The child with the pyjamas of parting

My favorite book is the child with the pyjamas of parting.

There was a family that moved to a other house out of the city becouse of the work of the father, near the house there was an concentration camp.

Bruno like to explore and he decided to find something in the fence of the concentration camp.

When he found the fence there was a boy called Shmuel and he makes friends.One day the father of Shmuel dissapear and Bruno decided to help Shmuel to found his father instead of found his father Bruno and Shmuel enter in a gas chamber.
