"When someone asked [Barbara Kingsolver] what her background in science has given her, she said:
'A passion for research. The best research gets your fingers dusty and your shoes dirty, especially because a novel is made of details. I had to translate places through my senses into the senses of my readers. I had to know what a place smelled like, what it sounded like [...] There's no substitute for that. I've been steeped in evidence-based truth.'"
