i think ive read it at least twelve times... once a year since i was seven
my favorite part the first time was the land of the duffers although now it might be when they meet Ramandu and the birds all fly on to the island in "the beginning of the end of the world"
and of course my favorite line is still the very first one.. "there was a boy called eustace clarence scrubb, and he almost deserved it"
I think I have read it all the way through 4 times. However, I frequently re-read parts of it, since each chapter is like a mini-story in and of itself, and this is tied for my farourite book with the Last Battle.
My favourite part of the book is at the very end where the children are just about to reach the very end of the world, and they meet Aslan in the form of a lamb, and then later tells the children that they must learn to know Him in their world by another name (Christ). He also says here that the door to Aslan's country is from their own world and they have to pass over a river, but not to worry, for Aslan is the great Bridge Builder. I love that part .
I've reading it for the second time right now, I read the whole series for the first time (except I think I read LWW at school a looong time ago) the first week of January and I can't get enough of the stories. But anyways, I loved the parts with the Dufflepuds, they made me laugh, and basically any part with Reepicheep.
