Zathura is a 2002 science fiction children's picture book written and illustrated by American author Chris Van Allsburg.

The two quarrelsome brothers each desire opposite activities; Danny wants to play catch, while Walter wants to watch television.

Danny concludes that they must finish it in order to return home, so they continue playing.

The robot chases the creatures away as Walter takes his turn and gets pulled into a black hole and sent back in time.

[3] A film adaptation of the book titled Zathura: A Space Adventure was made in 2005, directed by Jon Favreau.
