'Will touch all hearts - both young and old' Virginia McKenna, Born Free Foundation
When Bertie rescues an orphaned white lion cub from the African veld, the pair are inseparable - until Bertie is sent to boarding school far away in England and the lion is sold to a circus.
Bertie swears that one day they will see one another again, but it is the butterfly lion which ensures that their friendship will never be forgotten.
