Half Way Through The Lovely Bones

I am half way done with the Lovely Bones and it is getting more and more intense. So much has been revealed about the murder and the family problems going on while Susie is "inbetween" Earth and Heaven. Lindsay, Susie's sister is siding with their father, that Mr. Harvey committed the murder but Len the officer refuses to do anything with out legitimate evidence. Susie's mom is also acting differently, but she does something terrible: she cheats on her husband with Len. I think its terrible what she did, but I somewhat understand because she probably feels so much tension and sadness with her husband that she needs to take her mind off of the tragedy that had occurred. I feel so bad for the Dad because he feels so alone, and is the only one who feels that it was Mr. Harvey who murdered Susie. Lindsay also has a feeling he is the murderer but doesn't tell him until later on. Meanwhile, we find out about Ray-Susie's friend who liked her and made her well aware of that, before she was killed. Ray was a suspect in the murder of Susie but he was proven not guilty. It is really sad what happened to Susie, and hopefully her dad will be able to find the murderer of his daughter.
