Speaking up doesn't have to mean using your voice When Sara's little brother is born prematurely and has to stay in the hospital, Sara starts writing him letters. She tells him how her mom and stepdad are sending her to Toronto to stay with her half-sister, Abby. Sara has anxiety and selective mutism, so she has trouble talking to strangers. Luckily, Abby understands. Abby lives in a storage-container house on a vacant lot and hopes to build a whole community of them for unhoused people. When Sara sees that the mayor and the police are making things harder for people who need homes, she realizes she can be an advocate--through her letters--and that there's more than one way to speak up for what you believe in.
