Hercules, Robin Hood, and Pecos Bill all come magically to life! But, heroes aren't the only characters in stories. Villains, too, are affected by the magic spell and soon the children find themselves in a race against time to reverse the spell as evil characters from all of literature threaten to take over the world! Their only chance lies with the heroes they've brought to life. But even that may not be enough to stop the Frankenstein Monster, Baba Yaga, and the Wicked Witch of the West!
