There is a new kind of book, however, that has been
appearing with more frequency on the science fiction and fantasy
bookshelves since the mid-1960's. Instead of clearly defining
which of the two genres it belongs to, this new kind of book
merges the two, developing its own plot and scene with
borrowings from both genres in a new kind of melting pot where
the results are never the same twice. This new book is science
fiction, because it includes all or some of the traditional
elements of science fiction: new technologies, travel to and
among the stars, the inquisitive and rational scientific
mindset, and all the other conventions of science fiction.
However, since it also includes conventions like swords and
magic (especially psionic magics), feudal structures and
societies, and different ways of understanding the universe that
are not limited to the scientific paradigm, it is also clearly
fantasy.
Several names have been proposed for the new, blended genre, but as of yet, none of the names have done it justice. Several critics have called it "science fantasy," blending the two names,but that term has not been adopted wholesale, because so many different types of blends still exist. There are now, however,several common denominators to describe classes of this blended genre, into which many of the most popular hybrid series fit.
