The Shuttle That Weaves the Shroud - The Foreign Sorcerer, #2

He thought he had seen everything, then the people of the Cities called him a hero. Velananc has vanished, a new Fate roams the streets, and Japhet has other problems: the local cabal has admitted they know he's present.

Worse, the Fah Disan has come to him with a terrible suspicion: this is the doing of his brethren.

He left Liath-Tamren to remove himself from Japhet's affairs before his meddling got him killed, but he finds himself more invested than ever. The secrets he uncovers will have far-reaching implications.
