I never knew about the Christian symbology relating to unicorns and dragons...interesting. But I wouldn't call what you've written a story exactly.

The first sentence is good and catches the readers’ attention, but then you jump right into another idea that is too sudden. You have your basic ideas for the story it sounds like, but you should expand upon them.

Who is Sarah? What's her personality? Why does she want to run away from Richard Cooper? Is he so horrible that she cannot stand the thought of marrying him, or maybe she is a free spirit and she feels like her family is trying to tie her down? Where did she find the unicorn and how? Was she shocked to see one, or are they a common sight? Ect.

If you answer questions like these you would have a whole long chapter, instead of this little bit you've posted.

I liked the idea of the unicorn wanting to use Sarah, but you really need to describe the story better. What you posted reminds me more of a summary.

If you update, I'll look again to see if you have added length and description. If you have you might have a faithful reviewer.

This was terrible, there was no form it was based on some pretty ** fairytale story, overratted and unrealistic for any probable age.. Though for now I will simply assume you are retarded, truly, no one I know who has any form of bright light inside of them, would ever dare to venture into the disgusting cliche that I know for a fact, thousands of other wannabe whorks have stalked on subject before you. Ugh, start writing realistically! love-Sharon
