“Sons of Anarchy” fans devoted enough to purchase the new behind-the-scenes book “Sons of Anarchy: The Official Collector’s Edition” were rewarded for their love of the FX biker drama by having the final episode of the series spoiled for them.

The book was released ahead of its Dec. 10 scheduled date by certain distributors. It contains a ton of information about the show including plot details about the finale, which won’t air until Dec. 9. As a result, those who got their hands on the book early had the series ending ruined for them.

“This, my friends is a storyteller’s worst nightmare,” series creator Kurt Sutter said in a colorful apology to fans.

Entertainment Weekly reports the book’s publishing house, Time Home Entertainment, released a statement saying that the distributors violated a strict embargo placed on the book’s sale date. Unfortunately, there seems to be nothing they can do about it now that the details are out.

"While extremely disappointed, we are very proud of the book, which is a wonderful tribute to the show,” the statement read.

While Sutter claims there are “a thousand f---ing people” he can blame for the end plot being leaked early, he tells fans that he is taking full responsibility for the mishap.

“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," he said. "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.”

This isn’t the first time this week that a popular TV drama dropped a major spoiler bomb on millions of fans. “The Walking Dead” had to apologize for posting a spoiler photo to its official Facebook page after the show premiered on the East Coast. Although the photo was almost immediately taken down, many fans on the West Coast had the midseason finale ruined for them.

Those who are still in the dark about what will happen after the exciting penultimate episode of “Sons of Anarchy” can tune into the series finale Tuesday, Dec. 9 at 10 p.m. ET on FX.
