BOOK FIVE OF THE BELOVED FABLEHAVEN SERIES--OVER 3.5 MILLION COPIES SOLD! AND DON'T MISS FORBIDDEN MOUNTAIN, THE START OF BRANDON MULL'S NEW GUARDIANS SERIES!

Celebrate the 20th anniversary of the beloved New York Times bestselling series about two siblings who inherit a hidden sanctuary for magical creatures. In the explosive finale, time is running out to stop an army of demons from being unleashed on the world.

Hours of crisis often call for sacrifice.

After centuries of plotting, the Society of the Evening Star is closer than ever to opening the great demon prison and unleashing a tide of evil. And when the enemy strikes even closer to home--kidnapping Kendra and Seth's parents--it kicks off the epic final showdown between the forces of light and darkness.

While racing across the globe to secure the remaining artifacts with the Knights of the Dawn, Kendra and Seth are separated in the thick of battle. Kendra's search to rescue her family takes her across time and space, from the Fablehaven of the past to a preserve so hidden that few even know of its existence. Meanwhile, Seth's path brings him face to face with the Sphinx--the mastermind behind the Society--who gives Seth a dangerous choice that could change everything.

Allegiances will be tested and secrets will be revealed in a desperate battle to control the keys to the demon prison--and control the fate of the world.
