Lydia Wylie-Kellermann is an author and activist I’ve admired for a long time, and I’m so happy to share her with you. Her latest book, The Sandbox Revolution, is a collection of essays from parent-activists around the U.S. It offers advice for raising children committed to social justice in the world today. Lydia offers beautiful forwards to each section of the book. When she’s not writing books, Lydia is the editor of Geez magazine, a paper-only publication that comes to your door four times a year with inspiration for living life more simply and justly.
