The Guardian has helpfully compiled a list of the new releases:

I'm particularly excited about new books from Jon Ronson, Kate Atkinson (a companion volume to Life after Life), Jonathan Franzen and Sebastian Faulks. And David Lodge has a memoir out - am a big Lodge fan so really looking forward to that.
What about everyone else?
