Whats the theme in pages 130-170 in the marrow theives?

Different copies have different page numbers. Can you quote a line from pg 130 and I can find where you are?

Ok, the chapters are The way it all changed chapter 15 The long stumble chapter 16 Rogarou comes hunting chapter 17 On the road chapter 18 and Found chapter 19. Those are all the chapters from the Marrow theives I have to look at and answer the question what is the theme in the story from all those chapters.
