Thirteen-year-old Daisy Woodward loves insects, running track, and hanging out with her older brother, Sorrel, who has Down syndrome and adores men's fashion. When her social studies teacher assigns each student a project to change the world for the better along with an oral report, Daisy fears the class bully -- who calls her Woodworm -- will make fun of her lisp. Still, she decides to help Sorrel fulfil his dream of becoming a YouTube fashion celebrity despite their parents' refusal to allow him on social media. With the help of her best friend Poppy, and Miguel--the most popular boy in school and her former enemy -- Daisy launches Sorrel's publicity campaign. But catastrophe strikes when her parents discover him online along with hateful comments from a cyberbully. If Daisy has any hope of changing the world, she'll have to regain her family's trust and face her fears of public speaking to find her own unique and powerful voice. Daisy Woodworm Changes the World includes an author's note and additional resources.
