I’ve put in the cover versions of the copies I have. Order To Kill was the point where I was up to speed with the paperback releases and have got the hardback versions from there onwards. The UK covers are the ones pictured and have been consistent (in a Jack Reacher kind of way). Anyways up, they are streets ahead of the US versions.
The first book here, Term Limits doesn’t involve Mitch Rapp, but is set in the same world as the Mitch Rapp books, and several of the characters reappear in later books.
As the back cover of the paperback says: The first gripping thriller from international bestseller Vince Flynn, Term Limits is the utterly compelling precursor to the Mitch Rapp series.
