Sounds like a interesting idea. Let me start.
The Three Musketeers, By Alexandre Dumas.
What I found interesting is how little people have changed.
Greed, adultery, war, all bad things like that. Also some good
things the Musketeers showed. Love, pride, and caring about
others, even their Lackeys were treated well.
Of course every good book needs a antagonist. The cardinal
made a good one along with a female that would do anything
for his favor.
I best stop here. Don't want to give away the plot. It's a good
book for anyone that likes adventure stories.
