Otherworld Chronicles: The Invisible Tower

In Artie Kingfisher's world, wizards named Merlin and fire-breathing dragons exist only in legends—until the day his favorite video game, Otherworld, springs to life. You are special, Arthur, says a mysterious message in the game. In one week's time you will come to me at the IT. Cryptic clues lead Artie to a strange place called the Invisible Tower, where he discovers he is actually King Arthur, brought to life in the twenty-first century. Artie has already conquered the virtual Otherworld—now it's up to him to save the real Otherworld as well. Magical dragons, hungry wolves, and powerful sorcerers await as Artie and his sister, Kay, embark on a quest worthy of the Knights of the Round Table.
