This book captured me in a way that some fiction can. I was totally absorbed in Pollan's perspective in this book, and in the four stories he presents here. The apple, the tulip, the marijuana plant, and the potato become agents in their own evolution, in Pollan's view. He proposes that these plants (and others too) manipulate humans by appealing to our various senses/appetites in order to control their own destiny.
Even if that particular twist of viewpoint doesn't appeal, the descriptions and histories of these four plants and their interactions with humans makes for a fascinating story. The story of Johnny Appleseed alone is worth reading, not to mention a whole chapter on intoxicants like marijuana.
Pollan's research is integrated seamlessly into his easy-to-read narrative.
