by saying I’m generally not a huge hard magic system person. I understand the appeal, but personally I prefer magic to feel a little more mysterious and unknowable. Here, the magic is very structured and mathematical. Some readers will absolutely love that level of detail. Others, maybe not as much (Brandon Sanderson has made a whole career on it).

At first, I honestly wasn’t sure this book was going to click with me. Cecilia didn’t immediately grab me, and some of the early dialogue felt a little unnatural. Lines like: “Ever since my mother brought me to this city as a baby, this day joining the sisterhood has meant everything to me” stood out in a way that pulled me out of the story a bit.

But somewhere along the way, the book really found its footing and pulled me in. The worldbuilding became the big standout for me, especially the monsters, which were easily my favourite part of the whole thing. There’s a real sense of danger and mystery around them, and honestly I wanted even more.

Cecilia’s journey toward self-confidence worked well too. Watching her struggle to learn alongside the other students while slowly realising her abilities don’t function the same way was compelling, especially once the story started revealing why. Trying not to spoil anything there, because that aspect becomes much more interesting as the book goes on.

Some side characters worked better for me than others. Lucy and Diana in particular really tested my patience. They felt very much like “standard fantasy bullies,” and after a while it became obvious their main role was to highlight how different Cecilia is.

Still, this is a really solid debut. If you love hard magic systems, I can see this being a huge hit for you. And even if you’re more like me and lean toward character-driven fantasy, there’s still a lot here to enjoy. Especially if the promise of cool monsters gets your attention as quickly as it got mine.

About A S Colworth

Once upon a time, I thought writing a fantasy novel would be a noble, maybe even romantic pursuit. That illusion shattered around chapter three. Now I’m the proud (and slightly haunted) author of Dreams of the Fallen — a dark fantasy full of prophecy, betrayal, and characters who need therapy.

When I’m not wrestling my own writing into submission, I’m reading anything with doomed worlds, morally questionable choices, and ancient magic no one fully understands. Or I’m roped into my wife’s animal collecting hobby and can be seen walking (wrestling) a deranged Dalmatian and a terrier around the countryside.
