My library does a whole series of these bookmarks. If you like Tom Clancy, try Clive Cussler! So, one summer, when I had re-read my way through the entire Brother Cadfael series about a 12th century monk solving mysteries, and was looking for more, I picked up the “If you like Ellis Peters…” list.
NO, I will not like a book with crappy dialogue, minimal character development, and zero history just because it’s a mystery set in a medieval convent.
PS. I kinda trust Amazon’s approach a bit more—“people who bought this also bought…” no promises about liking, no attempt to guess taste, etc. Just a statement of fact.
