The sky speaks on the frozen island of Skane. Beautiful lights appear and their colours have meaning: Green means all is well, blue means a snowstorm is coming. And then there's red: Rare. A warning. When the sky last shone red, a terrible plague came to the island - this time around, can our heroine Osa prevent so many lives being lost again?
The people of Skane know that the sky speaks. Green means all is well, blue means a snow storm is on the way and red, a rare colour, is a warning sign. 17 years ago the sky turned red just as Osa was born. A plague claimed the lives of hundred of villagers including Osa's mother. Now the sky has turned red once again and Osa must discover what it means before so many lives are lost again.
