Kristy and the Secret of Susan (the Baby-Sitters Club #32) - Ann M. Martin
America's favorite series returns with a new look and a Netflix TV show. \n\n \nKristy's newest baby-sitting charge is Susan Felder, who goes away to a special school. Susan isn't like most kids. While she can play the piano and sing beautifully . . . she can't talk to anyone. Susan is autistic. She lives locked inside her own secret world.\n \n\n \nKristy thinks it's unfair that Susan has to be sent off to school and is treated differently from everyone else. But Kristy's going to try to change that -- by showing everyone that Susan's a regular kid, too. And then maybe Kristy's new friend can stay in Stoneybrook for good.\n
