The book is indeed as good as the reviews suggested. It's about a serial killer in a time traveling haunted house who kills young women from the 1930s to the 1990s. For each victim, we get a little bit of their life story in their unique decade before the gruesome and disturbing murder scene. The heroine -- the one who got away, but who is now kind of a freak because of the horrible scars he left her with -- is believable and sympathetic in her pain, and the supporting characters are good too.
A lot of the details of the time travel go unexplained. The chronology of the story jumps around across 7 decades. At the end, you are left with a 4 dimensional picture that to me was elegantly complete and better with the lack of details.
I left the book in Florida, to scare one of my daughters or daughter-in-law when they visit. Definitely recommended, 4 stars.
Addendum: I just finished "Salvage And Demolition", by Tim Powers. This is a novella in clapbook form I picked up from the library. It also was a nice, simple time travel tale that bites its tail and vanishes like the Beukes story does. A nice quick read.
I also recently liked the movie "Looper". I think it's maybe the best time travel movie I've seen, not sure why. But again, it is a pretty 4-d picture.
