It is said the mighty feathered serpent god, Quetzalcoatl, helped create the earth. He is the hero who stole back the bones of humanity from the evil god of the Underworld. In his quest to bring humans to the earth, Quetzalcoatl's dog-headed twin brother, Xolotl, was present. Not much is known of Xolotl, the god of lightning, death, and misfortune. A monster.
This is what really happened.
From Newbery Medalist Donna Barba Higuera and illustrator Mariana Ruiz Johnson comes a singular reimagining of the Aztec myth of the origin of man—and man's best friend—that is nothing short of a modern masterpiece.
