More battles against the Nameless One: the third entry in Feist’s latest fantasy series set in Midkemia (Krondor the Assassins, 1999, etc.) and similarly based on a computer game. Once again, a large cast of white hats—Prince Arutha of Krondor, Squire James, Lieutenant William, Jazhara the magician, etc.—clash with a bunch of black hats, including the mysterious Sidi, holder of an evil amulet, the huge pirate Bear, and the criminal Crawler. This episode’s McGuffin is the holy and miraculous gemstone of the title. There’s even an ending, sort of, though the overall struggle continues: perfect for series fans.
