Birth
Ultimately, it was a birth that brought investigator Aaron Falk to a town in Southern Australia. Falk's friend invites him to his town to celebrate the birth of his daughter and so that Falk can go to his daughter's christening. Ironically, birth gives way to death. Because of the aforementioned christening, Falk is introduced to the cases of the women who are missing. And without birth and the positive things associated with it, Falk wouldn't have found justice for all of the women who went missing.
Death
Although it doesn't explicitly show up at the end of the novel, death plays an important part of Exiles: A Novel. Eventually, investigator Aaron Falk discovers that some of the women who had been kidnapped were dead, murdered by their captors. Death alters the lives of everyone in the world when it affects them; it doubly affects the lives of the families and friends of the women who were kidnapped and murdered in a town in Southern Australia.
The importance of having friends
It becomes clear throughout the novel how important it is for a person to have friends. After investigator Aaron Falk agrees to investigate the disappearance of several women in a town in Southern Australia, he is quickly invited into some of their friend groups. He quickly discovers just how supportive and important those friends are to people's lives. As with every friend, there were disagreements between the women and their friends. However, the friends also proved to be instrumental in Aaron Falk figuring out who kidnapped each of the women.
