SO apparently The Cuckoo's Calling was actually written by J.K. Rowling
“I had hoped to keep this secret a little longer because being Robert Galbraith has been such a liberating experience. It has been wonderful to publish without hype or expectation and pure pleasure to get feedback under a different name.” J.K. Rowling said to the Sunday Times of London
But since this book has been out since April with only 139 ratings on Goodreads & 64 on Amazon, I'm sure at least the publisher was ready to spill the beans so they can make some cash!
Are you planning to read it?
