The history presented is incredibly inaccurate and full of lies, anachronisms, and Islamic propaganda.
The author's intention is obvious - to lie about Coptic history, creating the impression that the Bashmuric revolts weren't Coptic revolts, but ones that were initiated by Copts and Arabs alike, against unfair rules that persecuted both groups. Of course, this is untrue.
In her novel, only the later caliphs deviated, but the earlier caliphs were just and merciful. This is another lie.
She draws an image where the Copts warm-heartedly welcomed the Arab invasion, Islam and the Arabic language. This is yet another lie.
She also claims that the Copts weren't Christians but pagans, which is yet another lie.
Besides all of these lies making up her "conquest propaganda" work, the novel is full of ridiculous anachronisms.
This work is outrageous conquest propaganda. I would sue this person if she were in a country that had more respect for human rights.
