Brother Sun, Sister Moon is a glorious retelling of Saint Francis of Assisi's "Canticle of the Creatures." Rarely does a picture book meld word and illustration so seamlessly; the traditional, simple language of Katherine Paterson's "reimagining" of the prayer is translated into image through Pamela Dalton's quiet, detailed cut-paper spreads. Paterson and Dalton's collaboration is a wonderful testament to God's presence in nature, and it also provides a lovely, clear example of personification for children. A humbly wonderful achievement.
