Heart of black ice: Sister of darkness - Terry Goodkind (The Nicci Chronicles #4)

As Richard Rahl's emissaries to the Old World, sorceress Nicci and her companions have travelled far into unchartered territories, battling tyrants, monsters and strange magics. Now, in the wake of a brutal war unleashed around the once-shrouded city of Ildakar, they must face a terrible new threat posed by an old foe.

The Norukai, barbarian raiders and slavers, have been gathering an immense fleet among the inhospitably rocky islands that make up their home. With numbers greater than anyone could have imagined, the Norukai are poised to launch their final and most deadly war.

As foretold by the witch-woman Red, the fate of the world rests on Nicci's shoulders in the dramatic conclusion to Terry Goodkind's New York Times bestelling Nicci Chronicles.
