This is an extremely short story (only takes up 20% of the Kindle ebook download). It was very well-written, and interesting. My problem with it was that I really didn't understand it. DID the guy go back in time only to warn the killer of what he was about to do? Or was it all just a mind trick and the good doctor was feeding him these horror fantasies all along, knowing he was going kill the family? Nothing's really explained after you realize who exactly the psycho murdering fiend is. He's just there with his crowbar and that's it. End of story. I think if it would have been a little longer and a little more detailed, it would have been a lot better.
Also, there are two sneak previews of the author's novels in this edition. There are 7 chapters of Malice and 2 of Bird Of Prey. I read the first three chapters of Malice, very interesting and creepy stuff, but then I discovered that one of the main characters is Wiccan, so that was a no-deal for me...time to quit (for the reason that my faith in Jesus is my life and anything occultic in nature has no place near me). Moving on to Bird Of Prey, that was also well-written and interesting, but contained too much language for my taste.
