Vengeance of the iron dwarf - R. A Salvatore

Bloody war rages across the Forgotten Realms world in the third book of the Companions Codex, the latest series in R.A. Salvatore's New York Times best-selling saga of dark elf Drizzt Do'Urden. In the evolving world of the Forgotten Realms setting, the Sundering has given way to months of cloud-cloaked darkness, and war rages under that oppressive sky. The orcs have broken a hard-fought treaty that's held, however tentatively, for a hundred years, and the time to settle old scores has devolved into an all-out brawl for control of the ancient realms of the North.
