I've got good news and bad news. Since pulling my books from Amazon, I've looked around for an alternate venue, and the good news is that I've found one, Project Gutenberg Self-Publishing Press. More good news is that they're pdf ebooks, all free, and always will be.
And they're all here: http://self.gutenberg.org/Authors/KevinWadeJohnson
The following are already there, the others will join them when their Amazon-exclusive times end in mid-February:
Aunt Gabby Saves the Universe (novella)
Ghost Mode (novella) New!
Roads Between Worlds
Shadows Between Worlds
Across the Worlds with Aimee and Phineas
