I have found that I enjoy reading series more than stand alones. These are some of my all time favorite series and reading order for each.
Three Sisters Island by Nora Roberts
Dance Upon The Air, Heaven and Earth, Face The Fire
When I picked up this series I was only reading straight romance, mysteries, thrillers, etc. This got me back into paranormals and I found a world that had grown exponentially since I had last read one.
