The reaction of site.com to manga can vary greatly. It could be highly supportive, promoting and featuring manga prominently. Or it could have a more limited engagement, only showcasing selected titles. It all depends on their business strategy and target audience.
One popular title is 'The Time Machine' by H.G. Wells. It's a classic that explores time travel in a really interesting way. Another is 'Frankenstein' which can be considered a precursor to science fiction. It deals with themes like creation and the consequences of playing God.
You can try websites like Project Gutenberg. It offers a large collection of free e - books, including many science fiction works. Some of them are classic science fiction novels that are in the public domain.
I wouldn't recommend looking for unblocked manga sites as they often violate copyright laws and can be risky. It's better to use legal and authorized platforms to enjoy manga.
