Now twenty years later, Chris Van Allsburg is ready to reveal what happened when Danny and Walter rolled the dice. This time the name of the game is Zathura, and the battling Budwing boys are in for the ride of their lives. Soon Zathura unleashes intergalactic challenges that require the quarreling brothers to learn how to work together as a team.
