The author is a botanist at the Pew Gardens in London. This is his life story of his efforts to save plants that are on the verge of extinction. He has traveled the world to find, collect, and propagate these plants. The book reads like a fiction novel, it's exciting to hear about his adventures. After finishing reading the book, I came away with a sense of disappointment at how fast the earth is changing, and a thankfulness that there are people like the author working hard to preserve our heritage.
