An emotionally resonant, visually stirring picture book illustrated by Pura Belpré Award–winning Abraham Matias, exploring life, death, and celebrating loved ones for children navigating grief. Inspired by the 9 levels of Mictlān and the role Xolo dogs play by guiding those who have passed on in Indigenous cultural understandings of present-day Mexico. Nana is surrounded by family and takes joy in her many grandchildren. She's also tired and feels pain. Soon she begins her transition from life into death, accompanied by her beloved Xolo dog, Popo. Together they go on Nana’s journey, and by the end of the story, Nana's family celebrates the many years of love they shared with her. And a grandchild will now care for Popo. Beautifully told by debut author Paloma Angelina Lopez and featuring stunning blend of colored art by Mexican illustrator, Abraham Matias, Popo the Xolo helps kids understand how loved ones live on in our memories. An unforgettable picture book that's grounded in the importance of the 9 levels of Mictlān and the role Xolo (show-low) dogs play in Indigenous cultural understandings of present-day Mexico.
