The mayor's wife in The Book Thief, Ilsa Hermann, appears to be motivated by several factors in her generosity towards Liesel. Firstly, she seems to recognize Liesel's love of books and reading, and may see a kindred spirit in the young girl. Secondly, Ilsa may be motivated by a sense of guilt or remorse over her husband's role in the Nazi regime, and may see helping Liesel as a way to make amends for her complicity. Finally, Ilsa may simply feel a sense of compassion for Liesel, who has suffered greatly in her young life.
The fact that books and reading are at the center of another one of Liesel's important relationships is significant for several reasons. Firstly, it underscores the importance of literature and storytelling in the novel, and how they can provide solace and comfort in times of hardship. Secondly, it highlights the power of human connection, even in the face of great adversity. Finally, it suggests that reading and books can be a means of transcending societal divisions and prejudices, as Liesel's relationship with Ilsa Hermann shows.
