even though the idea is new, it has been used several times, whether in the movie industry, whether in gaming, or in other books, so it has a lot of competition. but it still manages to be interesting, and I hope I'm not biased when saying that it can be life-changing if you are starting to know this concept. nearly flawless character development, for such a short book, it's almost as strong as impactful "Avatar the Last Airbender". the story has a smooth and pleasing flow while still managing to stay real. very underrated.
