Der Text:
This book is told by two narrators, Martha and Scott. Martha is a twelve years old girl, who is very different from other kids her aged. She has no TV, no computer, no cool clothes and no friends. It`s because of the strict religious group, where her parents are members. She has got a big sister named Mary who her father sent away when Martha was six years old. She is very isolated in her home as she can`t bring friends back to her house because they might find out about Abomination, the family`s secret. At school she is bullied by the other kids.
Scott is a very ordinary boy who is really popular at school. He has just moved to the area and takes part in chasing Martha home from school everyday with the rest of the bullies. He then begins getting really friendly with Martha and then they were best friends.
The problem was that Marthas parents dürfen nicht erfahren dass sie einen Freund hat. So they had to meet themselves in secret. One day Scott knocked on Martha`s door, when her parents have to work. She was shocked because he doesn`t find out about the Abomination. She let him inside the house and he heard something crying. Martha hatte keinen anderen Ausweg als ihn rauszuschmeißen. Few days ago she decides telling him the truth, because he was the only friend she has.
