Book excerpt: If you've never known what a wildebeest is, you'll find out now in this latest Where? Is title about the Serengeti. Each year, over 1.5 million wildebeest make a harrowing journey (more than one thousand miles!) between Tanzania and Kenya. They are in search of new land to graze. Even if these creatures avoid vicious attacks from lions and crocodiles, they could still fall prey to thirst, hunger, and exhaustion. This book not only follows the exciting Migration, but also tells about the other creatures and peoples that co-exist along these beautiful landscapes of the Serengeti.
