From Sibert Award– and Pura Belpré Medal–winning creator Duncan Tonatiuh comes a highly original fable inspired by Mexican folk art

The city of Mousetepec is a lively place filled with color, music, and alegría (joy). But everything changes one night when the shadow of un gato appears, growing larger and larger until it looms over the whole city. Fiestas are cancelled and the mercado empties as the cat terrorizes the townsfolk.

To save their town, two little mouse siblings—Vida and her brother, Máximo—make a brave plan to scare away the cat after a bright, fantastical creature called an alebrije appears to them in a dream.

Acclaimed author-illustrator Duncan Tonatiuh presents this imaginative fable that will encourage young readers to confront any “shadows” they may face in their lives with a spirit of courage and alegría.

Includes a note on alebrijes, the inspiration behind this fable, glossary, pronunciation guide, and bibliography
