"Bad truck, bad guy; bad wave, bad bye . . ." A boy and his family are packing up their old home, and the morning feels scary and sad. But when he arrives at his new home, an evening of good byes awaits: bye to new friends, bye to glowing fireflies, bye to climbing trees. The New York Times bestselling author Deborah Underwood's spare text and the Boston Globe-Horn Book Award winner Jonathan Bean's lush, layered illustrations perfectly capture the complex emotions of moving day. The child-centric transition from dreary morning to cheerful evening comforts young readers facing big changes of their own.
