The Nether Scroll

The Nether Scroll by Lynn Abbey is the final book of the Lost Empires series.

"Ansoain has been murdered, and her son Galimer taken hostage.

Druhallen, a young magic user, must avenge the murder of his teacher and rescue her son from a dubious fate. But not everyone is telling Druhallen the truth.

Druhallen and his companions must brave the ruins of Dekanter to find a missing artifact. . . the Nether Scroll.

Without the Nether Scroll Galimer may die. With it Druhallen may go mad."
