GC, I read the Harper Connelly series awhile back and I enjoyed it too. It took me a little bit to get into it, but once I did I loved it. 4 books is perfect for that series. The last book was especially good.
Have you read the Lily Bard books? That's actually my favorite series. I haven't read her other series. The Lily Bard books aren't super natural at all. They're mysteries. The first starts out a little slow, but once it gets going, I think the series is great.
I think CH is a really good writer. The Sookie books have just dragged on too long.
