Safari is an action packed thriller spanning several countries in Southern Africa involving hunting, poaching and the 'darker elements' that could conceivably surround those activities. With most of the action happening in Zimbabwe and the Democratic Republic of Kongo and plenty of firefights throughout, one may definitely get the impression that Park does a good Wilbur Smith style African thriller.
As most of his other books, there is a romantic story there somewhere, as well as an educational component informing of the plight of the continent in some form. Most of it will be pure action, though and one can only say that the author does a very good job of that aspect. On top of writing a well flowing text, the research is also properly taken care off, so you will not find howlers that would lessen the enjoyment of the book. The only thing that may shock certain readers is the topic chosen, which while fictional, could well be imagined to be true - and in that case pretty chilling.
In spite of the complicaion in the book becoming apparent fairly early on, I would also not say the telegraphing detracts significantly from the enjoyment you would derive from it. The only aspect one could criticise is that the author does not seem to build storylines around specific characters / families that would span several books (at least not on the basis of his work I have read so far). This means one off novels, which is not a problem per se but leaves a bit of room for maneuver, given that all his books deal with similar topics in largely the same geographical area.
Overall I can only recommend the book to readers who are both into thrillers and into Africa. Wilbur Smith fans will find an author, who while not quite at the same level as the old hand at his peak, certainly beats the last (apparently ghostwritten) efforts from him hands down.
