Lab Girl is a book about work and about love, and the mountains that can be moved when those two things come together. It is told through Jahren's remarkable stories: about the discoveries she has made in her lab, as well as her struggle to get there; about her childhood playing in her father's laboratory; about how lab work became a sanctuary for both her heart and her hands; about Bill, the brilliant, wounded man who became her loyal colleague and best friend; about their field trips - sometimes authorised, sometimes very much not - that took them from the Midwest across the USA, to Norway and to Ireland, from the pale skies of North Pole to tropical Hawaii; and about her constant striving to do and be her best, and her unswerving dedication to her life's work.
