I like that - "A Kindle Full of Lemons." I think that the good SPAs (and there are a few) get around by word of mouth. I remember an obscure little title 2 years ago - Angelfall - A bunch of us loved and spread the word about the book.
Sadly, it's not just the SPAs. I picked up a new-to-me Kindle freebie this morning published by "Wild Rose Press." Not that I'm unfamiliar with them, but for cryin' out loud, how do they get away with calling themselves publishers?
...and I've (thankfully) just started reading a wonderful, gripping story by an SPA! After so many lemons, it feels wonderful to read a well-written story, no glaring grammar issues, excellent story line. Review to follow as soon as I'm finished...
