Told in haiku-based American Sentences and pictures, Yugen is the story of a boy and his mother, inspired by the profound concept of "yugen," a Japanese word for the mystery and beauty of the universe and of human experience. The second collaboration between Caldecott-winning illustrator Ed Young and Mark Reibstein after their award-winning 2008 debut, Wabi Sabi, Yugen is a book of longing and remembrance that is unequaled in its beauty and poetic simplicity.
