J A Konrath is the author of 'AFRAID' - albeit under the peusonym of Jack Killborn - and the 'Jack' Daniels series of crime thrillers. Aside from this he is also one of the most succesful and innovative authors concerning ebooks which, despite many authors' reticence to accept, is going to be huge in the future and may well replace traditional publishing before we know it. There isn't much that Joe - that's his name - doesn't know about publishing ebooks, or for that matter writing and publicity, so if this is an area of interest to you, why not take a look over at his blog 'A Newbie's Guide to Publishing'. From there you can surf to his website, where you can download free ebooks, or buy some if that's your wish. Alternatively you can just glean some amazingly good advice from his writing tips. Well worth a few minutes of your time, I bet.
By the way 'Afraid' is just about the most intense horror/thriller I've read in years and his ebook 'Serial' is an awesome novella that is guaranteed to give you a buzz. (you can download it at his site).
