From Publishers Weekly

While juggling a complex epic fantasy plot may be child's play for veteran word-wizard Williams (_Otherland_), the bewildered star players of the fine second volume in his Shadowmarch trilogy must deal with a very adult world being transformed by war, magic, secrets and a weird, powerful scrying-mirror. Back in Southmarch, Hendon Tolly has usurped the throne, while King Olin's held in captivity in Hierosol. Olin's young twins, Princess Briony and Prince Barrick Eddon, struggle to survive in exile on separate but equally perilous paths. Barrick's trapped behind the Shadowline with Capt. Ferras Vansen; Gyir the Storm Lantern, a formidable, faceless fairy; and Skurn, a quirky talking raven. Briony's helped by a forest demigoddess and winds up with a band of endangered traveling thespians. Though the pace lags at times, bestseller Williams once again delivers a sweeping spellbinder full of mystical wonder. Author tour. (Mar.)
