New Yorker cartoonist and bestselling author Bruce Eric Kaplan depicts the catastrophic and humorous consequences of sibling rivalry in this companion to Monsters Eat Whiny Children.

Henry and Eve are two perfectly delightful children—who fight about absolutely everything. (They’re siblings, after all.) Their latest sibling spat is over an action figure. Which means it’s serious.

Before too long their house is destroyed. The park is leveled. The whole neighborhood…gone.

Can anything repair this rift? Or will their bickering be the end of the Grand Canyon? And Texas? And the universe?
