It has a really good beginning as a drunken lout stops to relieve himself and gets a lot more than he bargained for. From then on we are introduced to the father and son. The writer did a good job fleshing out both characters and you definitely get a feel for their relationship. Likewise the secondary characters feel as though there is significantly more to them than is written. There is a very real sense that there is some backstory to these people.
The action is well written and there are points where you are not sure if the characters are going to make it.
It is a fairly gripping read, though short. The lightness of the text does not hurt the pacing, in fact should the book be lengthened, it would need re plotting as several of the scenes would feel out of place in a longer text.
All in all, an enjoyable quick read and I do recommend.
