What is an example of a metaphor in the book Tangerine by Edward Bloor?

Tangerine is a metaphor for Paul's life. What had been
good and thriving was bulldozed by greedy developers and built upon by crooked
politicians. Paul's life was a normal one until he turned five. Then, some mysterious
incident robbed him of normal sight. The termite ridden ground resulting from the houses
being built on top of rotting tangerine trees was like the family atmosphere in the
Fisher household. Something was wrong and really rotten in the family, but there was no
acknowledgement of its existence. The muck fires smoldering underground was the fear and
anger Paul felt toward his older brother Erik. The sinkhole was his collapsing soccer
career at Lake Windsor Middle when he was removed from the team for his visual
impairment.
