Set in a world where Hallow is used to access ancestral powers, The Company’s main role is to keep a balance between politics, power and science. I enjoyed the way this book was written, following a noir detective writing style, Tinsley shows us a very rich world where Hallow can both provide power and create dependency. With bootleggers selling Hallow to addicts, The Company must keep control of the streets. This world is rich with description, I did find that there was a lot crammed into this book especially as it’s under 300 pages. However, with that in mind I do think that this is great for readers who like to get into the meat of the story without losing pacing. 

The Hallows is a dark book. It revolves around a magical serum that grants extraordinary powers while slowly destroying the people who rely on it. It also throws religion, addiction, medicine, and corporate control into the mix, and the result is a one bleak story. 

I enjoyed the setting. Tinsley blends noir detective fiction, industrial fantasy, horror, religion, and political intrigue into something fresh. The Providence Company, a corporation that evolved from a church and now controls access to Hallow, is one of the most original fantasy institutions I've come across in a while. Everything about this world feels well thought out, from its social hierarchy to its strange traditions and inhabitants.

The characters are just as memorable. Cam is an excellent protagonist. He's observant, compassionate, and carries the weight of his past without constantly reminding the reader about it. His dry sense of humor provides just enough relief to stop the novel from becoming relentlessly bleak. The supporting cast is equally strong. Daffodil, Forget-Me-Not, June, Mother Ashya, they all feel like people with lives beyond the pages they're on, and several of them stole scenes with surprising ease.

I liked the writing, too. Tinsley rarely stops to explain how everything works, instead letting conversations, investigations, and everyday interactions reveal the world piece by piece. 

All of this is a good thing in my dictionary, but it does make The Hallows a demanding read. There are a lot of concepts, organizations, magical abilities, social groups, and bits of terminology introduced in a relatively short space of time. I was never completely lost, but you need to pay attention from the very beginning, and I suspect some readers will bounce off that density before the story has a chance to show its full hand.

The ending also felt rushed. Most of the novel takes its time building the mystery and exploring its fascinating world, but once the final pieces start falling into place, events move faster than I'd have liked. The conclusion is satisfying, but I couldn't shake the feeling that a few of its biggest moments deserved more space.

Even so, those are relatively minor complaints.

The Hallows isn't afraid to tackle addiction, exploitation, prejudice, identity, and institutional power, yet it never loses sight of its characters. Beneath all the corruption, violence, and body-altering magic is a good story about people trying to do the right thing in a system that rarely rewards them for it.

Overall, I really liked it. It's dark, weird and occasionally pretty disturbing, but the characters and the setting make it worth the effort
