The Cerulean Storm — Troy Denning

The Thirst for Immortality....
Rajaat: The First Sorcerer, betrayed by his champions at the moment of his paramount victory, imprisoned beyond space and time.

Only Rajaat can return Athas to its verdant splendor.

When Tithian of Tyr leads his former slaves to free the ancient sorcerer, does he want to restore the world -- or claim it as his own? Before discovering the truth, Rikus, Sadira, and Neeva must conquer their own forgotten passions, a trial more perilous than battling the Dragon and all his enchanted fleets.
