'His Dark Materials' trilogy by Phillip Pullman is a great story. I like the way it's constantly changing in plot and how the characters think and react to the situations around them, but the third book goes a bit overboard with all the ideas in it. It's still a great trilogy though.
My favourite trilogy's got to be 'The Lord Of The Rings'. Almost everyone's got to at least heard of it, even if they haven't been fortunate enough to read it. I recommend reading 'The Hobbit' before you read LOTR.
Yah I agree with all of that.
I want that Subtle Knife! >.<
