Harris Charlaine. Grave Sight

Harper Connelly Series
Grave Sight is the first of four novels in the The Harper Connelly Mysteries by American mystery author Charlaine Harris. Harper Connelly, the central character of the novel, has the ability to sense the location and last memories of dead people, a result of being struck by lightning as a young teenager.
Harper Connelly has what you might call a strange job: she finds dead people. She can sense the final location of a person who's passed, and share their very last moment. The way Harper sees it, she's providing a service to the dead while bringing some closure to the living - but she's used to most people treating her like a blood-sucking leech. Traveling with her step-brother Tolliver as manager and sometime-bodyguard, she's become an expert at getting in, getting paid, and getting out fast. Because for the living it's always urgent - even if the dead can wait forever.
