There are many themes running throughout the novel and one of them is that of searching, literally, spiritually and mentally. There is a searching for an account book, a searching for God and a searching for memory. It almost seems the harder one searches, the more elusive whatever one is searching for becomes. Sometimes one has to relax and let go, in order to let the memories flow.
Both main characters, Drew and Olivia feel that God is distant. Drew even cries out “God where are you?” God in His silence seems to have abandoned them, but silence does not mean absence.
