Auggie (August) Pullman is ten years old. He has had twenty-seven surgeries—some big, some small—and he has some medical mysteries that doctors still haven’t figured out. All of this comes from a specific gene. His parents and his sister, Via, each carry the gene, too, but only Auggie shows it.
Because of his surgeries, Auggie was homeschooled for a long time but started going to a high school, where he did start showing his friendly heart and stop hiding behind his Halloween costumes.
