Jeffers (Brother Eagle, Sister Sky ) raises the curtain on an energetic and child-friendly distillation of the Nutcracker ballet (as opposed to the full-length E.T.A. Hoffman fairy tale). Here ballerinas in an array of tutus pirouette and waltz through the magical elements of that tale, familiar to many young dance students. Jeffers's soft watercolors, adopting a range of perspectives, capture both the drama of the classic story and the elegance of choreography, in a volume likely to leave youngsters longing to attend a live performance. Ages 3-8. (Oct.)
