Review Detail of UNK in My Time System

I haven't finished reading the whole thing, but I came running to leave my review, I don't want to give spoilers so I will speak superficially. Reading this book was like diving in a deep ocean, the more you sink the more you realize that you haven't reached the end, the waves carry you and take control of your body, if you still don't understand I will tell you clearly, when you start you won't want to stop because it is so amazing.
