Upon going through the final product my editor let me know of a large discrepancy between this book and first that had been somehow missed leaving a large plot hole as well as an inconsistency. It is entirely my fault, somewhere along the line wires were crossed in my brain, but this means I need to do a mass rewrite to address it involving at least three parts of the book and many scattered throughout in various references. I could do a rough clean up, but honestly, this is the last book, I want to go out with a bang, not a whimper. I want to deliver a polished product and not one where the patches were quickly slapped on. And trust me, I tried to find a way to salvage things, but there is no way to salvage it and give a product to everyone that I could be proud of and you would enjoy reading. I am having to push back the release date to Dec. 17st to not only re-write several chapters, but to also allow my editor time to edit them and address anything that might crop up. The public release will be on Dec. 30th after I have been assured that any and all hard copies are in the hands of people who have preordered. This is going to allow a good amount of grace time to make sure everything that is rewritten is done so properly, re-edited and put together again without any chance of further set backs being placed on it.
I apologize, deeply and truly. I have labored over this product for quite some time (longer than I should have) because the ending of the trilogy is supposed to be the best of the best, the finale filled with battle and fire. I want to deliver on that promise and not something that does neither myself nor my readers a service. I will refund anyone who wants one from the preorders with absolutely no hard feelings, I know that this is unexpected and many have eagerly awaited getting the copy in their hands. I truly hope that this will be worth the wait for those who have followed our adventures.
TL;DR Late findings in the book means a large rewrite that interferes with the release date meaning we will have to push it back in order to make sure the book is properly finished.
