for the five artifacts. To this end, Kendra, Seth, and the Knights of
the Dawn will venture far beyond the walls of Fablehaven to strange and
exotic magical preserves across the globe, where the end of every quest
becomes the beginning of another.
In this explosive series finale, allegiances will be confirmed and secrets revealed as the forces of light and darkness collide in a desperate struggle to control the keys to the demon prison.
