Graveminder (Graveminder Series, Book 1)

Rebekkah Barrow never forgot the tender attention her grandmother, Maylene, bestowed upon the dead of Claysville. Now Maylene is dead and Bek must go back to the place--and the man--she left a decade ago. But what she soon discovers is that Maylene was murdered. It turns out that in placid Claysville, the worlds of the living and the dead are dangerously connected.
