Blossom, I am glad you are getting to do some recharging of your batteries. Good for you.
I done that before too, bought something and never got to it and then its free. Pretty much all books that are in the prime lending come up free at some point. I just been putting authors and books into the ereaderiq list and go from there.
The only prime books I have noticed that don't really go free are the ones put out by montlake. But indy published in prime usually always uses up the free days they have to use.
