It's been a while since I have made a Sunday Suggestion, but I LOVE the Bishop/Special Crimes Unit series by Kay Hooper. I just recieved the lastest novel form the library the other day, and read it all that day. I couldn't put it down for long.
I started reading the series actually on the fourth book, which started the second trilogy set. Then I went back and read the first trilogy while waiting on the fifth book to the series. Luckily, all the books are written to be stand alones (more so than others), although reading them in order is advised.
The books are:
Hiding In Shadows
Out of the Shadows
Whisper of Evil
Sense of Evil
Chill of Fear
Sleeping With Fear
Blood Dreams - JUST published, available only in hardbound
Blood Sins - not yet published/written
Blood Ties - not yet published/written
