Ragnarok is the story of the end of the world. It is a tale of the destruction of life on this planet and the end of the gods themselves. As the bombs rain down in the Battle of Britain, one young girl is evacuated to the countryside. She is struggling to make sense of her new wartime life. Then she is given a copy of Asgard and the Gods - a book of ancient Norse myths - and her inner and outer worlds are transformed. How could this child know that fifty years on many of the birds and flowers she took for granted on her walks to school would become extinct?
