Grave Surprise by Charlaine Harris (Harper Connelly Book 2)

Ever since Harper Connelly was stuck by lightening as a teenager, she’s been able to find dead people. At the request of anthropology professor Dr Clyde Nunley, Harper and her stepbrother Tolliver head to Memphis to give a demonstration of her unique talent in an old cemetery.

Dr Nunley is sceptical when Harper senses two bodies in the grave – one of a centuries-dead man and the other of a young girl, recently deceased. Then the grave is opened. The dead girl is eleven-year-old Tabitha, abducted from Nashville two years previously – a child whom Harper had tried, and failed, to find. Suspicion falls on Harper, so she and Tolliver must prove her innocence by finding the killer themselves.

But time runs short when a third body is found in the same grave. . .
