A nicely shaped, realistic story about the loss of a beloved toy--Sammy, a rabbit. The boy and his mom have bid a tearful goodbye to grandparents in Florida. Then, thinking Sammy is in his backpack, the boy leaves Sammy on the plane; despite Lost and Found's best efforts, he never shows up. Comforted by his understanding parents, Sammy grieves: eventually, though he doesn't forget Sammy, whose picture he treasures, he accepts a new toy rabbit. Roger is more rambunctious than Sammy and smells different, but he's a good friend nonetheless. The boy narrates with straightforward ease; Owens' colorful, realistic illustrations convey well the family's affection and the pathos of Sammy's loss. A reassuring story that provides a good model for dealing with trouble, large or small.
