From out of the darkness ''an echo/ came threading its way/ through the trees.'' "Late one winter night a little girl and her father go owling. The trees stand still as statues and the world is silent as a dream. Whoo-whoo-whoo, the father calls to the mysterious nighttime bird.But there is no answer.Wordlessly the two companions walk along, for when you go owling you don't need words. You don't need anything but hope. Sometimes there isn't an owl, but sometimes there is.Distinguished author Jane Yolen has created a gentle, poetic story that lovingly depicts the special companionship of a young child and her father as well as humankind's close relatiohship to the natural world."
