Thanks for writing, and thanks for your kind comments about Unholy Sabbath. I am glad you enjoyed it. If you are so inclined, please consider posting a review on Amazon.
As for future projects, I am writing a history of Union veterans, tentatively titled When Billy Came Marching Home: Union Veterans and The Unending Civil War, which will chronicle the trials of homecoming experienced by blue coated ex-soldiers in the late nineteenth century. I am about half way through the first chapter now, but I hope to have this one out by 2014. Stay tuned. In the meantime, you can check out my blog, unionveterans.wordpress.com, which will have periodic updates about the project.
Thanks again for your kind words.
