Special Offer for Naval Order Companions


Dear Companions,
I will donate $2.50 to Naval Order of the United States for every novel you purchase from my website. Select a book (or books) and place your order. I’ll mail your autographed novel(s) the very next day. Free shipping domestic shipping within the United States.

Be sure to check out my latest novel, The Rhythm of Evil, along with my first novel, The Oath (awarded a Silver Medal by the Military Writers Society of America). 

Like all of us, Sarah and I are sad the 2020 Congress in Buffalo had to be cancelled. Let’s hope and pray the country gets back on its feet soon.
