Despite myself, I am intrigued…
First off, if you own a Kindle (or use the Kindle app on your $DEVICE), you should probably read Pixel of Ink. It’s one of my favorite, “Oooh, cheap or free Kindle books!” lists. Though it still has its share of romance novels (because, really, numbers lean heavily that way), it seems to make an effort to include other genres that are often overlooked by some of the other bargain listing sites.
Like, this book, for instance:
The first volume in The Oz Chronicles recalls both Stephen King’s The Stand and L. Frank Baum’s The Wizard of Oz.
For free, it might be worth picking up, based upon that description alone.
