It is 1920, central Russia. The Red Terror tightens its hold. Kolya has deserted his Red Army unit and returns home to bury his brother and reunite with his wife and sons. But he finds the village silent and empty. The men have been massacred in the forest. The women and children have disappeared. In this remote, rural Russian community the folk tales mothers tell their children by candlelight take on powerful significance and the terrifying legend of Koschei, The Deathless One, begins to feel very real. Kolya sets out on a journey through dense, haunting forests and across vast plains as bitter winter sets in, in the desperate hope he will find his wife and two boys, and find them alive. But there are very dark things in Kolya’s past. And, as he strives to find his family, there’s someone or something on his trail…

In the tradition of City of Thieves and Child 44, a troubled First World War veteran races across the frozen steppe of 1930s Ukraine to save a child from a shadowy killer with unthinkable plans. December 1930, Western Ukraine. Luka is a war veteran who now wants a quiet life with his family. His village has, so far, remained hidden from the advancing Soviet brutality, but everything changes the day the stranger arrives, pulling a sled bearing a terrible cargo. The villager’s fear turns deadly and they think they can save themselves, but their anger has cursed them: when calm is restored, a little girl has vanished. Luka is the only man with the skills to find who could have stolen a child in these frozen lands - and besides, the missing girl is best friend to Luka’s daughter, and he swears he will find her. Together with his sons, Luka sets out in pursuit across lands ravaged by war and gripped by treachery. Soon they realise that the man they are tracking is no ordinary criminal, but a skilful hunter with the child as the bait in his twisted game. It will take all of Luka's strength to battle the harshest of conditions, and all of his wit to stay a step ahead of Soviet authorities. And though his toughest enemy is the man he tracks, his strongest bond is a promise to his family back at home
