In this dense passage, the author uses personification, a metaphor, and an idiom to convey the unsettling influence of spring on both the natural world and on Antonio’s Márez brothers. Antonio explains, warily:
The lime-green of spring came one night and touched the river trees. Dark buds appeared on branches, and it seemed that the same sleeping sap that fed them began to churn through my brothers. I sensed their restlessness, and I began to understand why the blood of spring is called the bad blood.
