I get the brochure through the door from Bibliophile Books every so often. The title of this one caught my eye as it's about end of the world beliefs. It has a section on JWs. Interestingly they've put it in the New Age and Occult section and not Religion.
The blurb reads in part:-
'As the author wittily remarks: 'The End is (Often) Nigh!' Human beings seem to be obsessed with predicting that their time will soon be up.......
For the Jehovah's Witnesses, it has constantly to be recalculated.'
