From the two-time Newbery Medal-winning author of Number the Stars and The Giver comes a novel about how even the smallest of dreams can break through the darkest of nights. Where do dreams come from? What stealthy nighttime messengers are the guardians of our most deeply hidden hopes and our half-forgotten fears? This imaginative novel from New York Times bestselling author Lois Lowry confronts these questions and explores the conflicts between the gentle bits and pieces of the past that come to life in dream, and the darker horrors that find their form in nightmare. In a haunting story that tiptoes between reality and fantasy, two people--a lonely, sensitive woman and a damaged, angry boy--face their own histories and discover what they can be to one another, renewed by the strength that comes from a tiny, caring creature they will never see.
