J K Rowling writes an adult novel!

I thought J.K. Rowling had retired for ever from her writing. Far from it..She now comes back with an adult novel. What hubris! But no doubt her book would sell by the bucketful, given the gargantuan marketing that goes with Rowling products (books).
I suspect in years to come people will make a link between our plump, comfortable, infantilising society and the popularity of Potter.
