John is a good writer. I am glad you like his books. I will tell him I met someone who likes his books. He will like that. The Name Jack Campbell comes from John's Dad's first name and his paternal grandmothers maiden name.
I spent some time with John this past summer. I helped him and his brother Rob catalog his dad's gun collection and gave them an idea on how much each rifle, shotgun and handgun is worth. John is not very much into weapons for a retired Navy Officer.
It made me sad to think all those guns I used to shoot as a kid were going to be sold, including the government issue WWII era Colt 1911.
John Hemry is my first cousin on my dad's side. When I was a kid, I used to work on his dad's (My Uncle's) Wheat Farm in Central Kansas.
John has a new book in the Jack Campbell series coming out soon. He was working on it this summer but was having some trouble with the final battle at the end of the book. He has also been picked up for several more books. I have talked with him at great length about his source of inspiration for his writing and why he writes what he does. I can tell you this, he draws a lot of inspiration from his Naval experience. I think it is very cool that he has been able to make a living out of writing.
