Reviews

"There is danger, drama, and joy as Miller describes the birth of a new calf, encounters with predators and nomadic hunters, and the rigors of annual migration. . . . Vivid writing and equally impressive illustrations make this an excellent science title for young readers."--Kirkus Reviews-- "Kirkus Reviews"
