The book is introduced by the character/narrator Death, which underlines that mortality is very present in the lives of each character. Throughout the novel, the deaths of prominent characters reaffirm the presence of mortality. Because the novel takes place during the Second World War, death and genocide are nearly omnipresent in the novel.
Death is presented in a manner that is less distant and threatening. Because Death narrates and explains the reasons behind each character's destruction and explains how he feels that he must take the life of each character, Death is given a sense of care rather than fear. At one point, Death states "even death has a heart," which reaffirms that there is a care present in the concept of death and dying.
Language, reading and writing
Throughout the novel, language, reading, and writing are presented as symbolic elements of expression and freedom. They provide identity and personal liberation to those characters who have, or who gain, the power of literacy: "the true power of words". And they provide a framework for Liesel's coming of age. At the beginning of the story shortly after her brother's funeral, Liesel finds a book in the snow, one she is unable to read. Under tutelage by her foster father Hans, she slowly learns to read and write. By the end of the novel, her character arc is largely defined by her progress in reading and writing. The development of Liesel's literacy mirrors her physical growth and maturing over the course of the story.
Literacy skills and vernacular speech also serve as social markers. Wealthy citizens in the story are often portrayed as literate, as owning books and even their own libraries, while the poor are illiterate and do not own books. Rosa Huberman's abrasive and oft-times scatological speech towards her family and others is emblematic of the despairing lives of the poorer classes.
The Nazi burning of books in the story represents evil incarnate. Symbolically, Liesel's repeated rescues of books from Nazi bonfires represent her reclaiming of freedom and her resistance to being controlled by the all-pervasive state.
In the midst of war and loss, love is a central theme which acts as a catalyst for change and sacrifice throughout the book. Liesel overcomes her traumas by learning to love and be loved by her foster family and her friends. At the beginning of the novel, Liesel is traumatized not only by the death of her brother and her separation from her only family but also by the larger issues of war-torn Germany and the destruction wrought by the Nazi party. As Liesel's foster father Hans develops a relationship with her, this relationship helps create healing and growth. This pattern is reflected in the relational dynamic between the Hubermann family and Max. In a society ruled by governmental policies that presume to stand in judgment of who is truly human, the Hubermanns' relationship with Max defies the Nazi regime. Further, the love that Max and Liesel develop through their friendship creates a strong contrast to the fascist hate in the backdrop of the story.
The theme of love also intertwines with the themes of identity and language/reading because all of these themes have the purpose of providing freedom and power in the midst of chaos and control. Liesel's final words in her own written story are "I have hated the words and I have loved them, and I hope I have made them right." She has the power to show her love on paper.
