The Pillars of the Earth by Ken Follet is a classic and a good read for factual history. It's settled around 1000 BC, when they were building cathedrals in Britain. It's less of a thriller than Da Vinci code, but still a page turner and way more plausible. Don't read too much about it or you'll have the ending ruined by spoilers. The motivations of the bad guys are plausible, so it's way better than Da Vinci imo.

If you're into Science Fiction, The Three-Body Problem by Liu Cixin is a good hard science book. The emotional intelligence of the characters baffled me (as it did in Da Vinci Code), but the book made me wonder in awe about the size of the universe and the nature of time. If you watched the Netflix show, they covered most of the first book and a part of the second (it's a trilogy). They just couldn't reproduce the astonishment I felt in the book when they talked about the actual three-body problem, and I feel the same will occur with the third book when they'll get there in the show.
