ALVIN HO IS an Asian American second grader who is afraid of everything—elevators, tunnels, girls, and, most of all, school. He’s so afraid of school that, while he’s there, he never, ever, says a word. But at home he’s a very loud superhero named Firecracker Man, a brother to Calvin and Anibelly, and a gentleman-in-training, so he can be just like his dad.
