Well, it seems that the Christian Fiction publishers are putting out the freebies for the US post-Thanksgiving weekend.
Some of these titles also showed up free earlier at Amazon or Kobo, but it looks like not all have individual threads yet, so I'll put a round-up below for convenience.
Also, a secular NOOKcolor kid's freebie is 
Twelve Hidden Days of Christmas, and the various holiday Samhain romance offerings (their B&N books are for some reason DRM-free, so will work on Sony or Kobo too) listed in the post with the Free Fridays paranormal 
Battle Sylph still seem to be free, as is the Free Fridays holiday bonus B&N Classics illustrated and annotated 
Grimm's Fairy Tales.
