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 the trail to one of the remaining artifacts—a quest that begins in Grunhold, the domain of Fablehaven’s centaurs. If Seth can steal a closely guarded relic crucial to their quest, the Knights of the Dawn can continue on their path. But to succeed they must enter 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. Don’t forget to drink the milk.
