It's pretty difficult for me to read just one book at a time. I didn't allow myself to start 1Q84 until I finished reading Freedom. (And it took me hella long to finish Freedom because I was jumping around various literary digs while reading it.) Needless to say, I haven't shed my two/three-book-at-a-time habit, but I'm accepting that it's my preferred way to read. I'm currently reading Haruki Murakami's 1Q84 and Jay-Z's Decoded. If there's one thing that these two books share, it's amazing (and amazingly similar!) book design. Take a look-see.
