...A Harper Collins, eh? A budding publisher? Nice.
To be perfectly honest with you, I did kinda self-publish an ebook on Amazon Kindle store not too long ago. But I'm not expecting a miracle off that one - I speed wrote that baby in two and a half month, a 200 page thriller with a ton of bad langauges.
But the one I'm writing now, I'm paying it a good deal of attention. And so far, I have fairly early draft of first couple of chapters. It's an original story, of a fantasy war, some romance, tragedy, ton of action, maybe a little humor here and there. If you are still interested, I could email you those two chapters - but be warned, they are still in pretty rough shape.
