The forest heaves and splits in a terrible quake, and
Griffin, a newborn Silverwing bat, is sucked down a fissure
deep into the earth. Shade, Griffin's father, soon realizes
that his son has been drawn into the Underworld and embarks
on the most dangerous of journeys to rescue him. Shade knows
he must find Griffin quickly -- legend says that if the
living stumble into the land of the dead, they have only a
short time before death claims them, too. But something else
is hunting Griffin -- a deadly foe Shade hoped he would
never see again. Who will find Griffin first?
