Once by Morris Gleitzman is the story of a young Jewish boy who is determined to escape the orphanage he lives in to save his Jewish parents from the Nazis in the occupied Poland of the Second World War.

Everybody deserves to have something good in their life. At least Once.

Once I escaped from an orphanage to find Mum and Dad.

Once I saved a girl called Zelda from a burning house.

Once I made a Nazi with a toothache laugh.

My name is Felix. This is my story.

Once is the first in a series of children's novels about Felix, a Jewish orphan caught in the middle of the Holocaust, from Australian author Morris Gleitzman - author of Bumface and Boy Overboard. The next books in the series Then, Now and After are also available from Puffin.
