"Hamilton's repetitive story is simple but effective in conveying the evolution of wolves into dogs. Kids will love noticing the difference in the humans' lives as the years pass.Kim's watercolor, acrylic, and gouache artwork adds warmth and familiarity to the story with its friendly faces, guarded-then-playful pups, and use of vivid colors.A great story time choice for all libraries, perfect for launching discussions of fact and speculation, and how they can be combined." -- School Library Journal , starred review "A lyrical exploration of how wolves evolved into dogs.Delightful--especially appealing for young readers who have or wish for a puppy.
