Temple of the winds by Terry Goodkind 2003 Sword of truth
Book Four of The Sword of Truth returns listeners to the world of Richard Cypher, a simple woods guide who never dreamed he would be named the Seeker of Truth and become caught up in magic, war, and dangers so extraordinary that the fate of his entire world would hang on his actions and decisions.
The dangerous, fanatical Imperial Order, under the leadership of the power-mad Emperor Jagang and his multitude of demonic underlings, unleashes a deadly plague. To find a cure Richard Cypher and his beloved Kahlan Amnell must seek out the legendary Temple of the Winds, a fortress of evil sealed away for three thousand years. But the path of the Seeker of Truth is never an easy one—even if he can reach the Temple at all, there is no guarantee he'll ever return.
