Otherworld Chronicles: The Invisible Tower (Paperback) (ISBN-13: 9780062070883)

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.
