What book would you post on a map?

Hi makers, I'm launching Literary Map https://www.producthunt.com/posts/literary-map where you can post moments from your books on a map and follow them around the world. I began obviously with Around the world in 80 days, because I love Verne´s books and the story happens in many countries, which would help me exemplify the use of the application. But what other books would you use whose story covers many countries?
