Theories of Relativity - Third Fifth

The book is still very interesting but it is starting to be dragged out. The story dosent really have a path still and its just him trying to live on the street like the last fifth. Although he did meet his mom and found out that she is doing very well with her new husband and they dont need him anymore, it had very little significance. All he got was a letter from his Grandfather from years ago. I guess the story is going to include his grandfather very soon.
