Sparkie,
My novels are Flank Hawk, and it's sequel, Blood Sword. They're mainly available online (print and ebook formats) but they can be ordered from brick and mortar bookstores. It's very unlikely you'll find one just sitting on the shelf. Here's a link that might be helpful:

What's the name of your book? I seem to remember seeing the title, but I can't remember what it is. I'm between books right now, and I was thinking of picking yours up. Where is it available?
