Hi Peter, yes, same book. Those are both early working titles. There will be almost no overlap with the Hobbit Chronicles, bar perhaps the occasional quote or image, but I would estimate 2-3% at most. The focus of the book is world-building, so the emphasis is on building the environments, something we didn't really cover much in the Chronicles. It will also be more than twice the number of pages of the biggest Chronicle and cover all six Middle-earth films. Thanks for asking!
