Teachers and librarians sell books–dogs do not. I post photos of cute canines, with profound advice inspired by their posture, along with my book cover because it’s fun. But if a teacher or librarian holds my book up, reads a chapter or shelves it in a special way,that “sells” books. It sells reading, too, and reading inspires empathy and resilience. Reading also relaxes more than yoga. Google it. Or ask your librarian.
