The theme of the said short story 'Nethergrave' by Gloria Skurzynski is a Science Fiction. The story is all about the impact of science and technology on the world. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarification about the said question

The theme of Nethergrave as I see it is that you shouldn't trust everyone. For example, Jeremy entered the virtual world without any other reason besides loneliness, and so as a result he trusted his whole being to the internet. And this was, in my opinion, a huge mistake, the internet is shady, you can't truly trust anyone on the internet. Yet Jeremy jumped right into it, without a second thought. I find this, in my opinion, foolish.
