This was a difficult book for me to read. It clearly understands, and many times mentions, that the characters, the ideas, and even the book itself will likely be condemned by many as racist, prejudiced, and discriminatory. As a result, I will review it in two different streams of thought: once, as a fictional story in a mythical world, and secondly, as the premonition of the future that this book appears to actually be intended by the author.
A short summary: This book takes place several decades into the future on Earth, where the World Islamic State (Shiite-Sunni collaborated version of ISIS) controls many of the nations, leaving the remainder countries to bow and scrape as semi-subjugated nations before it. The premise of Land of Promise entails the formation of a brand new nation out of sliver of contested land in Africa, in order to provide refuge and safety for persecuted Christians worldwide. Think of Israel for Christian Libertarians, but without any particular holy or religious sites to the location selected, and a complete absence of taxes, licensing, gun laws or other forms of government. Tensions grow between the fledgling nation and the Islam-dominated world around it, and the story follows from there as one might imagine.
Let's start with a review of this book as a work of fantasy-fiction: If you simply replace the words 'Islam' or 'Muslim' with, say, a fictionalized evil bad guy term such as 'Orcs' (Lord of the Rings) or 'Empire' (Star Wars), and replace the term 'Christians' with a generic mythological yet religious group of people, does the story still entertain? Is the writing compelling as a fictional novel? When I separate away the portions that may be viewed as a discriminatory or prejudiced commentary of actual groups and peoples, what is left over is actually quite bland and boring. The characters and their development are shallow, with perfunctory and unrealistic reactions to the situations around them. The emotional connection between male and female characters, who have a habit of asking each other to court for marriage within a day of meeting each other, is wooden and awkward, like watching two mannequins attempting to waltz. The 'good guys' seem to do no wrong, contain very little complexity of emotion or character, and likewise are incredibly boring and interesting.
The Equipment, on the other hand, receives ten times as much attention to detail as any character does! I feel like the author doesn't actually have an understanding of how to write 'people' because he does not understand them, but has a superb understanding of machines, equipment, and (most significantly) weaponry. At numerous points I felt I was reading a manual for a new firearm I had purchased, or was watching a documentary on the benefits and downsides of various ammo types. As I previously have served in the military, I was able to follow most of this bizarrely meticulous delves that the author takes into the detailed workings of a particular jeep or magazine. But it is a terrible sign when the author thought it necessary to include a 50 page glossary to describe all of the obscure acronyms and terms used in this book (yes, that means over 15% of the book is Glossary). He clearly has a broad knowledge and understanding of the subject matter of warfare, logistics, and construction, but the endless segues into the workings of hydrogen-cell vehicles bogged down the actual plot too much of the time. The most interesting parts were the brief yet well combat scenes when terrorists infiltrate the newly formed country. But this was too little and too late to keep a reader interested. The author also has some interesting predictions about technological advances that I thought were intriguing, and so the descriptions of these post-modern weaponry and devices held a mild James-Bond-esque feel.
All in all, as a work of fiction, with any offensive connotations of it relating to the 'real world' removed, the book is unfortunately quite dull, lifeless, and entertaining only in the sense that a survivalist might love to hear about how to construct an underground bunker-home. The author would make an excellent non-fiction analysis I'm sure of 'how to clean and care for your G3 rifle', but he has no understanding of how to write realistic dialogue or hold together the flow and tension required for a story to maintain reader interest. If I was the editor of this book for some bizarre reason, it would be reduced in size by about 50% and still fully cover the actual applicable plot, as it were.
Now, unfortunately, I must address the book as it actually is meant to be: a clearly skewed and unhelpfully discriminatory view of the world, and a call to action of warfare between Christianity and Islam. Firstly, I am concerned about Jihadi terrorists and groups such as ISIS. But I also recognize that the world is a complex place, with many other factors at play, and that painting Muslims as 'enemy' with a broad brush is incorrect, irresponsible and provocative in all of the worst ways. The author clearly disagrees on this point. In his book, everything is black and white, with no shades of grey (like a Sith vs Jedi Star Wars struggle). All characters who are Muslim that appear in this book are cruel, angry, sinful, hypocritical (even the President of the World Islamic State is said in an aside to actually be non-religious and just 'doing it for the Power'!) and vengeful. Even more head-shakingly strange is that this world-conquering Islamic group is entirely incompetent when it comes to dealing with the newly formed Christian nations: all their assassination attempts are horridly botched (bombers blowing themselves up prematurely, or shooting wildly into the air with no fire discipline)...how the heck did they manage to conquer half the world at that rate??
Are some Muslims in the real world cruel, angry, sinful and hypocritical? Sure! Are some Muslims caring, generous, good-hearted, and faithful? Of course!! The author never bothers to ask the second question though.
On the other hand, every Christian character encountered in any real detail is caricatured as a hard-working, faithful, and absolutely obsessed with guns/rifles/weaponry. The most laughable line of all (paraphrased) is when the founders of the newly formed nation decide that no police form is needed, because this is a nation of Christians...why would we need police when everyone is a good Christian?
The best comparison I can make between this book and another would by Ayn Rand's "Atlas Shrugged" (though with the insertion of a heavy Christian presence, of course). A single quote for the billionaire Christian who finances the founding of this new state sums up the connection nicely: 'As they ate, some of the finches moved in...hoping to find some crumbs. Heston glanced at them and said, "Oh. Please don't toss them anything, or it will turn them into pests. Sort of like dispensing welfare."'
In conclusion, this book will be offensive to many people for its caricatured stereotypes and jingoistic overtones. If you are not a Christian Libertarian, you will not enjoy this book. If you ARE a Christian Libertarian, you still may not enjoy it as the story itself is poorly written, wooden, and awkward. The best you can hope for is to learn some in-depth knowledge on survivalist techniques, military technology, and fan your internal flames of intolerance in the hopes that by dividing the world further, it can be made better. That last point, sadly, appears the more likely result of books like this.
