Planet Earth has been taken over by a very noisy noise in this humorous, colorful story by award-winning Brazilian author and illustrator Guilherme Karsten.

A gigantic noise makes its way around the world, knocking the stripes off a tiger, flattening mountains, and rallying all of humanity to respond. What could it be? An alien invasion? A meteor that crashed into a foghorn factory? A saxophone extremely out of tune? Where is the noise coming from?
Both children and parents will relate to this funny tale of the boo-boo heard round the world in this English-language version of an award-winning book originally published in Portuguese. Filled with eye-catching pencil sketch, collage illustrations, Aaahh! draws readers into the mystery of the overwhelming sound-and its amusing origin.
