I really like the Goosebumps series. I have heard about the Sweet Valley as well. I wonder who wrote the "Sweet Valley" series.
I prefer genres that include: fantasy, mystery and romance. I have a majority of the fantasy genre though (usually ones with witches, wizards and vampires) so I definitely prefer that more over the rest. I was never one who enjoyed reading horror or suspense books and definitely nothing to do with the sciences.
I have always been a sucker for romance. Be it fantasy, dystopian, suspense, or a comedy, I need the book to have a romantic setup, otherwise I always feel there's something missing!!!
I mostly read either fiction (largely sci-fi, but I'm not opposed to other genres as well, as long as it's not romance), or when I read non-fiction, it's either about music movement/genre or (auto)biography of musicians.
Fiction, technological fiction, cyberpunk or something like that. Also, time travel is a huge plus for me, if someone wants to recommend me a good book and they say that it has time travel in some way, i am in for it.
I have heard James Patterson is a very good writer. I can't remember the name of the series, which is so popular. I believe it's a fantasy series or something.
