The Neverending Story is the tale of Fantasica the magical land of all the stories ever written and ever to be written. Bastian Balthazar Bux is one of those lucky few who can reach Fantasica and give the childlike emperor a new name but how. He isn't a likely hero he is fat, week and timid so with the help of Atreyu he has to save them all from the Nothing.
My favorite character was Atreyu because he was brave, not just in fighting wild beasts but in doing what is right for his friends and protecting them even if they don't like it. Atreyu had to go through many hardships and points where he felt he couldn't go on but for the sake of all in Fantasica he risked it all.
The Never-ending Story is a great read and it also has a good film to go with it. The film sticks to the book very accurately but if you do not like the film do not be put off. My suggestion is read the book first and then watch the film because they are both excellent.
