Heather Whirl is fascinated by the weather! With eyes that change color in response to rain or wind or heat, Heather would like nothing more than to be a meteorologist or a climate scientist when she grows up. When Heather turns eight, her eccentric great-grandmother gives her a family heirloom--an umbrella with the power to teleport her to areas experiencing wild weather conditions. Heather's umbrella has a built-in magical doppler that alerts her to wild weather happening somewhere. In the blink of an eye, Heather travels to the middle of a superstorm! Heather observes and learns about the weather, but also lends a helping hand and documents her adventures with her friend Edward and animal companions Fog the dog and a lizard named Blizzard. Her journal entries, notes from her helpers, definitions, and activities provide additional information for the curious reader.
