Bastian Balthazar Bux is shy, awkward, and certainly not heroic. His only escape is reading books. When Bastian happens upon an old book called The Neverending Story
, he's swept into the magical world of Fantastica - so much that he finds he has actually become a character in the story! And when he realizes that this mysteriously enchanted world is in great danger, he also discovers that he has been the one chosen to save it. Can Bastian overcome the barrier between reality and his imagination in order to save Fantastica?
