In this stunning wordless picture book, a lonely girl draws a magic door on her bedroom wall and escapes into a wondrous world where she creates what her adventure requires with a red crayon.

When she frees a caged purple bird, she is captured by a sinister emperor who throws her crayon into the abyss. This time, it’s the purple bird who lends a hand.

In an ending that’s sure to speak to readers of all ages, we learn that behind the purple bird, there’s a new friend with a purple crayon—the girl’s collaborator on this imaginative journey.
