Not sure how best to review this. It's a very dark story, but the author gave abundant warnings of that. I have to respect any author that explores difficult themes, in a literate way. Having read his "Truckers Adventure", I am comforted that he can write of positive, if sad, characters.
There's no distracting sex, so I considered both the writing, which is fine, and the science fiction, where I had some problems in suspending disbelief. First, I couldn't really accept that there was a unique "Middle Eastern" genome that could be targeted for genetic effect. Second, if the target was Muslims, they aren't all Middle Eastern. Third, it bothered me to see an emphasis on modifying both DNA and RNA.
While the errors aren't huge, it could use a copy edit. Only guessing, though, this may be the result of DormDad needing to get a difficult story out.
