Grandma's Window

Every day on the bus to school, new student Mateo stares out the window, wishing he had a friend to talk to . . . until one morning, when he spots something surprising in an apartment window-an older woman is smiling and waving to the bus!
For the next few weeks, Mateo and his classmates wave to the nice lady they lovingly nickname "Grandma," and she always waves back. But one day, Grandma is missing from her window, and she's not there the next day, either. Mateo and his classmates must work together to find Grandma and make sure she's safe and happy.
Grandma's Window is a story of friendship and kindness that shows us that no matter how young or old you are, the best way to bring joy into your life is to give it to others.
