Is the sentence right?
A. I like reading science fictions.
B. I like reading science fiction.
Could you please if both are correct and native, actually I'm not sure if B is ok as I could google both of them on line, thank you so much.
By the way, if I want to introduce a book (written 20 years ago) to one of my friends, should I use present tense or past tense to describe the content of the book , thank you so much.
