The Guardian has a Summer Short Story Special, where they feature a few new short stories by known authors.
Because I am predictable, I'm going after A. M. Homes' The Neddy Silver Story and Jeanette Winterson's Message In A Bottle ("Message in a Bottle" Is that the best title you can come up with, Jeanette? It's so Hollywood-Kevin Costner!) first.
Then I'll check out the others if I can find the time.
