Going to stop reading here... Not because I don't like, but in fact because I DO! I want to finish this story when I can get it in my hands. Very good job getting me hooked Mr. Kay.
This scene is hard to read. I severely dislike bullying. You have written this whole scene so well that I can quite literally feel the tension, like my jaw is clenching and my eyes are straying a little ahead because I want to know what's going to happen... Well done.
....hmmm.... I have a feeling this might be significant, but the way it's kind of snuck in here. I don't know. Foreshadowing? If this develops more, like Silas literally DOES have this power, that could get very interesting!
What if you were useless and your family gave you away to a sorceress? What if the sorceress refused to teach you magic? What if your amazing friendship with a dragon earned you the wrath of a god? How far would you go to fight for your friend?
