“THY KINGDOM COME is a scary, prescient thriller that confronts us all with the very real possibility of an attack on the U.S. from the inside instead of the out. Don Helin’s taut tale of one brave man confronting white supremacists with plans to outdo 9/11 is reminiscent of the best work of Stephen Hunter and Vince Flynn.”
–National best-selling author Jon Land

“THY KINGDOM COME crackles with authenticity.”
–Best-selling author CJ Lyons
