It's the perfect gift for the diehard Sons of Anarchy fan: a comprehensive retrospective book on the show! Except what if you ordered it, and it arrived before the series is supposed to end on Tuesday (10/9c, FX) and completely ruined the viewing experience they spent seven years investing their lives in? Oops!

The book Sons of Anarchy: The Official Collector's Edition, which covers the entire series including the yet-to-be-aired series finale, was accidentally mailed out a few days early, spoiling the ending of the series for those who flipped through the book. The book was supposed to hit bookshelves the day after the finale aired, on Wednesday.

Sons of Anarchy creator Kurt Sutter apologized for the mess up in signature fashion — with lots of four-letter words:

"It has been brought to my attention that our SOA Collector's Edition book has been sent out a week early by some distributors and book outlets. This book contains details about the final episode of the series. This, my friends, is a storyteller's worst nightmare. I wanted this book to be a complement to the show. It contains personal messages and photos from the cast, in-depth behind-the-scenes information and detailed breakdowns of episodes. It's a smart, well-conceived book that I was very excited for the fans to have. After the motherf—ing finale. There are a thousand f—ing people I can blame. And I assure you, by the time I am done, my f—ing basket will be filled with heads of incompetent c—s. But as far as the fans go, the burden is on me. I f—ed up. It was my idea for the book, so ultimately, I am to blame. So if you received a book, I apologize. I ask that you not share your wrath or pain or opinion in social media so as to not spoil the experience of others. There is no excuse for utter ineptitude. It pains me that this will be the parting memory of some fans. I hope you all tune in for the finale. It plays much better than it reads."
