In many ways, the Hamilton children are like any other kids. Eleven-year-old Mia and ten-year-old Will love playing Minecraft, eating pizza, and playing in the yard. But Mia knows that because Will is on the autism spectrum, some things are different for him. For starters, he doesn't like things to change. Pizza has to be just so crispy, or he won't eat it. He uses lines from movies to answer most questions. If his toast is too dark, Will could have a total meltdown. When Mom and Dad announce they're getting a babysitter for the first time, Mia is alarmed. What will happen if the babysitter doesn't understand the unusual things Will does? Her parents know that she is Will's "translator" because she always understands him. Can they manage a whole night with a brand-new person in charge? Is it always Mia's job to worry, or can she find a way to rely on other people? Toast explores the tender, scary, funny, and always complex relationship between a girl and her autistic brother.
