The Day The Crayons Quit is written by Drew Daywalt, and illustrated by Oliver Jeffers. One day, Duncan opens his box of crayons to find that it is empty - all the crayons have left! In their place is a stack of letters, one from each crayon, laying out their disappointment with Duncan and his colouring methods. Red feels overworked, pink feels underused. Black wants to be used to colour in more interesting things, and orange and yellow are arguing about which one should be used for the colour of the sun. Poor Duncan just wants to do some colouring, but he also wants his crayons to be happy, and so in the end he comes up with a colourful solution.
I enjoyed reading this book. It is very obviously an American book, although the spelling has been changed - there's no "coloring" here. There is also quite a lot of text to get through, so it's definitely better suited to older children that have the patience to sit still through the rather wordy letters.
