Once in Blueberry Dell is a picture book written by Dawn L. Watkins and illustrated by Tim Davis. The High Prince is coming, and everyone in Blueberry Dell is excited. The moles are busy preparing the very best for their Prince, so they have no time for a tired miller who asks for shelter. Happy Mole is the only one who takes time to help. And the very next day, his kindness is rewarded. Once in Blueberry Dell illustrates the importance of kindness to everyone, not just those who are powerful.
