This rambunctious and big-hearted story of kindness—reminiscent of the Crayons and Cindy Lou Who—is written by the bestselling author of Ordinary People Change the World and illustrated by the Caldecott Medal-winning creator of Beekle.

Sunday quit, just like that. She said she was tired of being a day. And so the other days of the week had no choice but to advertise: "WANTED: A NEW DAY. Must be relaxing, tranquil, and replenishing. Serious inquires only." Soon lots of hopefuls arrived with their suggestions, such as Funday, Bunday, Acrobaturday, SuperheroDay, and even MonstersWhoResembleJellyfishDay! Things quickly got out of hand . . . until one more candidate showed up: a little girl with a thank-you gift for Sunday. The girl suggested simply a nice day—a day to be kind. And her gratitude made a calendar's worth of difference to Sunday, who decided she didn't need to quit after all.

When we appreciate each other a little bit more, all the days of the week can be brand-new days where everything is possible.
