What is the theme in Blood Test by Jonathan Kellerman?

Dreams are an important theme in this story, especially as it relates to the plot involving Woody and his family. Woody's very birth is caused by the fact that Mr. Swopes loses a dream that had been his life for a full decade. Mr. Swopes had planned, worked and cultivated the dream of an orchard producing a fruit called Cherimoya. He'd gone so far as to induce fruit buyers to pledge to purchase the entire crop of his first year.
