Lilly's favorite teacher, Mr. Slinger, is getting married, and Lilly is going to be his flower girl! Well, Lilly, thinks she is going to be his flower girl. It turns out that Mr. Slinger's niece Ginger is the official flower girl. But Lilly rises to the occasion as only Lilly can, turning heartbreak into wedding cake (a delicious three-tiered frosted Swiss cheese, no less), and disappointment into friendship!
