Charles and Emma: The Darwins' Leap of Faith by Deborah Heiligman

I've been listening to this story on audio book and enjoying it in snatches here and there.  I do not know how much of what is written is fact or fiction.  However, I am convinced that if Charles Darwin had been alive in our times, he would have been a blogger, and in so doing may not have revolutionized the world with theories of evolution.  He was certainly a person who liked to write his thoughts and wanted others to read them so maybe he would have published - who knows?  At any rate I'm convinced he would have been a blogger!
