Maybe that is due to the fact that Hillary's book has been discounted up to 30% and maybe even more !! "Treason" wasn't on 'sale' when I bought my copy.
I picked my copy of Treason up today on my lunch break. I actually got it for 30% off at the Barnes & Noble here in Lakeland (FL). Annie's book was actually well-displayed, right up front on the bestsellers shelves, directly below the display of Her Heinous' bound pack of lies. To be completely fair, this is a very conservative area, so the B & N folks must know they can't get away with the "hide the conservative's book" antics they pull in so many other parts of the country.
Anyway, there were only three copies of Annie's book left (two after I made my purchase), while the shelf space reserved for the Beast was full! The clerk, who was very nice, said that Treason was flying off the shelves, and that she might have to read it herself to see why it was so popular. Warmed the cockles of my heart, it did.
Unfortunately, now I have to work the rest of the day before I can go home and start reading Treason - it's going to be a loooooooong afternoon.
