About ten to fifteen years ago there was a guy who self-published/ reprinted Angels and Women (with some modifications) and had it for sale on Lulu. I don't recall his name, but for some reason he credited me (or rather a webpage I had authored) in helping him to identify the author of Seola. She was Ann Eliza Brainerd (Mrs J.G. Smith). I think she was deceased by the time the Bible Student reprinted and revised it as Angels and Women. The republished Angels and Women was a thinly disguised advertisement for Russell's Studies in the Scriptures, with numerous footnotes directing the reader to the Studies.
As a youngster I used to read all kinds of science fiction, and the SF of the late 1800's was kind of fanciful to modern readers, but Seola was not unusual for the time. In my opinion, Mrs. Smith's fiction fell into the SF genre of the pre-1900 time period and was simply that, works of fiction.
