Aided by relatives that she hasn't seen since she was five, Kerra learns of a secret passageway to a tropical world in 19 A.D.  Intensified by an earthquake, this time vortex threatens to draw all modern characters into a massive battle between a tribe called Nephites and ancient sorcerors known as robbers of Gadianton.  Their only hope may reside with an alert, intense young Nephite warrior named Kiddoni, who understand what it takes to forestall certain destruction, and keep it from descending upon Kerra's family, and their small western town.
