OK, it seems that my local Indigo got Atonement, Sight Unseen and All That's Left in this week in one fell swoop. The only one of the recent MIA titles that wasn't there was Long Shot.
Was this some kind of strategy to delay stocking these as they were released, in order to have a bunch of new Trek books in at once for the holiday shopping season? Or just an oversight that they caught and corrected all at once? Or something else entirely? I have no idea.
I picked up Sight Unseen and All That's Left. (I had already got Atonement from Coles.)
Oh, they also had the new Costumes book, but I couldn't financially justify getting that one.
