I think the main Heroines name should be Miriam, especially if you want to add effect to her seeming ‘normality,’ paired with her surname, Wolfhart, gives a sort of suspense to the idea that one would suspect that she has something strange about her (and her family) with the Victorian house and ‘accident.’ Genevieve i belive would suit her twin quite nicely. And Leo Sullivan, sounds pretty darn good and cool and fits his stereotype. It also gives him a down-to-earth vibe that you seem to etch out for us, as I am suspecting he will eventually fall in love with her or something.
Yeah, I have to say I’m quite surprised and intrigued by your style of writing. You seem to be an amateur, but Don’t Give Up! I’m a pretty good and precise critic, so belive me when I say that I suspect you of having a lot of talent. Work away at your craft and never stop looking for inspiration being a writer and do the best that YOU can do to improve your skills. There’s something about this small piece that has caught my attention. I’m very surprised.
