The House at the End of the Road by Kari Rust

There's an old house at the end of Grandma's road.  When the two siblings and their cousin walk down, it looks vacant.  When the cousin throws a rock at a window, they see a ghost looking at them.  They tell Grandma about the ghost and she tells them that's just the old man who lives there.

Owlkids Books and Net Galley let me read this book for review (thank you).  It will be published September 17th.

Grandma goes with them and they visit the old man.  His house is filled with a treasure trove of fun things for children.  The attic has board games.  There are books and old records.  They have a good time visiting and often go back.  But one day the house is put up for sale.  He's sick and in a home and they will sell the house to pay for his care.  Their summer is coming to an end but they will never forget that old man and the fun they had visiting...
