I started writing as therapy, so David Rivers begins Greatest Enemy similar to me when I invented him- a former Ranger, West Point cadet self-medicating through writing and BASE jumping. And of course drinking.

Hellow Mr Kasper, just finished reading and reviewing all your American Mercenary books. Loved the lot. A question. The .454 Casull Rivers uses in the opening chapters of greatest enemy. A very interesting wildcat bullet. What made you pick it as his civilian sidearm as it's very unique and unexpected? https://www.goodreads.com/review/show/3057457111?book_show_action=false

Jason Kasper Thank you! I picked the .454 because I wanted something BIG and distinctive, and the .357/.44 seemed to be pretty common in both books and movies. As …moreThank you! I picked the .454 because I wanted something BIG and distinctive, and the .357/.44 seemed to be pretty common in both books and movies. As an original big-game tier weapon, the .454 seemed to check all the boxes for David Rivers.(less)

Quotes by Jason Kasper (?)

“Police succeeded by having protocol. Thieves succeeded by having none—at least, none that the outside world could decipher until after the job was done.”
― Jason Kasper, The Spider Heist

“No, son, you become a thing by being it first. There’s no room for wanting—the people who want a thing want it for their whole lives, always dreaming of another day. The doers in this world don’t want to be, they are. And they are in every moment, in every decision, every day of their lives. Now, what are you?”
― Jason Kasper, Avner
