I absolutely loved the tone and worldbuilding of the book. It reminded me of how people talk about discworld(I've tried a few of them but it never clicked) with it's wacky, not quite serious, fantasy world that is nonetheless full of interesting places and interesting fantasy concepts, as well as the satire of real world concepts.(A futures market for prayers? lmao)
I've seen some reviews complaining about infodumping, but personally I found them a joy to read. Something about the tone and the prose just made it flow really well so it never felt like a chore, and the world is the books best aspect so I was always happy to hear more about it.
The idea of a small time wall-god lucking into a boon that slows the aging of the guardsmen who work on top of him, which turns guardsman into the most wanted job, and leads to the wall being extend and widened to allow more people to work on it, which then snowballs until it turns into an ever growing megastructure that covers most of the continent it's located on is such a cool and unique fantasy city concept.
We spend most of the time inside the Wall, and it's full of interesting locations with history and texture. You can tell the author did a lot of research and had a bunch of ideas he wanted to cram into the book.
He touches on all kinds of stuff from, from economics and ecology, to archeology, and a LOT Of critiscism of the endless growth mindset of our society. It's not very subtle, nor super deep, but I found the ways he weaved it into the worldbuilding and history quite enjoyable to read.
I think my biggest issue with the book is the characters. They're not terrible, nothing like three body problem or anything, but they're just kinda fine. The books feels more like a fast paced romp through interesting locations while the author (mostly through Thea) infodumps about the world and it's history, than a character study.
Oh, and apparently it's a litrpg book? It doesn't really feel like it for most of the time, but there are some similarities. I've not read a lot of litrpg books, on count of most of them being bad, so the only thing I can really compare it to is Dungeon Crawler Carl.
The most obvious similarity is Thea and Aven strategizying about which boon to pick, which feels similar to the lootbox rewards in DCC. There's also the way you channel soulstuff for feeding gods which is similar to the cultivation concept, but there are no explicit levels or anything like in DCC. It also have a few "Oh we just did something, time to pick our loot" moments. I didn't mind the litrpg moments, but it wasn't really the draw for me.
TLDR: Not a literally masterpiece, but a really fun read with a very creative and unique world. I feel like I'd wanna play a dnd campaing or bethesda style RPG set in Cambrias' Wall.
