Connections

i think there are many connections between my book and other titles. The theme of the book Possession is " help can come from the most unexpected places". In the book, the main character receives a little help from her old rival. I've seen TV shows or movies on which the main characters' enemies become their friends or where they receive help from people(or things) they would never expect to get help from.(Also connecting to the book), about a year ago, my cousin used to fight with someone so much(they couldnt stand each other) and now there are really close friends(weird huh?)
