Synopsis

After many centuries of plotting, the Sphinx, leader of the Society of the Evening Star, is after the final artefacts needed to open the great demon prison, Zzyzx. If the legendary prison is opened, a tide of evil is certain to take control of the world. Kendra, Seth and the Knights of the Dawn race to recover the remaining keys first, a quest that carries them across the globe and into the series' strangest places, while old allies are lost, prisoners are freed and the true scale of the demons' ambition becomes clear. In the series finale, allegiances are confirmed and secrets revealed as the forces of light and darkness collide in a desperate, climactic battle, at the shore of Zzyzx itself, to control the keys to the demon prison, and the children of Fablehaven learn what the five keys were really for.

Publication order and internal chronology are tracked as two separate orderings and are never conflated: a book's place in one says nothing about its place in the other.
