It is wrong that these books, the entire series by Lucinda Riley, are characterized as "fantasy." At first, I was afraid to get them because I thought they were science fiction since they refer to the myth of the Pleiades, but in the end, they have nothing to do with that. The sisters in the book series simply took their names from the myth of the Pleiades, and that's where any other reference to unreal events ends. So if that worries you, don't think about it, get the whole series, the writing of the much-missed Lucinda is classically very beautiful.
