Lilly, Henkes’s peerless princess of mouse perfection, is absolutely certain that she is a shoo-in for the role of flower girl when her beloved teacher Mr. Slinger announces his impending nuptials. Lilly throws herself into preparations with her typical enthusiasm. When she discovers that she will not be the star flower girl, but only an apprentice to Mr. Slinger’s niece, Ginger, she valiantly struggles to adjust to her new role. However, when Ginger is frozen by stage fright, Lilly naturally saves the day with élan that surpasses the most seasoned red-carpet celebrities. Henkes manages once again to present Lilly in all of her wonderful, flawed glory, and readers will continue to love her dearly for it. In between giggles, they’ll get a Lilly lesson in handling disappointments with aplomb. As always, Henkes’s illustrations perfectly capture every delightful nuance of Lilly’s persona whether she’s practicing aisle-walking “in something more appropriate” or announcing her intentions to the universe. With Lilly, it’s always a big day. (Picture book. 4-8)
