If you’ve been watching the interviews about poltergeists on this site and YouTube, you will have seen me say that the ebook What is a Poltergeist? Understanding Poltergeist Activity was due to be published at the end of December.
Unfortunately due to a glitch in the space-time continuum this was not possible. The most up-to-date news from the e-gnomes in the vast underground complex of GeoffHolderVirtualWorld™ is that the book may be available at the end of January, but that depends on the deliveries of digital dragons’ blood arriving on time, so February might be a better bet. Apologies.
