In 2017, Robert Macfarlane and Jackie Morris collaborated on The Lost Spells, a collection of poems and illustrations about the wonders of everyday nature, from birch trees to red foxes. Now their book is coming to life as a musical. The plot? A nameless young girl finds a book of spells that sends her on a fantastical journey through the wild. Lyrics are by Mary Erskine and Will Dollard. —Jensen Davis
