I finished my third book of the readathon during this tenth hour: Swerve by Stephen Greenblatt. It was pretty good, but not what I expected. I expected that it would be more about the content and philosophy in Lucretius' De Rerum Natura, but instead it was about how the book was rediscovered by the "book hunter" Poggio Bracciolini during the Renaissance.
After finishing Swerve I started Snakes and Earrings by Hitomi Kanehara, a book picked on a whim from my public library's shelves. It promises to be a strange book.
