This is the third book in The Artefacts of Power tetralogy (after Aurian and Harp of Winds, and before Dhiammara).
Reunited at last, the Mages Aurian and Anvar are ready to set off again in search of the last Artefact of Power, the legendary Sword of Flame. Together with their new friends, they travel to the Xandim fastness, where the shortsighted Windeye Chiamh can help them locate the lost artefact. There they'll have to face the demented former Healer-Mage Meiriel who has but one obsession, to kill Aurian's son. Meanwhile, rebellion is slowly fermenting among the Xandim people.
At the same time in Nexis, young Zanna is trying to rescue her father from the clutches of the fiendish Archmage, while as always, the cupid Eliseth is coming up with more devious ploys to thwart Miathian and seize the power of the Cauldron of Rebirth.
The Sword of Flame is what you could call a typical middle volume, in which many events take place but where the overall story in itself isn't really getting much further. Mark you, I found it quite enjoyable, but as a whole, I was less impressed, less taken aback than I had been by the richness of Harp of Wind. I guess I read it faster because I was in a hurry to jump to Dhiammara, the final volume. Consider this one a bonus.
