Kyle Mills and Mitch Rapp
I was given a book for Christmas. “Lethal Agent” by Kyle Mills. The bio says he and his wife live there in Jackson Hole, Wyoming. Three hundred and ninety pages which I just finished. Pretty easy reading. There is another author whose name is on the cover....Vince Flynn. 1966-2013. Story follows an ex-CIA agent turned contractor who uses his training to chase down Isis leader Halabi who intends to unleash a super virus on the west. I suspect the original author created the Mitch Rapp character and the Kyle Mills guy has written some more stories in the style of the original author.
Anyway. Pretty good reading.
