Little Yuki and her older brother Shen are far from friends. Yuki has big feelings, and Shen has little patience for her stomps and tears. One afternoon on the walk home from school, Yuki, in a fit of rage, flings their house keys into the sewer. When she climbs down after them, she comes face-to-face with the Muddy Majesty of Muck: an ooey, gooey creature made entirely of mud. The Muddy Majesty takes Yuki on a journey underground, meeting Boogers who love to be mean, and trekking to a museum of objects left behind by those who lost their tempers once, too. Along the way, the Muddy Majesty explains that the meaner Yuki becomes, the bigger she grows. Yuki feels like she’ll be stuck underground forever, but then she spots Shen, who’s come to her rescue. The siblings reconcile, Yuki feels her anger melt away, and although the Muddy Majesty has now shrunk, Yuki promises to come back and visit her soon—to make mud pies, of course.

Alemagna’s incredibly charming illustrations, created through an endearing and eclectic potpourri of gouache, collage, oil paint, and wax pencils, make Her Muddy Majesty of Muck just as delightful visually as it is in its storytelling. The dialogue is simple yet incredibly effective, and the humor—snarky Boogers attempting to read or bathe or don heels and a muddy princess who can’t stop dripping—will appeal to younger and older readers alike. Most importantly, the story’s message resonates: we shouldn’t let our feelings consume us. Anger, envy, and sadness can be messy, but with persistence and love and maybe a nice shower, even the muddiest of feelings can eventually be washed clean.
