What are some of the main conflicts/problems in Daniel's Story?

Daniel’s Story is a story of death and survival, of desperation and hope, evil and love. The story is told from Daniel’s point of view as he experiences the atrocities of the holocaust for Jews in central Europe. When the story opens, he is 14 years old, riding on a train and looking at pictures in his photo album. Daniel uses a photograph album to spark his memory of events from when he was six years old until the day he and his family are loaded onto the train bound for the Lodz ghetto.
