Heppner's book about a major war between a powerful China and an America that isn't just declining, but actually down and on the mat shows all the problems that give indie books a bad rap. I'll touch on each of them:
1) Terrible research. Heppner doesn't bother to reference Chinese military equipment using Chinese terms. Instead, he uses Russian. He is apparently ignorant of everything the United States military has developed in the last 15 years, let alone has in testing, and therefore has no concept at all of what even a weaker near future American military might look like. Instead, he relies entirely on late Cold War legacy systems. He can't even get basic historical details, like what happened at Pearl Harbor, or the basic geographic details of his Alaskan setting right.
The book is literally built on a foundation of factual errors. It's really, really ugly. No one who calls themselves a fan of mil-tech or military history should approve of this crud.
2) No proofreading. The book is riddled with typos, spelling errors and grammatical errors.
3) Knee-jerk political agenda. Heppner apparently doesn't understand that if you are going to put a political agenda in a book like this one, you do it sparingly and subtly. Instead, his vision of the future packs it with anti-Democrat fantasy propaganda guaranteed to offend... what, 1/3 to 1/2 of his audience? Even if some love him for it, at least as many will be turned off.
4) Wooden characters. And to get back to point #3, almost all the Americans are basically WASPs.
Once you know all of this and you realize that Heppner is rapidly turning books out at the rate of at least three per year -- he has multiple series running concurrently and just this one saw five volumes released in the space of three years -- one can only draw the conclusion that Heppner has zero respect for the craft of being an author. He doesn't think his books through, he does zero research, and he obviously publishes his first draft with a minimum of editing and no proofing.
By the way, while I know these books sold well, Heppner claims to be a "best-selling author." As far as I know, he has never broken the Top 100 on any major publishing list, let alone into the Top 25.
