I remember a fiction book from when I was a kid about a boy who was raised in India by his father. But when his father died (and there was a part where I remember the boy going out on the river to dump his father’s cremated ashes), he ends up having to move to the US to live with his grandmother (I think). He was probably middle school aged? He struggles a bit to fit in, but then when his grandmother’s house ends up being threatened by a new highway going through, the boy convinces several of his classmates to come over to the house and they start a hunger strike that ultimately results in the house being saved. Some of those details may be a little shaky, but that’s more or less what I remember. Thanks for any help!
