I like Jack Higgins. The Eagle Has Landed is a good book, and was adapted into my favorite WWII movie of all time.
So I was doubly disappointed with the 2016 Sean Dillon book The Midnight Bell. It read more like a parody of Higgins than actual Higgins.
On the other hand, I recently cranked through 'The Little Paris Bookshop' and 'The Angel's Game' and both were pretty good, and have themes about the power of books to do good (or evil). Which is right in my sweet spot.
Medievalists and Medieval-adjacent. Sort-of.
