Since I've been on the topic of summer reading lists, it's appropriate to mention that O, The Oprah Magazine, has announced its 2009 Summer Reading List, titled 25 Books You Can't Put Down. Say what you will about Oprah's reading tastes, but her recommendations sell books. Lots and lots of them.
I'm currently reading her first pick, Let the Great World Spin by Colum McCann, and I'm enjoying it. Look for a review later this week here at Literary License. I've also heard good things about John Burnside's The Glister, though I haven't read it. Other than the McCann novel, I doubt I'll be picking up any of these.
