Got to say mine was The Lion, the Witch, and The Wardrobe. I loved Narnia and would always be checking the back of my wardrobe just to make sure!! I read this to my daughter when she was five and she loved it so much it was magical to enjoy it all over again and experience that thrill of wonder! Although re-reading 6 times straight was a little much lol
I've never actually read The Lion, the Witch and the Wardrobe. I remember watching an animated film of it on television when I was probably about 8 or 9, and was so upset when a certain unfortunate event happened, I ran out to the kitchen crying. I must have felt traumatised by it as I refused to read the book later on!
