I recently had a reader ask which of my books are available in paperback, and since that's a complicated question, I thought I'd post my reply here for others who are interested in paperbacks of my work.
Four of my books with Carina Press are available in mass market paperback: Come What May, Say It Right, As I Am, and Wild Trail. You can find them directly from the publisher or through Amazon and other retailers.
What You Own, Fractured Hymns, and Here For Us are available in trade paperback format from Amazon (What You Own should also be available directly from the publisher Dreamspinner Press, and other retailers).
All of my books previously with Samhain (the five Cost of Repairs books and the first three Perspectives) are still floating around on third-party sites, but availability varies as those are out of print in those versions. I'm currently working to get the full four-book Perspective books back out there in trade paperback on Amazon, and I hope to complete both Cost of Repairs and Us in paperback this year, as well.
The three paranormal novellas I'm publishing this spring will be available as a paperback bundle.
I hope that helps!
