Realistically, I'm not any form of expert on writing. I've been writing different versions of the same story for thirteen years, and I'm still not sure how to perfectly engage the modern audience. Regardless, I have still learned quite a bit on the subject of what direction a 21st century author should be taking.
If you're a student of modern art, you may notice that the most engaging pieces today are those that not only make a statement on life and / or society, but also break our immersion from normal trends. You can apply this to writing very easily. The way in which the old stories were written do not apply to the modern audience, as today, people have expectations to their most primitive desires. One can't simply make a traditional painting or story, and expect it to have the same effect today. People want action, violence, and tragedy in a setting that goes beyond the traditional.
I just got done reading your current version of Stolen. I believe it falls into the trap of tradition... taking used concepts and expected imagination and not really going anywhere engaging with them. One also cannot be very invested in your scenes, since your scenes are so brief. From the viewing of the cursed princess, to the embankment of Eric's journey, there is hardly enough meat to keep the audience invested in the moments. These situations need to be given more depth. They need personality and atmosphere in order to draw the reader in. I used to do the same thing... I was quite impatient and cared more about progression than depth. I had the story well in mind, yet I disregarded my audience for the sake of progression. I think you can manage to put far more life into this writing, even if it takes far more time and investment. You need to draw these scenes out more, use more of your own imagination, and put a personality in the writing.
You obviously have quite a few grammatical errors, but I don't believe those are important until the product is finished. The thing that bothered me the most was the tethering of the horse. No... one does not tether a horse. One hitches a horse. And don't do that all caps thing to show great emphasis. I always think it borders on uncontrollable insanity rather than just extreme rage. Our own Revorian HUNTER being a fine example of my view.
