Trouble Pug is scheduled to be free Friday and Saturday, September 1 and 2.
Notes From Hiding in serial format will be free in stages September 12 through 15. This time, just to try something different, the parts will be offered in reverse order. Isannah Here and To Whom It May Concern are scheduled for Tuesday, Dear Neighbor for Wednesday, and Dear Citizen and Dear Invader for Thursday and Friday.
These will be the last Kindle free deals for the foreseeable future.
Also, these books will leave the Kindle Unlimited program when the current Amazon contract for each of them ends (September 16 or 17). The good news is that after they leave Kindle Unlimited, they can be restocked in ebook in non-Amazon markets around the world again.
