This isn't the worst piece of fiction out there  especially for a free book. However, it reads like a first draft. The world is flat and lacks any development. So do the plot  characters, magic system (?), and basically every other idea in the book. It's got some interesting ideas, but that's all they are: ideas. 

Also, this entire plot takes place over 2 days. I found myself imaging that things were going on for weeks only to be reminded that years worht of "character development" happened I the past 4 hours. 

I see that the reviews for the rest of the series are a lot better, so Iight be interested in continuing the series at some point in the future to see where it goes and how the author evolves as a writer.
