When Sally O'Brian visits the library, two ghosts overhear her conversation and realize that she might be their salvation.

Loretta Grey has been stuck in the Loretta Grey Memorial Library for the past seven to eight decades...and now she and her fellow ghost want to be free.

Sally O'Brian, ex-school teacher, untimely widow, and near-death survivor can speak to the dead. But this ability has come with a cost.

Sally O'Brian has to find a way to get the dead to pass on to their eternal resting place. But to do that, she has to solve two murders, a few years apart, both of which happened eighty years earlier. Okay, that would be difficult, but how hard could it actually be?

"First," drawled Matt, her dead husband, "you might have to get them to be nice to each other."
