Three titles in the Pierre Chambrun series by Hugh Pentecost are $1.99 at Kindle and Kobo US today (Feb 23, 2021), and also discountable at Kobo. Some have been on sale before, and these are Open Road/Mysterious Press titles, so check carefully that you don’t already have these before you buy! I read a bunch of titles in this series back in paperback days and liked them, although I’m not really quite sure why. I think I liked the idea of the Beaumont Hotel as a city, or something…
