Heather Whirl is fascinated by the weather and concerned about the climate. In this second adventure, Heather's magical umbrella, given to her by her eccentric great-grandmother, lands her and her friends near a raging wildfire! Heather and her friend Edward and animal companions-Fog the dog and a lizard named Blizzard-observe and learn how such fires come about. They also lend a helping hand in building a fire break, and document their adventures. Heather's journal entries, notes from her helpers, definitions, and activities provide additional information for children wanting to learn more about the weather and climate.
