Sure, the glass castle floating over Evan’s head is unsettling, but that’s the least of his worries. With each step inside the Dungeon of Dreadful Dreams, he must battle against his worst nightmares. One after the other, wispy smoke-filled bull sharks come at him — he must remember they’re only illusions pulled from his imagination by those dreaded shadowlike hands. If only the vengeful dragon circling above was also an illusion and didn’t have his mind set on destroying the one person who can control him: Merlin.
Inside the castle’s glass tower, Merlin sleeps in an eternal slumber, and Evan’s uncertain whether he can save the great wizard. Especially now that Merlin's former student, the Lady of the Lake, has joined forces with the cunning immortal Alamaz. Together they have already stolen the Dragon’s Egg, but their greed doesn’t end there. The Siren’s Pearl calls to them, and that means only one thing … Atlantis is in trouble.
Join Evan, Claire, and Dunkle — along with a few other unlikely heroes — as they travel across the realm of Medieval Legends, float through the Ancient Isle of Avalon, plunge inside the Dungeon of Dreadful Dreams, and be there when Atlantis rises once again.
