Buying and moving into the run-down Jewel Motor Inn in upstate New York wasn't eleven-year- old Miriam Brockman's dream, but at least it's an adventure. Miriam befriends Kate, whose grandmother owns the diner next door, and finds comfort in the company of Maria, the motel's housekeeper, and her Uncle Mordy, who comes to help out for the summer.
But when it becomes clear that only a miracle is going to save the Jewel from bankruptcy, Jewish Miriam and Catholic Kate decide to create a Virgin Mary apparition at an abandoned drive-in theater. The Jewel instantly fills up with guests, including Anton, whose mother doesn't seem to understand that using a wheelchair doesn't mean he wants a miracle. Miriam must deal with feelings of guilt at having faked the apparition, and happiness at all the good things the new tourist site has brought to the community.
In the end, a shocking incident of anti-Semitism threatens her new home as well as the growing friendships within the Jewel's diverse community. And unless Miriam finds a way to resolve all the hurt and fear, the No Vacancy sign will come down for good, and she will lose the life she's worked so hard to build.
