The Summoning by J. P. Smith
Fake medium Kit Capriol reads the obituaries every morning, looking for potential clients. Her own husband was killed in the Twin Towers on 9/11. She knows all about grief and the hope that it would be possible to communicate with the dearly departed and, although she can't seem to get an acting job, she's very good at convincing her clients that she's receiving messages from beyond the grave.
I've got mixed feelings about this one. At first I didn't like Kit at all, but as I got further into the book I realized that everything wasn't quite what it seemed. By the middle chapters I was really enjoying it, then by end end I wasn't sure what to think.
