Michael Bond's Paddington Bear having travelled from Peru to a new life in Notting Hill, via Paddington station, makes Jon Walter's (Close to the Wind) List of the top 10 refugee heroes in Children's Books.
Who else makes the list? Superman from Krypton to Earth, and Doctor Who, Hazel from Watership Down, James and the Giant Peach, and Refugee Boy... there are more than ten suggested in a range of categories showing the way the refugee character can be a hero.
There's also Arthur Dent from Hitchhiker's Guide to the Galaxy, I wasn't sure if this was a Children's Book, I read it in Sixth Form, modern Year 12 .....so I guess maybe.
