Audrey is an example of symbolism in this novel. She is symbollic of change, new growth and possibility for Kieran and his family. She represents changes he has made in his life since the storm and Finn's death, and she represents the positive future that lies ahead, not only for Kiernan, but for Mia and Audrey and Kiernan's parents, as well. Initially, Audrey is laying "milk-drunk" against Kiernan's chest. At three months old she "is growing heavy now." Both quotes, from the first pages of the novel, are dark and may represent Kiernan's outlook, as the novel begins, as much or more than they describe Audrey. On the last page of the novel, Kieran speaks positively to Mia, as he reaches out for her and Audrey, puts his arm around them both, "Let's go. Let's go up." So the reader sees the change that this new life has brought and how it symbolizes the positive future that lies ahead for all as "they make their way together, up to higher ground."
