Plenty of disgruntled UK readers have been in touch about the long gap between the US and UK releases. It's unfortunate and hardly ideal, but it's just one of those things, I'm afraid. Scheduling issues meant that the UK edits couldn't be completed until last month, whilst the US publisher had always planned to release the book this month. And before you start, I know it's the same book, but each publisher releases their titles in their own house (and geographical) style.
You could always console yourself by watching the AUTUMN MOVIE again and venting your frustrations by yelling at the screen. It's on the UK Horror Channel at 2:20am on Wednesday 21st March.
