These are all books I've read and really liked, not all of which have been read by my book group.
Middlesex by Jeffrey Eugenides (the current Opra book)
The Alchemist by Paulo Coelho
Bel Canto by Ann Patchett
Life of Pi by Yann Martel
The Kite Runner by Khaled Hossein
The Plot Against America by Philip Roth
The Secret Life of Bees by Sue Monk Kidd
Interpreter of Maladies by Jhumpa Lahiri
Without Reservations by Alice Steinbach
The Glass Castle by Jeanette Walls
Now none of the above is very recent. From my review pile, I liked Stephen King's new one, Lisey's Story, Con Ed by Matthew Klein, and, even though it didn't work for me, I could see it being a good book group book, The Crimson Portrait.
