The Iron Wars by Paul Kearney
The Kingdom of Hebrion has been thrown into turmoil, following its release from the clutches of the Church. Its capital in ruins, its king in a coma, Isolla, Abeleyn's bride-to-be, and Jemilla, his scheming mistress, step into the power vacuum. Both are intent on taking control of Hebrion for themselves and a fierce power struggle ensues. To further complicate things, the explorer Richard Hawkwood returns to Hebrion with news of a new continent in the west and something terrible lurking in his ship's hold. This third book in the series continues the acclaimed saga of politics and religion in a world rife with magic, terror and war.
