Not a bad story overall, but the writing style, characters, and dialogue all create a pretty immature, young adult feel. Maybe that was the demographic the author is aiming at, I don’t know. I just wanted to put it out there as a bit of forewarning.
For what it is, the book is well written and entertaining, and the audio team is excellent. If you like superheroes and LitRPG, you could do much worse.
