Review Detail of Triparadox in Gate: War of Two Worlds Part 1

This is my review after reading over 40 chapters in the first book. The story has a great world background with vivid clear explanation over what is happening on the other world as well as on earth. The author touches reasons for countries to participate in alliance against defending the gate from further invasion instead of shrugging it off. The writing and clarity seems to be top notch during the first several chapters. However, starting from chapter 30 and later, there has been a noticeable down quality in grammars as well as sentence structures. While it does not happen often, there is relatively about 30% chance that a reader may be totally confused on what a paragraph is about.
