Reborn to Change my World

Maya came back from the real world to her world which was a book world. And she wasn't a character written in the story.
She was a nobody, even worse than cannon fodder. But that didn't mean she had to die with her tribe.
She was from the tribe of peaceful and nature-loving Plant vampires, who drained plants' essence instead of human blood.
But her whole tribe was killed by the Blood Vampires and she did not know why?
So she went undercover to the school where all the tribes studied because all the people who were responsible for her death were still teenagers now.
High school could be pretty fun!
To top it all, she got a gold finger. She could get any ability for a week. Cool, right?
But what was destiny planning for her?
In the distant past, it was prophesied that the unwillingness will transform to a human bearing a long curse that will be broken when she falls in love. Maya not knowing that this curse will take her life, doesn't know who is waiting and looking out for her.
A law protector god living for eternity waits for her to incarnate. He did everything to keep her curse at bay. But fate doesn't change easily.
What is her reality? Is the world she knew an illusion or a greater conspiracy?
Why was the unwillingness born? Why was the protector who was supposed to erase existence of the unwillingness protect its human form? While are they?
