I am aware of the GT Goodreads and their February Book Club , and the suggestion for an NYC groupthink bookclub IRL, and wanted to point out that the Humble Bundle now sells audiobooks!

$1 (or as much as you want) in paypal or CC goes to Charity or Publisher (not sure about how much the author gets)

and you get

Salman Rushdie's the Satanic Verses, Lucy Christopher's Stolen, Meg Cabot's Abandon, William S Burrough's Junky, Margaret Peterson Haddix's Found, and paying above $5.92 nets you A Heartbreaking Work of Staggering Genius, Blood Meridien, and On a Pale Horse.
