I loved
Mitch Rapp series, though only the originals, not those written by the ghost writers.
Jack Reacher is also great, but difficult to binge read as after a few books as they tend to take on the same story, so spread out the reading of that series. Save yourself the heartache, don't read anything after Lee Child handed over the reins to his brother.
Came across
Levon Cade a great series by Chuck Dixon. Discovered it after watching the movie A Working Man (2025) which was based on the first novel. 12 Books in that series and I struggled to put them down. They are only short novels between 35,000-60,000 words so relatively quick reads.

My all time favourite is a wonderful mix of thriller (Mitch Rapp style) and science fiction -
The Rho Agenda, by Richard Phillips. He has split them into 3 trilogies and recently started on his fourth trilogy of the same series.

Read in that order ^^
There is also the
Icefire trilogy, though goodreads only shows two books.

For stand-along books, try...
Nemesis by Bill Napier
Yea, I'll stop there, but plenty more suggestions if needed.
