Elantris
(Book)

The godlike inhabitants of Elantris, once the capital of the land of Arelon, have degenerated into powerless, tortured souls, unable to die, after the city's magic inexplicably broke 10 years earlier. When the same curse strikes Prince Raoden of Arelon and he's imprisoned in Elantris, he refuses to surrender to his grim fate and instead strives to create a society out of the fallen and to unlock the secret that will restore the city's glory. Meanwhile, Princess Sarene of Kae (Arelon's new capital), who was betrothed to Raoden sight unseen, believes her intended has died. Officially declared his widow, she must use her political savvy and wit to protect Kae from malevolent forces without and within the city, chiefly Hrathen, a leader of the creepy Shu-Dereth faith, who aims to either convert Kae or destroy it within three months.
