The 2013 Nonfiction Reading Challenge was hosted by The Introverted Reader. I signed up at the "Dilettante" level (1-5 books), and read one book:
Darwin's Ghosts: The Secret History of Evolution, by Rebecca Stott
Not a great achievement - I really need to work more nonfiction into my reading routine. Still, I enjoyed the one book I read, and want to thank my host for giving me some motivation.
