What if you woke up one morning and had the chance to change the world – while still in your pyjamas?

This is exactly what happens to 9-year-old Clara, the empowered climate-heroine in Katarina Wallentin's second children's book about one girl's quest to restore the earth's tainted beauty and the courage she needs to muster when possibility knocks.

In this eco-adventure illustrated by Roser Cusso, that knock comes when Clara is met by a female disgruntled polar-bear who, sick of rising waters and diminishing fish reserves, floats in from the north pole in a red hot air balloon to find a human cub who will help.
