There’s something weird about that mirror in Granny’s attic!
Orion and her brother Ollie see the reflection of a girl who isn’t really there. Not only that, she looks like somebody from another time. With neighbors Sal and Sofi Martelli, they learn the story of Susanna Chase, a slave girl who ran away on the Underground Railroad in 1860 and waited in Quindaro for her father to join her. She died of the measles before he got there, but she can’t “die satisfied” until she finds out if he escaped from slavery. The kids seek help from Granny, who reveals a long-buried secret. A diary, a doll and a harmonica lead them to answers for Susanna, but they’re almost out of time—they have to tell her before she goes back to her grave forever! The bonus? An amazing connection that nobody expected.
