Robert Galbraith or JK Rowling?

Sometime in April a mystery crime novel called The Cuckoo's Calling has been released under the name Robert Galbraith. However, on Saturday July 13th the secret slipped and revealed that Robert Galbraith the author doesn't exist. The true author of this novel is none other than J.K. Rowling herself. This news was not meant to be revealed until much later and it wasn't on Rowling's request. The news slipped from someone Rowling believed she could trust. Due to this unfortunate incident bookstores have sold out. 300,000 more copies are to be reprinted, but this time with Rowling's bio in the back. If Rowling had her way, the bookstores would already be stocked with the prepared number so the selling out could be avoided. Barnes and Nobles will be re-releasing the copies in four weeks and on Rowling's request have held the Casual Vacancy till the 23rd of July. The covers are shown below with UK version first and US version second.
