From the publisher:

From the team who brought you The Fantastic Flying Books of Mr. Morris Lessmore comes an alphabet tale extraordinaire

Once upon a time there was no alphabet, only numbers…

Life was…fine. Orderly. Dull as gray paint. Very…numberly. But our five jaunty heroes weren't willing to accept that this was all there could be. They knew there had to be more.

So they broke out hard hats and welders, hammers and glue guns, and they started knocking some numbers together. Removing a piece here. Adding a piece there. At first, it was awful. But the five kept at it, and soon it was…artful! One letter after another emerged, until there were twenty-six. Twenty-six letters—and they were beautiful. All colorful, shiny, and new. Exactly what our heroes didn't even know they were missing.

And when the letters entered the world, something truly wondrous began to happen…Pizza! Jelly beans! Color! Books!

Based on the award-winning app, this is William Joyce and Moonbot's Metropolis-inspired homage to everyone who knows there is more to life than shades of black and gray.
