There are several problems with this book which, while enjoyable and a fast read, still detract from it.
First, this is a follow-up to the book "Legacy of War" which came out earlier in the year and features Saffron Courtney, the major character in this one. So, we know she survives World War II. And, in "Legacy" she isn't married to the character she has a romantic fling with in this one; as a result, we know something happened to him.
Secondly, this and other books still being released under the name of the late Mr. Smith and a co-author are supposedly based on partial manuscripts and outlines he left behind at the time of his death. This one must be one of the ones done from an outline, because none of the writing reads like anything written by him.
Overall, what we have is a Wilbur Smith character and possibly a plot, written by someone else who tried their best to emulate his style, came close, but not close enough. That makes this one for the die-hard Wilbur Smith fan who wants to keep on reading about the Courtneys, and if you haven't read "Legacy Of War" yet, wait until you read this one, then go to it.
