Publisher's blurb: Vikings in this frozen frontier tell of the son of the Sun, the Heart of the Traitor, and the Sapphire of Countless Facets. Like such a jewel indeed, these are all different ways to see the same treasure, kept by the Giants beyond the sea in their ice castle of Vallenheim. The Lord of Ravensfjord entrusts you alone to brave the seas and the world of ice. Shall you dare to enter the ice castle where Giants rule and steal from their vaults the very treasure of the Sun itself?
