Answer:
Nethergave falls under the genre of scifi because the protagonist Jeremy jumped into a virtual world to escape the horrible first day of school and ended up being trapped there. Although the book is not in the future , that doesn't mean that the book is a work of science fiction. The fact that his avatar is a jaguar and has all the qualities that he aspires to have proves that the book is fictional because a human can't be a jaguar. And the fact that he's in a virtual world proves that there is some element of science and technology.
In conclusion, Gloria Skurzynski’s “Nethergrave" is nothing short of a wonderful sci-fi narrative.

Hovering on the second icon will say center align, and clicking on it will center your text.
