Vince Flynn’s Mitch Rapp series.

Daniel Silva’s Gabriel Allon series.

Lee Child’s Jack Reacher.

Those three series ought to keep you entranced for a while.

“Vince Flynn’s Mitch Rapp series.”

I concur, an excellent series but best to read them
in the order that they were published.

I will try the books with Jack Reacher.
