The PG 17 rating is deserved. There's quite a bit of gore and creepy imagery.
The story starts out jumbled, and tangled up in mixed phrases, but the writing has slowly improved with each chapter. Although some of the vocabulary is still muddled, and either the meaning of some words is not understood, or they are simply used where some other word was intended.
Despite all of this criticism, I do think the story has been working toward a coherent goal and some of the background idea are interesting.
Luck in your adventures.
