The book I loved as a child was The Lion, The Witch and The Wardrobe, it really fired my imagination and I couldn't wait for the next chapter. It was the first book that I got engrossed in and lead to a lifetime love of books and reading.
To this day I still love a physical book to hold, I always use a bookmark and I make sure that no matter how well-read a book of mine is, it still looks pristine, no creases or evidence that it has been read.
I have a real respect of the written word and it all started with The Lion, The Witch and The Wardrobe!
