I discovered this author a couple of years ago, she's not got many out so far.
Cal Leandros series
there are three books out for this series, and its a bit like Supernatural - two brothers PI's doing supernatural jobs
the brothers are a lot different though and their exploits quite different too
She's just started a new series
The Trickster
Only one book out for this so far, its OK, about a Trickster god that is stuck in human form and fighting demons. I enjoyed it , but i prefer the Cal series
