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 what it means before so many lives are lost again.

Ice, myth, magic and danger in this bone-chilling, page-turning, beautifully written fantasy novel set in the same world as A SHIVER OF SNOW AND SKY. Blood-red lights have appeared in the sky over the frozen island of Skane, causing a cloak of fear and suspicion to fall over the village like a blanket of snow. In a desperate attempt to keep out the plague, the village elders barricade its borders - no-one, no matter how in need of help, will be permitted to enter in case they bring infection with them. Teenager Janna refuses to turn her back on people seeking refuge and is banished to the swirling snow and lurking darkness beyond the village. Can she survive? Samantha Shannon, internationally bestselling author of The Bone Season, says: 'It reads like a long-lost fable, rich with beauty and imagination. A world you won't forget.'
