His predictions for Islam are not wholly accurate. However, the reasoning by which he makes his predictions does seem reasonable, although he seems to view Islam somewhat myopically.

Unlike her other works I have read, this one ventures into bizarre racism with an emphasis on the "yellow peril." In this book's setting after World War I, that means Japanese immigrants in California, although all non-white groups in the US get a whack once somewhere in the book, with the exception of California's apparently extinct American Indians (they only appear in the past tense) who come off very well. The paranoid racism is truly ludicrous, but it does make a curious document of what was once considered acceptable thinking but thankfully is no longer.

One of the more interesting features of the book is how early and often slavery comes up. The CSA plantation owners frequently assume their slaves will willingly stay with them, but when they find that's not the case--either the slaves escape to join the Union forces or are forcibly taken and emancipated--they turn quite nasty.

I found it rather dull, but the description of everything is quite vivid. The hero's path from master practitioner of seduction to moral decay and the destroyer of another he "loves" as a proxy of a former lover is rather good, but the ending is so abrupt as to be dissatisfying.
