This story is dedicated to anyone who ever wanted to change the world, but felt their actions were too small. To anyone who ever dreamed of being a real-life superhero. And to anyone in search of sunshine and lighthearted fun. Meet the 16-year-old Rose Channing, author of “The Mansion’s Twins,” before her authoring days. Before she knew for sure that magic existed. Before she even knew her own middle name. Before any of that, there was an annoying freshman girl following her around. A girl who talked too much and sang too loud. A girl with a silly but sweet idea to turn ordinary high school students into heroes. Before Rose became Rose, there was Dawn.
