Rianne and her siblings have lived all their lives overseas. When they arrive in an American suburb at the beginning of summer they know no one and there’s nothing to do. But there’s magical footprints in this house. Who excavated the tiny furnished room under the basement? Are there magical animals in Reston, Virginia?
A super cute re-released middle grade contemporary fantasy about a family moving to a DC suburb and discovering an opossum who can control luck, known as the Impossumble. It's a bit dated (it was originally published in 1992) but still very readable.
