BOOK THREE 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 third book, darkness is threatening to overcome Fablehaven—and all the magical creatures within it.
Strange things are afoot at Fablehaven. Seth discovers that someone—or something—has released a mysterious plague of darkness that infects magical creatures and transforms them into monsters. As the disease spreads and the dark creatures attack, the Sorensons are desperate to find a cure. But to triumph over the darkness, they may have to uncover the hidden history of Fablehaven—and their own family.
Meanwhile, Kendra and members of the Knights of the Dawn must journey to a distant preserve to retrieve another hidden artifact, but only if the Society of the Evening Star don’t get there first. Far from home, they will have to face traps, traitors and even a dragon to complete their quest.
With both siblings racing against the clock and enemies around every corner, they will have to decide who to trust and how to embrace their emerging powers to save Fablehaven.
