Ryel Mirai, Lord Adept of the great wysard-citadel Markul, continues his search for the lost spell capable of rejoining body and soul, thus bringing his beloved instructor, Edris, back to life. But someone seeks to thwart his quest: Lord Michael Essern, a dedicated student of the Arts of Death. Lord Michael has sworn allegiance to the daimon Dagar, who seeks to return to the World re-embodied in Ryel's form. Ryel began his quest by freeing the Sovrena Diara from Dagar's tormenting spells. In Lord Brother, Dagar draws the young wysard deeper into danger, ever closer to the fulfillment of the demon's plans to plunge the World into unending torment. When Ryel becomes involved with the shadowy cult of the Sword Brotherhood he unwittingly jeopardizes his plan to rescue Edris. Meanwhile, his teacher's body awaits the life-essence that can be re-instilled into him only by the joining-spell...if Ryel can find it. Even if he does, can the spell be made to succeed?

Or will victory go to Michael, Ryel's nemesis...and Lord Brother?
