I actually do do that and we all recommend each other older stuff we read years ago. :)

These are some of my most recent conversations: "try Raymond Feist's Magician series" "I'm reading the Book of the New Sun series now" "I read the Pendragon Cycle (she's English and obsessed with King Arthur stories) in high school and liked it but now it's a weird right-wing tv show"

These are all old books but still super enjoyable. (Except maybe book of the new sun - kind if a bummer)
