These three books are on the freebie list from Christian publishers. The Abingdon ones always return back to full price in a few days, so be sure to download those right away. These titles were not available free on Nook when I checked last.
A Simple Amish Christmas by Vannetta Chapman (Abingdon Press)
Christmas is Not Your Birthday by Mike Slaughter (Abingdon Press)
Hurry Less Worry Less at Christmas Time: Having the Holiday Season You Long For by Judy Pace Christie (Dimensions for Living)
