A card comes from Sage Creek, a Montana ranch town that runs on sun and wind: its battery keeps running flat on winter nights, and nobody knows why. Ava measures it at noon and finds the answer at once. It is the wrong answer. Then an ice storm brings the power line down, and the stillest, coldest night of the winter is coming.

About the Green Guardians series
Green Guardians is a series of illustrated adventures for readers aged ten to twelve about conservation and looking after the living world. Ava, who organises everything, and Mateo, who can read a track in the mud, belong to a quiet network of young rangers run by Ranger June, and answer real requests for help from scientists and communities. Each book delivers one conservation topic through a real place and a real problem, and shows how things are connected.
