Something terrible, unspeakable, boundless came to Menzoberranzan, leaving death and destruction in its path. The Forerunner of Gauntlgrym stirs, sending Catti-brie and Gromph to Luskan, to the ruins of the only power that can keep the creature in check. And Drizzt is going home. But not to Mithril Hall. Not to Icewind Dale. His path lies in Menzoberranzan. Bruenor is willing to go with him—taking an army of dwarves with him—to end the drow threat, but Drizzt must see what is happening there. Maybe an army of dwarves won't be needed. Perhaps the City of Spiders has already fallen to the demons and their unholy prince. But even if so, where are the guarantees that the demons will stop there?
