The Hidden City by David Eddings - WARNING! I cannot review this book without spoiling the others in the series. Read no further if you're planning on reading this series and don't want it spoilt for you.THE ULTIMATE BATTLE
Sparhawk, the Greatest of Pandion Knights, has offered freedom to the Troll-Gods trapped in the Blue Rose in exchange for their aid in fighting Cyrgon, the sinister god of the Cyrgai. But Cyrgon has turned to the unspeakable arts of Zemoch magic in his war against the Tamul Empire. He has brought back to the world the very essence of evil which was cast out at the beginning of time by Azash and the other Elder Gods. Klæl! As ancient as the Blue Rose, and as powerful.
The ultimate battle between Blue Rose and Klæl must be fought - though Ehlana is helf prisoner by the enemy in the Hidden City, defended by Klæl. The time for strategy and hope is past. From the blurb.
