Nestled in the mountains high above the storms, in the tower city of Urithiru, Shallan Davar investigates the wonders of the ancient stronghold of the Knights Radiant and unearths dark secrets lurking in its depths. And Dalinar realizes that his holy mission to unite his homeland of Alethkar was too narrow in scope. Unless all the nations of Roshar can put aside Dalinar’s blood-soaked past and stand together—and unless Dalinar himself can confront that past—even the restoration of the Knights Radiant will not prevent the end of civilization.
