And look for the forthcoming starred review of I Begin with Spring: The Life and Seasons of Henry David Thoreau (Tilbury) by Julie Dunlap, illustrated by Megan Elizabeth Baratta, in the May/June 2022 Horn Book Magazine Special Issue: The Newbery Centennial. As our reviewer noted, author Dunlap "discusses the importance of her subject’s work in a modern-day study of climate change, encouraging readers to become citizen scientists and record what they see, too." We all must "Invest in Our Planet" because "a green future is a prosperous future." What will you do to help? How will you be honoring the occasion? Share your plans with us in the comments below!
