Charlotte Austin has spent her entire life trying to ignore the dead. Unfortunately, the dead refuse to ignore her. Ever since she was a child, Charlotte has been able to see ghosts-a talent that has cost her jobs, relationships, and any real hope of living a normal life. Spirits drift toward her with unfinished regrets and desperate requests, treating her like an unwilling messenger between worlds. The only place they cannot reach her is her small apartment. Until one day, something does. This particular ghost breaks nearly every rule Charlotte's grandmother ever taught her about the dead. Spirits aren't supposed to cross blessed thresholds. They aren't supposed to wander far from where they died. And they definitely aren't supposed to look so confused about it. Which raises a troubling question: If this ghost shouldn't be able to enter Charlotte's home-but somehow can... What exactly is she? As Charlotte becomes reluctantly entangled in the mystery of the strange woman haunting her apartment, the line between the living and the dead begins to blur. Because this ghost is not like the others. She doesn't beg for help. She doesn't remember how she died. In fact, she doesn't even know how a ghost is supposed to behave. She's nothing like any spirit Charlotte has ever encountered. And Charlotte never expected this one to change everything. It should have been a simple haunting. But nothing about this one is simple-especially when the confused, slightly too polite, mostly innocent ghost keeps saying: "I'm a good soul." Charlotte realizes-far too late-that she might be dealing with something far more complicated than one very strange ghost.
