I didn't care much for this story. It's got an awful lot of plot holes in it. The combination of water-wheels and navigable canals is one; the firearms was another (how did they come into being? where does the ammunition come from? why is a SENATOR walking around armed in an otherwise rigidly-placid society?). Unexplained -- and unexplainable -- feats of navigation. How the messenger-bird found him. And the people themselves seemed to sometimes have personality traits that challenged belief.
This passage --
Miss Ariel was learned in fire magic, she put a spell on my revolvers endowing them with the power of flame.
-- was so silly as to be almost cringe-worthy -- ALL firearms run on fire. I know, picky, picky -- just reword the thing. A hint, BTW -- if you're going to write about weapons, study their function, even if they are subject to magical spells. Get the real part real, first. Which reminds me; that sword-fighting aboard the gondola --
think about what might happen when two people plus some monsters are in a rather small boat, with one of the people swinging a sword around. It's a miracle the Senator didn't get cut and that no one fell overboard.
That said, I do encourage the author to try to make a novel out of this, provided that he's receptive to learning and constructive criticism. The process will certainly make a better writer out of him, maybe even a good one, if he's a good learner. I'll be charitable and presume that he's on the steep part of the learning curve at this point.
Taken from his bio:
I try to focus on creating original concepts and ideas while remaining less concerned with the textbook mechanics of a story." (Words to make a copy-editor's blood run cold...)
Actually, those are words to make a copy-editor's hand release a manuscript over the round file.
Learn the mechanics, Mr. Szabo. Your basic stuff (punctuation, spelling, grammar) isn't too bad; the
larger mechanics (of plot, mostly) need serious work.
