The time of peace is over. The time of war has begun.

Bera is struggling to reconcile her desire to be an ordinary woman with the weight of her Valla duty to shape the future. Love and friendship vie with her longing for freedom at sea on her beloved longboat. Warned that Chaos is coming and that Vikings have taken her kin as slaves, Bera realises her destiny is to follow them to Wolf Island, a land that has abandoned the old gods.

In a quest to save her loved ones, Bera must use her smith's iron lore and the knowledge of her Valla ancestors to follow an ancient path into a dark labyrinth, where human time is meaningless. There, she confronts her worst foe to finally bring peace – at the cost of a life.

The voyage that began with Sea Paths and continued with Obsidian ends with Landfall, Bera's most dangerous and important journey of all.
