‘It reads like a long-lost fable, rich with beauty and imagination. A world you won’t forget.’ Samantha Shannon, international bestselling author of The Bone Season. 

Red, red, the lights glow red, 

Beware the danger up ahead…

On the frozen island of Skane, the sky speaks. Beautiful lights appear on clear nights, and their colours have meaning: Green means all is well, and the Goddess is happy. Blue means a snow storm is on the way. And then there’s red. Red is rare. A warning.

Seventeen years ago the sky turned red just as Osa was born, unleashing a plague that claimed the lives of hundreds of villagers, including her own mother. This time, when the night sky once again bleeds crimson, she must discover how to stop the onslaught before so many lives are lost again.
