This book is a part of a series of three books that deal with gases in the atmosphere. The River in the Sky deals with Oxygen. When Bea, the curious 5-year-old protagonist of this series persists in asking questions, she succeeds in learning a lot. In The River in The Sky, the first of a series of three books, Bea learns all about oxygen and why organisms called diatoms are the secret to our supply of this life-giving gas. A unique feature of this series is the invitation extended to the young reader to actively identify with Bea.
