Secrets of the Dragon Sanctuary

OVER 3.5 MILLION COPIES SOLD IN 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 fourth installment of this worldwide phenomenon, they must face dragons, giants and demons before time runs out to save the world.

Two hidden artifacts have been found. Three more remain hidden. If all five fall into the wrong hands, they can unlock the great demon prison and unleash unstoppable chaos and destruction on the world.

After escaping a close call with the Society of the Evening Star, Kendra uncovers a clue to find one of the remaining artifacts. To follow the trail, the Knights of the Dawn require a key closely guarded by Fablehaven’s centaurs—and Seth may be the only one who can steal it. But even if he succeeds, the quest leads straight to a death trap: the dragon sanctuary of Wyrmroost.

Wyrmroost contains threats unlike anything anything Seth and Kendra have faced before—terrifying creatures, perilous challenges and heartbreaking betrayal. To survive and claim the artifact before the Evening Star, they will have to learn to trust their new magical abilities, and trust each other.
