A completely run-of-the-mill fantasy story, Heroing probably isn’t worth your time.  I found it annoying to read and only finished it because I forgot to put anything better in my bag.  Be warned that I’m not bothering to put a spoiler barrier in, simply because I don’t care enough.  You’re not going to read this book, right?

Actually, some of the story is interesting in concept, like the Jiana/Jianabel split personality, but the execution is horrid.  The characterization is particularly bad; I had a difficult time believing in any of the major characters, especially in the professed love between Jiana and Dida.

And the afterward reveals that the author had a pro-feminist goal for the book (which was published in 1987).  Good books with political or social subtexts are fine—such things can enhance a well-written volume.  Bad fiction written to advance a particular viewpoint is often among the worst writing around.
