The battle for the fate of the world comes down to a desperate race against the Society of the Evening Star. For centuries, the demon prison Zzyzx has kept the darkest evils safely locked away. Now, the Sphinx and his followers are dangerously close to collecting the five hidden artifacts needed to open the gates and unleash absolute chaos. When Kendra and Seth's parents are kidnapped, the fight becomes deeply personal. The siblings must team up with the Knights of the Dawn, venturing far beyond Fablehaven to explore exotic, highly guarded magical preserves around the globe. Separated in the heat of battle, Kendra must travel through time and space to rescue her family, while Seth faces a terrifying choice presented by the Sphinx himself. You will join them on this explosive final mission, where secret allegiances are tested and massive sacrifices must be made. The forces of light and darkness will collide, and Kendra and Seth must risk everything to secure the keys and save the world.
