Scott Nicholson has a bunch of books on sale. Scott was a writer I discovered when he was issuing his books as paperback originals from Kensington.
I haven't read all of his books, but enjoyed those I read.
The Solom Trilogy is on sale for $0.99 a pop. These were originally released as a single book: The Farm, though looking at the page count on here, the story was greatly expanded. The three individual books are:
The Scarecrow
The Narrow Gate
The Preacher
He's also collected some books and short stories into a series of books with a Door theme. These collections are $0.99 a piece and are a very good deal:
Door To Evil - This collects the short stories Speed Dating with the Dead and The Dead Love Longer and the novel Drummer Boy
Door To Fear - Collects the novels The Home and The Red Church and the short story Burial to Follow. The Red Church was his first published novel.
Door to Chaos - Collection of Kiss Me or Die, Playin' Possum and Meat Camp. Not sure which are stories and which are books. I haven't read any of them yet. Meat Camp sounds like a hoot.
