I love the way you wrote this! River is one of my favorite characters, so of course I was eager to read your story. Not only does it begin in an attractive manner and continue to maintain its interest, but all seems well with your grammar too.
Read the story now
The conclusion is rather open-ended, not that I can complain. It certainly leaves room for one’s imagination to create a number of possibilities for the future.
I know I’m supposed to say something at least a tad criticizing so that you have something to work towards. Alright. I’ll try, though I admit you make it difficult for me to find anything I dislike. Perhaps you might describe the man at the door a little better and say something more about River’s surprise and/or feelings just before she receives the card.
Quite a lovely story overall. Thanks for sharing it.
