This is a solid little slasher book. In the afterward Jon Athan points to Psycho and Texas Chain Saw Massacre as key influences and it very much shows. Both in plot points, locations, and situations. The ghost of Ed Gein flies high above.
All of this sounds awesome, right? And mostly it is. We follow a sweet couple, driving for business to Vegas through some long stretches of road that have spotty cell service. They find a car off the side of the road that has the passengers slaughtered. Clearly not dead from the accident the car appeared to have, but from violent cuts all over them.
This sets up a situation where our couple finds themselves in the crosshairs of a killer. Some locals share details of urban legends that suggest there may be more murderers involved than the one they know about. Their situation just got exponentially worse. Who can you trust? Who else is involved?
So, let's talk Texas Chain Saw Massacre and Psycho - both rather tightly wound stories with small casts. Butcher Road fits this as well. TCSM and Psycho are also rather bloodless. Their fear comes from suspense. Jon Athan is a talented writer and he can charge up some suspense. But, expecting suspense to the level of two of the finest films of all time? That's unreasonable. His bread and butter is disturbing, gory, brutal stories. Here's where things stay good but don't rise to excellent to this reader. With such a small cast of characters you can't really do this. In the afterward, it's clear this was intentional, that adding random characters that the reader is indifferent to only to provide a body for slaughtering was not what he wanted to do. A noble writing experiment, but it limited him from using one of the best tools in his toolbox. But once he gets to the titular "Dinner Scene", he makes up for lost time and the "extreme master" is back to show how it's done.
So, all in all, this is a good book. Good characters, some suspense, and it's short enough that even if it takes a while to get to the brutal tale that readers were expecting, it's not an unreasonable length. Hell, this may be a great introduction for a King/Koontz reader who wants to dip their toe into Jon Athan's more "extreme" bibliography.
