Ophie's Ghost by Justina Ireland

The New York Times bestselling author of Dread Nation makes her middle grade debut with a sweeping tale of the ghosts of our past that won’t stay buried, starring an unforgettable girl named Ophie.

Ophelia Harrison and her family used to live in a small house in the Georgia countryside. But that was before the night in November 1922 and the cruel act that took her home and her father from her. Which just happened to be the same night that Ophie learned she can see ghosts.
