When DS10 was younger and was going to read a series I would read the first one to see how it was but it's too much for me now. I tell him to be kind to himself with his reading. If the story does not feel right or he thinks I will not approve then we need to find another book. DS is sensitive and loved the Guadians of Ga'Hoole. It may be your is just not ready for these now. My son is scare of Harry Potter and won't go near them or the movies. I would suggest not going to a movie of a book he is not comfortable with.
