I read The Chronicles of Narnia when I was in school, also used to read Hardy Boys, Agathe Christie, The Three Investigators.
I recently finished reading "The Belgariad" and "The Mallorean" both by Edward Haddings. They are a brilliantly written Fantasy novel series. I am now looking for "Belgarath, the sorcerer" and "Polgara, the sorceress"; prequels to the above books.
And some guys had also suggested the Twilight series to me but it didn't appeal to me. Reason, bad narration even if the plot's good. But you can try them if you like vampire stories.
