The book I'm currently reading is "Hold Still," by Nina LaCour. The current theme in the book seems to be connected with the five stages of grief and loss [or the Kubler-Ross model]: denial, anger, bargaining, depression, and acceptance.
In the beginning, the main character, Caitlin, is going through the stage of denial. Her best friend, Ingrid, committed suicide. Caitlin's true feelings are obvious, but she denies them, and says that she feels fine. Going deeper into the book, a friend comes over, and talks to her about Ingrid, then says, "It was harsh, though, the way you told me. I learned the stages of grief once. I think you might be in the anger stage." [page 75.]
That is the first time the stages of grief are ever named in the book. Not only is she going through a stage of anger, but she's still in the stage of denial, depression, and going a little into the stage of acceptance. She accepts the fact that Ingrid is dead, but feels angry at her, and herself. She also denies her emotions to the rest of the world, and denies it to herself to calm herself down.
Caitlin shows the stages of grief through actions, not only by words. In the book, she finds Ingrid's journal, and struggles in deciding whether to read it or not, which shows the stage of depression and denial. After reading the first two pages, she shows the stage of anger by throwing the book into her closet.
The five stages of grief can be expressed in different ways, depending on the person's character. But the stages are impossible to evade. The way a person goes through the stages reflect how great and hurtful the loss was to them.
