I don’t know how else to say this, but the entire series is the wish fulfillment of a lonely, hormonal, teenage boy.
The protagonist is a Mary Sue who’s only conflicts are overcoming childhood trauma and dealing with the consequences of their awesome power and intellect. The story’s love interest is characterized initially to be the ultimate symbol of sex and mystery. Later we learn that she is essentially a high end escort. The reader is made to sympathize with her, supposedly for the world’s lack of female job opportunities, but mainly because of the protagonist’s absolute SIMP behavior towards her. For two books, the protagonist watches his love interest assumably date, etc... other men. There’s a special part of the internet and literature for this sort of subject matter. If that’s what the author had in mind for his series, he should have marketed it that way.
All in all, the books waste far too much time dedicated to constructing the relationship between these pathetic characters. There is a complete lack of time focused on advancing the story towards the main conflict: confronting the Chandrian. Very well constructed prose however...
