Arcady (Hawken Family Book 1)

From Library Journal:
In Williams's latest, the undulating Borders separate Presence from Absence. But Absence is released when Citizen Arouet ?the ruler of the realm?begins to mine bordermetal. With the Absence churning across the landscape, destroying everything in its path, Priest Solomon Hawken fights to save his family and their homestead, Arcady. This is a multilayered work combining ecological fantasy with concerns about both family relations and the stranglehold of military government. Recommended for fantasy collections.
