Like I indicated I can't see anything odd. I even changed case, deleted and retyped etc...
Code:
These two have an error u'\u2019'
Death of a Valentine - M. C. Beaton
Another Man's Moccasins - Craig Johnson
These two have an error u'\u2014'
Kindness Goes Unpunished - Craig Johnson
Angelic - Kelley Armstrong
Update: This was a good use of the Temp Mark plugin.
