A mosaic of memories and observations forms the fragmented portrait of Aunt Magda's life in Tel Aviv. Born in Vienna, Magda is a widow who retains her German language after years in Israel. The novel explores her life through two hundred and thirty-three distinct pieces, offering glimpses into her childhood, marriage, relationships with her nephew and best friend Frau Stier, her appreciation for Wildegans' poetry, and her culinary preferences like apple strudel. The narrative also touches upon her visions, dreams, minor incidents like stolen handbags, and a developing relationship with a gentleman admirer, all set against the backdrop of her favorite cafe.

The Christ of Fish is recognized for its unique narrative structure, piecing together a character's life through a multitude of small fragments. Critics have noted Hoffmann's skill in creating a vivid portrait of Aunt Magda, a woman navigating her identity across different cultures and languages. The novel's approach, which eschews a linear plot for a mosaic of moments, allows for a deep dive into the protagonist's inner world and the nuances of her experiences. This method invites readers to actively assemble their understanding of Magda, highlighting the subjective nature of memory and perception.
