If words make up the stories and letters make up the words, then stories are made up of letters. In this menagerie we have stories made of words, made FOR all the letters.

The most inventive and irresistible book of the year spans a mere 26 letters (don't they all!) and 112 pages. From an Astronaut who's afraid of heights, to a Bridge that ends up burned between friends, to a Cup stuck in a cupboard and longing for freedom, Once Upon an Alphabet is a creative tour de force from A through Z. Slyly funny in a way kids can't resist, and gorgeously illustrated in a way readers of all ages will pour over, this series of interconnected stories and characters explores the alphabet in a way that will forever raise the bar.

In Once Upon an Alphabet, #1 New York Times bestseller Oliver Jeffers has created a stunning collection of words and artwork that is a story book, alphabet book, and gorgeously designed art book all in one.
