Plagues of night at the Prophet's door

David R. George III has updated his Facebook page to clear up details of the recent listings of a TNG novel by him called At the Prophet's Door. As suspected this is indeed the first book in his forthcoming 24th century duology. But rather than being the new title for the book it was a place holder, and the working title previously announced, Plagues of Night, is still the one George is using at the moment. You can read the full explanation on the author's Facebook page; where he also noted the TNG classification might not entirely accurate either.
