What is the main conflict in Brother Odd by Dean Koontz?

Brother Odd by Dean Koontz is based on the character Odd Thomas and his attempt to find peace in the Californian mountain monastery of St. Bartholomew's. Odd has a rather unique gift—he sees dead people—those who are unable to cross over are drawn to him in hopes that he can fix what holds them here. Some want comfort, some forgiveness and others have motives he is unable to grasp. They often complicate his life.
