One of the drawbacks of the ebook revolution is the lack of used bookstores. What was better than searching the shelves for second-hand bargain reads? You could walk out with a big bag of books for twenty bucks. Awesome! 
Fortunately, Brian James Freeman has made the hunt for ebook bargains a breeze. Check out these sites daily for free/cheap reads in the horror and mystery generes.
Will Castleton is US Marshall with psychic abilities, and David Bain is the community college English professor who created him. Both seem like interesting characters; Castleton with his sometimes-too-late “visions” of crime victims, and Bain with his ability to carve out a niche for himself in the self-pubbed crime fiction genre. Island Ghosts is a fast, fun Castleton adventure, and certainly a cut above the usual independent author offerings, and an excellent read for a freebie. Island Ghosts doesn’t have the most original characters or concepts, (there’s a ’80s television crime drama vibe running through this story that’s both cheesy and endearing) and the prose gets a bit purple at times, but Bain’s hardboiled style makes it work.
