I'd recommend this, but it isn't perfect and it has a lot of unfulfilled potential.
The art is nice to look at, but for all the detail it has, very little is added to the experience. I'd almost say that it's the opposite of One Punch-Man (ONE) which is not super pretty but often works with the writing to actively portray parts of the story.
The biggest problem I have with this is the consistency of various aspects of it.
very vague spoiler:
The magic, as well as numerous characters in this, are very inconsistent; it's like the first half and second half were written by two different people.
Major spoilers, don't read them unless you've nearly completed it:
Early in this book it makes you think that magic doesn't exist, that it's all smoke and mirrors, which I thought was pretty cool, but then later on it completely turns around and makes Oldman a sorcerer, which I didn't like at all. One of the best parts of this for me was trying to figure out how the Queen became young again and why she was keeping Oldman prisoner, the trick behind it that is; that's why it was super disappointing when it turned out that it actually was just magic. I also don't like that Oldman goes from using tricks to solve problems to using straight-up sorcery, if he had those powers then he easily could've used them earlier and saved himself some trouble.
I also don't like how the ending used Owen. Throughout the story he seemed like he'd grown into a decent guy who was trying to survive in a complex environment and figure out what happened to his foster brother, but in the end he's just portrayed as some stereotypical villain and for what, a little bit of youth? He's like 20-something and going to be a king; come-on, why would he do that for like 10 years, does he want to go through puberty again or something? Such a lame way to deal with a potentially interesting character.
The woman with the prosthetics and the Queen were also inconsistent but I don't feel like typing any more.
