Florence Williams is the author of a must-read book, The Nature Fix. Why must-read? Because contact with nature, it turns out, is one of the foundational elements of human health and well-being. Florence is not only a great science journalist, she's a fantastic storyteller, and all-around hilarious writer. In case you think of science books as medicine, this one is coated in enough sugar to make you feel like you're reading a guilty pleasure.
