Lab Girl

Acclaimed scientist Hope Jahren has built three laboratories in which she's studied trees, flowers, seeds, and soil. Her first book is a revelatory treatise on plant life--but it is also so much more. Lab Girl is a book about work, love, and the mountains that can be moved when those two things come together. It is told through Jahren's remarkable stories: about her childhood in rural Minnesota with an uncompromising mother and a father who encouraged hours of play in his classroom's labs; about how she found a sanctuary in science, and learned to perform lab work done "with both the heart and the hands"; and about the inevitable disappointments, but also the triumphs and exhilarating discoveries, of scientific work. Jahren's probing look at plants, her astonishing tenacity of spirit, and her acute insights on nature enliven every page of this extraordinary book. Lab Girl opens your eyes to the beautiful, sophisticated mechanisms within every leaf, blade of grass, and flower petal. Here is an eloquent demonstration of what can happen when you find the stamina, passion, and sense of sacrifice needed to make a life out of what you truly love, as you discover along the way the person you were meant to be.
