Todays topic is -- Have you ever read a book that inspired you to take up a cause?  What book was it and what was/is the cause?

If you are talking about charitable or humanitarian causes, I would have to say no because I don't read those sorts of books.  I do read lots of history and historical fiction and I would say that those books -- can't really pick one out -- have lead me to be even more interested in history.  I read a lot of culturally religious things (Amish fiction, for instance) which makes me curious so I end up doing research on that and anything that will trip my genealogical trigger will set me off on a genealogical quest.
