I just finished this fascinating book called Room by Emma Donoghue.
The story is told by Jack, a very bright five yr. old who knows nothing of Outside. There is Ma who has tried to shield Jack from all the ugliness in their lives. She's done so well that Jack is happily unaware of their predicament. The third main character is Room an 11 sq. ft. space that is all at once small and confining and big and wonderous. To Jack it is the world but to Ma it is a prison. Others come and go from their world but always, even in freedom, there is Room.
