Book excerpt: Today Riley's family is celebrating Jasper's Day. Everything they do will be in honor of Jasper --- sort of like a birthday. But it isn't Jasper's birthday. The old dog's cancer has gotten really bad. Riley knows they can't let him suffer any longer, but letting go will be the hardest thing he's ever had to do. Marjorie Blain Parker's tender story is filled with smiles, tears and the joy of special memories, and Janet Wilson's gentle pastels capture the depth of love shared by a boy and his dog. Together, they speak of acceptance, remembrance and the importance of cherishing life's every moment.
