On the last page of the Caldecott-winning book Jumanji, young Danny Budwing is seen running after his brother, Walter, with a game tucked under his arm. Now after twenty years, Chris Van Allsburg is ready to reveal what happens when Danny and Walter roll the dice. This time the name of the game is Zathura and the battling Budwing boys are in for the ride of their lives.

Zathura unleashes intergalactic challenges that require even the quarreling Budwing brothers to work as a team.
