Book:The Shepherd's Crown

In an email received on the 3 July 2014 from the Discworld Emporium a 5th Tiffany Aching novel was reported:

NEW BOOK ANNOUNCED! - On Tuesday Terry confirmed via Twitter that he is in the midst of writing a 5th Tiffany Aching Novel, stating that "we don't know when it will be published because we don't know when it will be finished" and that "Yes. Granny is definitely in it". Along with hundreds of thousands of Discworld fans, we've been floating on a cloud of elation ever since, eagerly awaiting the return of our favourite Wee Hag.

A note from Penguin Random House on Mar 12, 2015 states that "he completed his last book, a new Discworld novel, in the summer of 2014, before succumbing to the final stages of the disease".

The Toronto Star (an unlikely but usually reliable source) says the title is to be The Shepherd’s Crown. This title was confirmed by an announcement by Transworld Publishers in the U.K. and they have told the Guardian that there is not set date as of the 18th of March 2015.
