Giving Up the Ghost by Sheri Sinykin

Main Character: Thirteen-year-old Davia
Location: Louisiana
Time period: Contemporary
Genre: YA Fiction, Fantasy, Ghosts

When Davia and her parents go to the old plantation house at Belle Forêt to take care of Great-Aunt Mari, Davia expects to see Tara. What she finds instead is an old, neglected house which is downright spooky. Great-Aunt Mari has moved out of the old house--can't handle the stairs anymore--and has been comfortably furnished with a hospital-style room in the old stables. Uncomfortable with the dying old woman and worried about her own mother, who has just recovered from cancer, Davia is easy prey for Emilie, the nineteenth-century Creole ghost who refuses to leave her old home.
