George Chryssides's publisher sent me a review copy of his new book, Jehovah's Witnesses: Continuity and Change. Expect a review after I've read it through twice or thrice. I'm on page 55 on the first reading. Up to page 55 this is a stellar generalist book. It puts to shame many of the earlier books treating this subject. I'll keep you updated.
So far I've found one minor grammar fault, meaningless. And one place where he would have benefited from our second book, not in print when his mss was finished. It is a very expensive book, but at page 55, and no further, I'd recommend it.
