He is reading The Canon: A Whirligig Tour of the Beautiful Basics of Science, by Natalie Angier. It was recommended by his ex-girlfriend. He was looking for a pop sci book that would give a more complete picture than the other pop sci books he was reading -- Cooked: A Natural History of Transformation, by Michael Pollan, and Gulp: Adventures on the Alimentary Canal, by Mary Roach. He is interested in reading about science, but doesn't like to read text books.
One of his favorite books is Blood Meridian, by Cormac McCarthy, which he just read. He also really liked Danny, the Champion of the World, a children's book by Roald Dahl.
