I'm the New York Times and USA Today bestselling author of more than sixty-five books of military urban fantasy and supernatural thriller fiction, including the Templar Chronicles series, the Jeremiah Hunt trilogy, the Great Undead War series, and the HELLstalkers series. My work blends the firepower and camaraderie of military fiction with monster hunting, secret orders, and occult warfare — a good fit for readers of Jim Butcher, Ilona Andrews, Larry Correia, and Jonathan Maberry. I've also written several books in the Rogue Angel action/adventure series from Gold Eagle.

I'm a former president of the Horror Writers Association, the world's largest organization of professional horror writers, and a multiple Bram Stoker Award and International Horror Guild Award nominee.

When I'm not writing, I'm hanging out with dogs, practicing recurve archery, or off-roading in the desert around my home in Phoenix, AZ.
