Anyway, I read Stone of Farewell, and now I have a bit of time to write about it. If you haven't read The Dragonbone Chair, the first book in this series, go do that.
The Dragonbone Chair left Simon, Binabik, Jiriki, and Sludig on a freezing mountain, and the suriviors of Naglimund wandering the woods of northern Erkynland. Miriamele had just embarked with Cadrach on a voyage to Nabban, hoping to convince Duke Leobardis to ally with Josua, not realizing that she was already too late.
When we return to Osten Ard, Williams picks up right where he left off. Binabik and Sludig are being held by the trolls under sentence of death. Simon is slowly recovering from his fight with the dragon Igjarjuk, and Jiriki's torn between speaking for his imprisoned companions and returning to his home to perform final rites for An'nai. Meanwhile, Josua's tiny kingdom of survivors flees Norns and Bukken and tries to recover from injuries with no treatment. And over it all, King Elias and Pryrates continue to do their best to destroy world order and replace it with the Ineluki's. But when Simon collapses during Binabik's trial, he receives a strange vision from Valada Geloe, and she tells him that their only hope lies in the Stone of Farewell, or Sesuad'ra, a Sithi landmark of great power and history.
