Duet for Home by Karina Yan Glaser

At first, June can’t believe it: their new home is a homeless shelter? When she’s told she can’t bring her cherished viola inside, she’s convinced the worst luck in the world landed her at Huey House.
But Tyrell has lived at Huey House for three years, and he knows all the good things about it: friendship, hot meals, and the music from next door drifting through the windows. With his help, June begins to see things differently. Just as she’s starting to understand how Huey House can be a home, a new government policy threatens all the residents. Working together, June and Tyrell must find a way to save Huey House as they know it, before it’s too late.
