I really couldn't decide whether to rate this a 2 or a 3. It was very gory, but then when you're writing about serial killers that's to be expected, just be prepared for a squirmy read. It was free on kindle and the ending was good, so both of those points counted in its favor.
That was my original review of this and I'm sticking to it. However, having read some of the other review blasting it, I feel the need to defend it. This is a horror novella, it was made blatantly obvious to any readers. In the first review (I have to admit it's kinda cheesy for authors to give their own books 5 star reviews, it should have been added to the book description instead), Kilborn/Konrath writes, "But just because it is 100% free doesn't mean you should automatically download it. This is disturbing stuff. Perhaps too disturbing. If you can handle horrific thrills, proceed at your own risk." Obviously many people ignored this little piece of advice. If you don't like horror, if you can't tolerate gore and squirminess, why did you download this? Why would you want to read a novella about serial killers? And why are you so surprised that they're sadistic people who (shocker!) kill people? Seriously, it's not like they sugar-coated it to lure you in. This was free and you were warned. Sure, it's sick. As a longtime fan of horror writing it even made me squirmy. But I finished it, and I have to tell you it ended very well. Which brings me to my next rant...
Why would you review a book you didn't even finish? How can you say it was irredeemable if you didn't even read to the end. Maybe, they killed each other horribly, maybe they got arrested and punished for their crimes, maybe the next victim killed them both in self-defense, you don't know, you didn't even read the whole thing! I don't like horror movies, and the premise of Saw and the other torture-porn films out there disgusts me. But I don't go and write reviews about how much they suck either, and I don't rate them poorly because I've never watched them. (To the reviewers who did read the whole thing and still gave it a horrible review, please, don't think this is aimed at you, you have earned your right to complain.) There are quite a few books that I've tried to read in the past and couldn't finish, but I don't go around telling everyone they sucked.
Go ahead, write whatever you want, it's not like I can stop you, but seriously think about it. Did you pay for the book? No. Were you adequately warned in the description? Yes. Did you even read the whole thing?
