Kirkus Reviews - with the tagline "The World's toughest book critics since 1933" - have begun to drip-feed its best of lists onto their website, beginning with Fiction and Children's. Other lists, including Best Book App, will appear over the coming weeks.
So far I've only read four from the 2011 Best Fiction list - The Night Circus by Erin Morgenstern, The Magician King by Lev Grossman, Embassytown by China Mieville, and Open City by Tenju Cole. Although I have now put some other titles on hold for summer reading.
Of the four books, I would highly recommend both Open City and Embassytown.
