I backed the Kickstarter and followed the development of this game. This won't be an in depth review so much as an overview of what to expect to help decide if you might be interested.
First, I really like the setting and the art. That's what drew me to the game in the first place and what makes it stick out.
It's a Fate Core game with a setting largely based on Native American stories (particularly Lakota, I think), with a strong dose of other, mostly tribal, cultures.
The cosmology is really cool. It takes Native American themes and weaves them into a mythic, high fantasy setting with strong horror elements.
The PCs are definitely intended to be heroic and make a difference. You can help a town avoid literally being lost to sorrow, or run a zombie apocalypse-style game of survival horror as shivers threaten to overrun everything, or get involved in rebellions against an oppressive regime in cities built on the back of giant turtles, or investigate and heal a tear in reality that's letting inhuman Breachers through, or go on an epic quest to save the world (the Trail of Slumbers described in the book could easily be an epic, mythic campaign), and so on.
The game is pretty straight-forward Fate Core. If you like Fate Core, then you'll like this. If you don't, then nothing here will change your mind. There are a few minor system variations (like Power Levels and a magic system), but it's pretty close to Core mechanically.
The magic system walks a line between too much and too little detail (and different people will have differing opinions how well it succeeded). Mechanically, most of the system is about how you cast, depending on your tradition. The effects of the magic mostly come down to the four core actions. But the traditions and also the Mysteries are evocative and also allow a very wide range of possible character concepts.
Hopefully this gives you a better idea if you might be interested.
