Hello,
Both Soulstone and Dragonstone will be on sale on amazon.com from December 21st (8AM PST) to 28th (12AM PST).
If you are still looking for something to read during the holiday season, then you could start with these. And since they are Kindle editions they are easy to take with you if you need to travel.
Merry Christmas and Happy Holidays.
Yours,
Tommy
