Returning to Earth-Week 3, Post B

Previously the story was being narrated by Donald with occasional interruptions from Cynthia. Now the story is being told by K, a nephew a Donald and Cynthia. It's interesting to read the memories K tells about Donald and Cynthia's family. I find that I learn a great deal more about them from K. This family seems now to be a little more unorthodox than I imagined. For example, we learn that K and Clare, Donald's daughter and K's cousin, were lovers when they were eighteen. This is a bit odd and I later learn that Clare broke up with K because she believed that K was only dating her to get to her mother, Cynthia (K's aunt). K admitted to wanting to be with Cynthia. This novel is about Donald's written history of his family and this new aspect to the novel is confusing me. K once mentions reading the history Donald has written, but then continues with his storytelling. I'm not sure what any of these stories really have to do with the main component of the novel. I am not far in the K portion of this novel so hopefully its purpose will make itself clear to me as I read on.
