Here's why:
* Dominos symbolize chance and fate: The dominoes are arranged in a precarious way, suggesting the possibility of them falling and disrupting the order. This reflects the unpredictable nature of life, especially during wartime, and the constant threat of danger.
* The color of the dominos (black and white) represents the duality of life: Black represents darkness, death, and the horrors of war, while white represents hope, innocence, and the resilience of the human spirit.
* Dominos represent the interconnectedness of life: Each domino, when it falls, causes a chain reaction, affecting others around it. This mirrors the interconnectedness of the characters in the book, whose lives are forever intertwined by the war and their choices.
* The falling dominos could symbolize the devastation of war: The act of the dominoes falling could be interpreted as the impact of war on individuals and society, tearing apart lives and leaving nothing but destruction.
While the book doesn't explicitly mention dominos, the imagery on the cover is chosen carefully to evoke the themes and atmosphere of the story. The dominos act as a powerful symbol, inviting readers to reflect on the fragility of life and the enduring power of hope even in the face of immense adversity.
