Something that I didn't quite like was the too much use of telling sometimes. Like, "They shared the heartbreaking silence". You really need to say that the silence was heartbreaking? Show it! Make the reader feel it's heartbreaking. Saying that it's heartbreaking doesn't help me as a reader to identify in the feeling.
Everything IMHO of course. It's a good story. I know that there are no rules of writing but only guidelines. However, I really think the guideline, "show don't tell" is oughtto be followed. Not always, because you can't show everything. But you can't tell feelings. My opnion, as always.
Lovely story anyway. I loved Emma, she seems interesting, and Harry's reactions were truthful.
