What's a good book like the Robert Langdon series that follows a character(s) who follow historical clues and to treasure hunt or solve a mystery?
I'd read the Robert Langdon series, but apparently the reviews are terrible for it. It's inaccurate, the foreign language is terrible, it's poorly written, has bad plots, unexplainable and improbable physical situations, and sometimes just bashes religion, not even in an introspective or actually critical but just "meh Christianity is bad meh" boring preachy sort of way.

I know a good "historical" sci-fi book about xeno archaeologists travelling the galaxy, trying to find out what happened to an extinct alien race. It's called 'Engines of the Gods' by Jack McDevitt. No space battles or other aliens, just human scientists examining ancient alien relics mysteriously left for others to find. Very cool read IMO.

I'll jump to the Brown's defense. The problem people have is that they assume they're going to become some sort of historical genius by reading Brown's books, which a 5-minute Google search for practically anything in his books can put to sleep. So long as you aren't looking to learn anything or take anything away from his books, they're at least somewhat enjoyable - better as time-passers than anything else. Good airport reading material.
