The thrilling final instalment in Ian Green's Sunday Times Top 15 bestselling fantasy adventure series.

Hunt the mage. Save the child. Defy the storm.

Across the ruins of Ferron, the rotstorm ever rages. From its nightmarish depths, demons and goblins and rust-folk have struck forth and claimed the Northern Marches as their sanctuary. Through the Undal Protectorate, the land is gripped in a Claw Winter, a frozen mirror of the punishment laid down to the west.

Abandoned on the island of Riven, Floré and her comrades must find their way back to the Protectorate. Her daughter Marta is hidden somewhere in the north, dying from the skein-magic she cannot yet control.

After centuries of bondage, the immortal mage Tullen One-Eye has been unchained and the great god-wolf hunts again. And deep in Orubor's Wood, the god-bear Anshuka stirs from her slumber. The last time the Judges warred, an empire fell.

If she is to save her daughter and free her people, Floré will have to defeat the great wolf and kill the man they call Deathless. But how can she kill the unkillable man? And is steel alone enough to take down the gods themselves?
