What's your favourite book of all time?

Most favourite book of all time is hard to pick. I was crazy about Beatrix Potter's Peter Rabbit and Enid Blyton's Amelia Jane when I was younger. Classics such as The Secret Garden, Treasure Island and Robinson Crusoe still fill me with a sense of adventure. The Little Prince is an all-time favourite. The Dark is Rising is an amazing series that I continue to re-read every christmas till this day. The book that I loved reading to my daughter: The Little Engine That Could, Harold and the Purple Crayon, all of Shel Silverstein's books.
