The dreadful news about people being kidnapped and being secluded for several years and somehow able to escape, have always got people's attention and also writer's imagination. In this novel the story is seen through the eyes of a 5 year old child, product of a series of abuse committed to a 19 year old girl whose name is never mentioned, and who we know only as Ma. I think this change of angle makes for a very interesting way of telling the story, and although sometimes one gets annoyed by the things the kid says or thinks is a refreshing look at this topic. 
 Sometime ago I read 'The collector' and in that book we get to read the story through the victim's perspective and also the kidnapper's one, but in this book we have a victim who is not fully aware of the injustice that is being done to him and his Ma. 
 I think is a great book, although some parts lacked realism.
