Sparkle Moore is destined to be a star. Her mother is determined to turn her into a social media influencer and superstar. But at the onset of middle school, Sparkle begins losing her hair - first her lashes, then her eyebrows, and then bald spots appear in various sections on her head. It's hard enough having to go to school and hide her diagnosis from her friends, but Sparkle quickly has to deal with weird medications, itchy wigs, and lost opportunities her mom has wrangled, including a big shampoo commercial. Despite everything she might do to hide what's happening, Sparkle has to come to terms with the changes in her life and show her classmates and her family what she can do with or without hair.
