Catherine O'Flynn's looks the most interesting from the write-up.
The thought of the AN Wilson makes my heart sink, as do all the others set in the 1940s. (I've always struggled with war books - "Atonement" is my least favourite McEwan.)
Lots of them are so young though. Nikita Lalwani is only 33. I read recently that the average age of New York Times bestseller list writers is 54. That seems a bit more realistic. Most novelists produce their best stuff in their 50s and 60s, surely? You have a lot of tricksy show-offy stuff to grow out of at 33.
Kiran Desai's book, which won last year, may be a masterpiece for all I know, but I'm not going to read it because she seems such a giggling girlie in public.
