Good sci-fi/Fantasy books for intermediate english reader?

[LucasAurélio]

Hi. I'm studying English and I like to read a lot. Then I want some recommendation of sci-fi/Fantasy book for the intermediate English reader. Just to have an idea of my English level, I can read articles, like Wikipedia and blogs about different subjects, and news on the internet. I need a kind of simple English book. I don't need a book with very simple English, but a book with not too complex English! Sorry for the mistakes. If I made some mistake here please correct me, it is very important to me.

Books by R.L. Stine are good reads for intermediate English readers. He's also written a few books for the "advanced" reader.
