Astrid Spark has an incredible gift—her fingers can fix anything that is broken. More important, her magnetic fingers might just be able to fix the hole in the ozone layer. The tale unfolds with great inventiveness, comedy, and lively illustrations, as Astrid’s friends not only learn about the environment and the fragile ozone, but also build a special vehicle to catapult her into the stratosphere, a bagggoon. Yet will Astrid’s fingers be able to fix something as large as the ozone?
